Cannot Debug
Folks; This is XC2.4.1 on Tiger 10.4.11. (been at this level since 10.4.11) no recent system level changes. I'm doing Cocoa application development and all things are proceeding normally when suddenly I can no longer run the debugger. I have pretty stringent build rules but I get a good clean compile (no warnings). I have done a full Clean and Rebuild but still get the same results... I have restarted the machine but still get the same results... I can compile and 'Run' just fineBUT when I try to 'Debug' this is what appears in the console: tty /dev/ttyp1 Program loaded. sharedlibrary apply-load-rules all run [Switching to process 1243 local thread 0xf03] Running… Pending breakpoint 1 - "[NSException raise]" resolved Pending breakpoint 2 - "-[NSObject setNilValueForKey:]" resolved Pending breakpoint 3 - "-[NSObject release]" resolved 1 AppKit.subproj/AppKitGlobals.m: No such file or directory. in AppKit.subproj/AppKitGlobals.m 1 in AppKit.subproj/AppKitGlobals.m 1 in AppKit.subproj/AppKitGlobals.m ... (this last line will be repeated until I stop the process) I see the frameworks at /System/Library/Frameworks and they appear normal at least in a casual perusal... AppKit; Foundation and CoreData are all in the 'Other Frameworks' Group and are NOT checked for inclusion. I was not nor have been making app architectural changes for several days. Just normal code level debugging. Why does this only happen in Debug? What has happened? Any insight would be really appreciated!

How to debug a nib loading error?
Folks; Tiger 10.4.11 -- XC 2.4.1 I'm baffled by an IB error. Reasonable development has been on-going. Pretty stringent Build Rules and no errors or warnings. I decide to do a clean build, torch the app's prefs file and the CoreData store. I want to focus on the initial installation phase of the app... To my great surprise I cannot now get the app to launch successfully. It ran fine 15 minutes beforehand... Regardless of whether I 'Run' or 'Debug' I get the exact same result: I get all the way through the appDelegate's -awakeFromNib and the pref window opens (as I expect on first launch) but the debugger kicks in with the following: #0 0x90a594c7 in objc_msgSend #1 0xb7b8 in ?? #2 0x932849d8 in loadNib #3 0x932843d9 in +[NSBundle(NSNibLoading) _loadNibFile:nameTable:withZone:ownerBundle:] #4 0x9328403a in +[NSBundle(NSNibLoading) loadNibFile:externalNameTable:withZone:] #5 0x93283f7c in +[NSBundle(NSNibLoading) loadNibNamed:owner:] #6 0x93283cc3 in NSApplicationMain #7 0x00405ffc in main at main.m:18 In the Console I see: Normal log messages that I generate and expect (including the 'end-of-awake-from-nib' stamp) Program received signal: "EXC_BAD_ACCESS". I have the [NSException raise] as a Global breakpoint but it doesn't fire. Using the po command I can tell that MainMenu is the nib involved; the prefs window is in a separate nib... How do I track this down? Steve ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

XCode3 & NSLog & Tiger compatibility
Folks; I've finally begun to use XCode3 and I know I need to learn my way around the new world. I have an existing Tiger project that I will be shipping under Tiger but I need to ensure Leopard compatibility. So I can't convert it to the new world - I just need to be able to run/debug it. So immediately I run into the changes to Run log -> Console. OK - I try and understand what's going on but I can't seem to find anything useful which explains: If you have line of Tiger Code: NSLog(@"Hello World"); Where does this output appear in XCode3? I can see it sometimes in the Console.app but not reliably... (I have setup a database query for my 'Sender'.) I can see it sometimes in the Console log in XCode but not reliably.. I can't change the statements to ASL based statements per above.. How can I best use XCode3 to accomplish this mission? Thanks!

CoreData code working on Tiger - not on Leopard
Folks;
I am now testing a Tiger application on Leopard and learning the new
Leopard way at the same time.
I admit I have a lot of Leoparding to do!
I use Core Data (SQLite) pretty extensively on Tiger - life is good.
I take the project and run it without any changes to the model or the
code and Core Date won't save to disk.
I load a set of data on initial launch and at the end of that process
I have Core Data 'save'.
The data loading all appears to run fine:
recX = [NSEntityDescription insertNewObjectForEntityForName:@"XYZ"
inManagedObjectContext:moc];
[recX setValue:@"123" forKey:@"source"];
...
5 different entities and 1,000s of records..
I've looked over the 'Core Data - Release Notes' but I don't see
anything that seems to indicate a model conversion or persistant
store conversions I have not made any changes (no versioning...)
Here's the 'save' code:
- (void) updateCoreData {
NSManagedObject *moc = [self managedObjectContext];
[moc processPendingChanges];
if ([moc commitEditing]) {
NSError *error;
if ([moc save:&error]) {
if (error!=nil) {
On Leopard in the 'processPendingChanges' invocation I get the
following:
0 0x900ef0f4 in ___TERMINATING_DUE_TO_UNCAUGHT_EXCEPTION___
#1 0x93d680fb in objc_exception_throw
#2 0x9649a2a5 in -[NSManagedObjectContext
(_NSInternalChangeProcessing) _processRecentChanges:]
#3 0x964adbea in -[NSManagedObjectContext processPendingChanges]
#4 0x0002032e in -[AppDelegate updateCoreData] at AppDelegate.m:700
BTW: I also get a similar error if, during the loading, I try to get
a 'count' using a FetchTemplate with a null predicate (works on Tiger)
It appears the fetch also causes a 'processRecentChanges)
What am I missing?
Thanks for your help!
Steve

Re: CoreData code working on Tiger - not on Leopard
Folks;
I have a little more data on this issue:
After I have done any insert, if I subsequently call -
processPendingChanges I get an error in CoreData.
There are no pending messages in the log and no custom catch blocks
(other than what is show below).
The debugger halts on the @try command
The Code:
@try { [moc processPendingChanges]; }
@catch ( NSException *e ) {
NSLog(@"%@: Caught %@: %@", NSStringFromSelector(_cmd), [e name],
[e reason]);
}
The Log:
Program received signal: “EXC_BAD_ACCESS”.
The Stack:
#0 0x93d736ec in objc_msgSend
#1 0x9649aed1 in -[NSManagedObjectContext
(_NSInternalChangeProcessing)
_registerUndoForOperation:withObjects:withExtraArguments:]

#5 0x00089636 in +[DataImporter importSuppotDataInContext:] at

The Maddening Part:
All of the code works like a charm on Tiger.
I know I must be missing something pretty basic in the Leopard world
but I sure would appreciate a pointer to what that might be!
Thanks!

How to debug this Tiger release error?
Folks; On Tiger, I have an app that has a popup button which allows a user to make a selection from a supporting array. Once a new selection is made a collection of images are redraw in a view. Has been working reasonably well... Now sometimes, not consistently, when the selection is made the app will crash. Sometimes I see the following in the console log: 2008-03-19 01:36:20.231 XYZ[3035] *[XYZMainWindowController setUserSelectedData] XYZ(3035,0xa000d000) malloc: *** error for object 0x315730: double free XYZ(3035,0xa000d000) malloc: *** set a breakpoint in szone_error to debug I have the following environment variables set: NSZombieEnabled(YES) MallocStackLogging(1) and these Global Breakpoints set: [NSException raise] szone_error [NSObject setNilValueForKey] -[_NSZombie release] malloc_printf The crash doesn't appear to fire any of these breakpoints and leaves only this meager trace in the stack: #0 0x90a594c7 in objc_msgSend #1 0x00315730 in ?? #2 0x90824f84 in __CFDictionaryDeallocate #3 0x9080e0c6 in _CFRelease #4 0x927dc96f in NSPopAutoreleasePool #5 0x9328fab1 in -[NSApplication run] #6 0x932839c0 in NSApplicationMain#7 0x00405ffc in main at main.m:18 If I step thru the code it eventually starts off into the assembly code for handling the interface and bindings and as you all are well aware there is an astonishing amount of such code underlying the Mac OS interface If I pause the app and enable a breakpoint on [NSObject release] I get so many breaks that I just can't make any headway. How DO I -- most efficiently -- figure out what dictionary is the culprit in frame 2 above? Thanks for any help!

__setjmp linking error in Leopard
Folks; I'm trying to build a test case for a DTS support incident regarding an issue I posted earlier concerning CoreData in Leopard. I have an existing app which compiles without inicident on both Tiger & Leopard. To build the DTS test project, in Leopard I added the data model and several supporingt classes from this existing app, as well as the AppDelegate. I stripped out all the unnecessary code. I confirmed that all the build settings are identical. I did not write a single line of new code. I have the enable ObjC exceptions option turned ON. When I compile on Leopard I get: "__setjmp", referenced from: +[XYZBase allActiveInContext:] in XYZBase.o +[XYZXBase allActiveInContext:] in XYZBase.o +[XYZManagedObject allInContext:] in XYZManagedObject.o +[XYZManagedObject allInContext:] in XYZManagedObject.o -[AppDelegate(PrivateUtilities) setupDefaultSQLLiteStore] in AppDelegate.o -[AppDelegate(PrivateUtilities) setupDefaultSQLLiteStore] in AppDelegate.o +[Owner loadOwnerInContext:] in Owner.o +[Owner loadOwnerInContext:] in Owner.o +[DataImporter importSupportDataInContext:] in DataImporter.o +[DataImporter importSupportDataInContext:] in DataImporter.o ld: symbol(s) not found collect2: ld returned 1 exit status Build failed (1 error) All of the cited classes contain @try - @catch blocks. Is there another compiler setting I an not aware of? When I compile on Tiger: life is good! No warnings, no errors, runs flawlessly... Identical compiler settings! Man I had no idea how much grief I was going to run into just to get running on Leopard!!! I haven't even execised the bulk of the code I'm just trying to get out of -init!

Consistent Contextual Menu in NSTableview
Folks;
I'm having some difficulty getting consistent contextual menu behavior
in NSTableView.
In the Finder and iTunes (what I feel most users are familiar with) if
a row is selected but the user causes a contextual menu on a different
row then row selection changes.
(I don't want to start a UI flame about 'correctness') I'm only
interested in consistency!!
NOTE: the contextual menu can appear by a right mouse click, a two-
fingered tap, and a control-click which appear to be detected as
different events (see below)
The base NSTableView class does NOT change the selection when a
contextual click occurs on a row
If I sub-class and add:
- (void)rightMouseDown:(NSEvent *)theEvent {
[self selectRow:[self rowAtPoint:[self convertPoint:[theEvent
locationInWindow] fromView:nil]] byExtendingSelection:NO];
[super rightMouseDown:theEvent];
}
I get half-way home. Now the right mouse click and the two-fingered
tap will alter the selection.
BUT
the control-click does not.
The Cocoa adage, "if you are working too hard, you probably are" keeps
rummaging around my brain
What is the preferred means to efficiently make consistent contextual
menu behavior like Finder and iTunes?
Thanks,
Steve

AppleScript - occasional crashes on Leopard

Is a dual processor Intel creating a risk here? Is there something better I can do to handle the error? Why should I have to use a @try block here? I thought that was what the executeAndReturnError parameter was for!! But I don't get a chance to examine the errorDict.

Re: AppleScript - occasional crashes on Leopard
NO threading involved here. Just straight up Cocoa code... Do you know enough about AS internals to read the stack trace and KNOW that the error is during compilation? If so, why is the error not being propagated back thru errorDict? And the biggest mystery (to me anyway) why only sometimes?

Re: AppleScript - occasional crashes on Leopard
Mark; 10 months after the first Leopard seed to developers, 6 months after commercial release, and after 2 system updates to the commercial product, the message to developers using ANY AppleScript in Cocoa is: "No Garbage Collection for you!" Perhaps you can try and understand how this might be potentially irritating to some Turning off Garbage collection has profound impacts on the rest of the code base NOT just AppleScript. As I am sure you are aware, turning off Garbage Collection is WAY more than a compiler switch! For my ongoing better understanding of Cocoa, could you provide a link to where I SHOULD have researched so that I would not end up in this corner.

A Cocoa means to detect SysPref 'Enable access for assistive devices"
Folks; Is there a straight Cocoa means to detect the System Preferences/ Universal Access setting for 'Enable access for assistive devices'? I've found plenty of references on using Applescript to detect this setting. The Cocoa Assistive API seems pretty extensive but I can't glean a way to just determine this setting using Cocoa... I understand the potential 'admin' aspects of the setting. All I want is a means to know what the current setting is. Any links or code snippets appreciated!

ManagedObjectContext save issue
Folks;
I have a CoreData model working reasonably under Tiger now moving to
aggressive testing on Leopard.
I'm seeing something I don't believe I've never seen on Tiger...
The application has only one ManagedObjectContext. This is
established during the -awakeFromNib of the NSApp delegate.
Any other class which deals with the data does so by invoking [[NSApp
delegate] managedObjectContext].
I have a popup menu that controls a primary selection for the user
which restricts which objects are displayed currently.
Life is good. Change the popup selection --> see a different list of
objects!.
There is a reasonably complex set of preferences which is managed by a
single window with a toolbar and swapping in/out tabViews.
Nothing too outrageous but when the user closes this window I'm doing
a save on the MgdObjCtx:
(void) windowWillClose:(NSNotification *)notice {
NSManagedObjectContext *moc = [[NSApp delegate] managedObjectContext];
NSError *error = nil;
if ([moc commitEditing]) {
if ([moc hasChanges]) {
if (![moc save:&error]) {
NSLog(@"Error while saving\n%@", ([error localizedDescription] !=
nil) ? [error localizedDescription] : @"Unknown Error");
}
}
} else {
//MOC CommitEdit problem ...
}
}
I can change the popup's selection while the pref window is open and
all is well, but as soon as I close the window I get a failure.
If I comment out the MgdObjCtx handling above, everything works fine.
So should I just let it go and trust CoreData? But my brain wants to
understand and my paranoia says I'm better off getting it written on
the disk
The popup uses a fetchRequst to populate an array.
After closing the pref window (and thereby invoking the save above)
the MgdObjCtx is still valid and the fetchReques is found and
instantiated but the results are (null) whereas immediately before
closing the window the results would have populated an array.
I know I must be missing some key aspect of save but I am seriously
stumped here.
Thanks for any thoughts,
Steve

Cocoa string to carbon compatible C string
Folks;
I'm an ObjC guy who has to deal with some Carbon code that looks like
this:
#define kVERSION "abc"
#define kPARTNUMBER "123"
...
if ( (p_flag = initSomeSystem (
kVERSION,
kPARTNUMBER,
&errorCode))
== NULL) {
What I have to do is makethe kPARTNUMBER a value that is settable by
the user.
No problem collecting the data into NSString *partNumber.
So here's what I've done:
#define kVERSION"abc"
NSString * partNumber = [[blah blah] moreBlah];
.
const char * cPartNumber = [partNumber
cStringUsingEncoding:NSUTF8StringEncoding];
if( (p_flag = initSomeSystem (
kVERSION,
(char *) cPartNumber,
&errorCode))
== NULL) {
Is this correct?
Is there a better way?
When you use a directive like #define x "abc" -> there is an implicit
definition of x as a 'char *', is that correct?
Thanks for adding any clarity,
Steve

Re: Cocoa string to carbon compatible C string
Nick;
Thanks for the info, the deal is I don't have access to the source for
'initSomeSystem'.
So I can't answer your question, other than to point out what does
work..
I do know that ' #define kVersion "abc" ' creates a suitable string.
I'm trying to do the 'best' substitution I can with the fact that I
have an NSString and no access to the called method.
Hence my original question as the result of a #define x "123" being a
'char*'.
If that is true, then is the following the best solution?
#define kVERSION "abc"
NSString * partNumber = [[blah blah] moreBlah];
.
const char * cPartNumber = [partNumber
cStringUsingEncoding:NSUTF8StringEncoding];
if( (p_flag = initSomeSystem (
kVERSION,
(char *) cPartNumber,
&errorCode))
== NULL) {
Thanks,

It depends. Does the code take a real C string (char array), or does
it take an Str63 or Str255 or something? If the latter, then you
need to use CoreFoundation to get a Pascal string from the NSString.

Is checking -count worth it?
Folks; I'm really trying to learn how to write smart fast code. Code that takes maximum advantage of all of the battle-tested intelligence built into Cocoa/ObjC2. Now days with the "halo" and the "JesusPhone", I personally smell an excellent book opportunity... But enough chit-chat. I have a mutable array, M. I want to remove an object, O, from M; O might not be in M. M which is being constantly diminished could become empty. Is this code worth it? if ([M count]>0) [M removeObject:O]; OR should I just do [M remove O]; I assume that I can't write better code than the removeObject's use of -indexOfObject to determine the existence/location of O. So there I get 'best performance' for free by just getting out of the way and letting Cocoa do its thing. Is the only way to really tell to test?

A Mac App & helper NSStatusItem - how to share preferences
Folks; I have an application which will have an optional helper NSStatusItem. The statusItem is a stand-alone application which can be installed as a LoginItem. I want this status item to be able to read the preferences file from the application. The user sets a number of preferences in the normal app which influence both how the app and the status item should behave. I'm under the clear impression that I should not use the same bundleIdentifer for the application and the statusItem. They could both be running at the same time... Yet the bundleIdentifier seems to be the key to the file that [NSUserDefaults sharedDefaults] opens.. This not a managed environment nor is this issue related to users or hosts, so it doesn't seem that CFPreferences is called for (or even helps!)

I grant that there are some improvements which could be made, I
include them here in the spirit of helpfulness to the community
// myBundleID is a static string defined elsewhere
//retrieves the full user defaults dictionary
- (NSDictionary *) prefDictionary {
CFStringRef appBundleID = (CFStringRef)myBundleID;
return (NSDictionary *)CFPreferencesCopyMultiple(NULL, appBundleID,

}
//retrieves the string Value of a key [full implementation of all the

appBundleID, kCFPreferencesCurrentUser, kCFPreferencesAnyHost);
}
//sets the value for a key

Framework deployed to 'Resources' not 'Frameworks' in Contents
Folks; I've got two targets built from the same project: Big and Little Big has many resources, source files, as well as several frameworks that are copied and then deployed to a 'Frameworks' directory in the app file's 'Contents'. Little has many fewer of the resources and sources and only 1 of the framework.s. Big is just fine: compiles without complaint and runs as expected. Little's framework however gets deployed to the "Resources' directory on build. Little will compile without any complaints but crash immediately on 'dyld: Library not loaded: @loader_path/ Reason: image not found'.

respondsToSelector - #import OR compiler warnings?
Folks;
I have some methods which might be handled by one of several objects.
So I have a set of if ( [objectX
respondsToSelector:@selector(foo)] ) {... } else if ( [objectY
respondsToSelector:@selector(foo)] ) {... }
The functionality is fine but the compiler warnings for "no 'foo'
method found" bug me.
Call me finicky if you want but I love spanking clean compiles.
I can, of course, silence the compiler by #import the headers for
ObjectX and ObjectY.
But this leads to a level of dependancy and obfuscation that my gut
doesn't like.
Later I find myself asking "Huh, I wonder why this header is here?"
Or worse: "Dang, I can't just re-use this object here without also
dragging along that object?..arrghh"
So at the moment I add inline comments to the #imports statements to
aid in these later questions but this feels lame and is tedious as
well as error prone.
I realize that the runtime selection of the foo handler is the root
issue and I cannot ignore this when I might reuse.
So I don't want to 'bury' the issue.
But a full header import for the sake of a method or two seems onerous.
What do others think of this dilemma?
Should I just be glad of the warnings and get over it?
Am I getting too worked up on the #import issue?
Is there a compiler flag I could toggle on/off to suit? (XC3.1)

Re: respondsToSelector - #import OR compiler warnings?
Folks; Thanks for the rapid and thought-provoking responses!! Ken - I don't understand what you said about the method's signature's compliance with NSObject _protocol_. I looked at the protocol definition in the documentation and I just don't understand well enough to see what I could do to "side-step" the warnings, Would you be willing to spend another sentence or two on that? Bill - OK I have a lot to learn - studying AppKit's delegate implementation is a to-do! (gulp) In the meantime, tweaked your snippet and just added this at the end of the header of the class where the -respondsToSelector: issue arose: //respondsToSelector silencer - see -myMethodName @interface NSObject (MyClassName) - (id) foo; @end This silences the compiler without any #import being required in the .m file AND allows me to document to issue in the header where it seems to me it belongs. YAY!! Any downsides to this? I assume I could implement this declaration with the actual return expected (e.g. (NSDictionary*)) and squeeze even more assistance out that hard-working compiler, right? Thanks to all of you: Kyle, Graham, Ken and Bill for sharing your time and your knowledge!

Re: respondsToSelector - #import OR compiler warnings?
Ken; I think I get it now. In the simple case you describe below, use: someThing = [myObject performSelector:@selector(myMethod)] instead of someThing = [myObject myMethod] This seems quite useful!! performSelector's more ambitious cousins seem a tad less 'friendly' but I get the point! As always with you -> Quite Helpful!

I looked at the protocol definition in the documentation and I just don't understand well enough to see what I could do to "side-step" the warnings, Would you be willing to spend another sentence or two on that? Sure. Sorry if I was unclear. First, I only underlined "protocol" to make sure you looked in the right place in the documentation. The -performSelector:... methods are documented as part of the NSObject protocol, not the NSObject class. Second, the documentation for the -performSelector: method says the following: The aSelector argument should identify a method that takes no arguments. For methods that return anything other than an object, useNSInvocation. That's saying that the selector you pass to -performSelector: should be for a method which takes no arguments and returns an object pointer. This -- the number and types of arguments and return type -- is the "signature" of the method. The -performSelector:withObject: and - performSelector:withObject:withObject: methods similarly describe the signature requirements for the method identified by the selector you pass. So, if you are working with a selector for a method which matches the signature required by one of those methods, then you can safely use those methods. Doing so is a way to invoke the method without getting the compiler warning that was troubling you.

Re: respondsToSelector - #import OR compiler warnings?
Folks; This is a clarification for the record After some sleep and a cup of coffee and I realize that something I wrote was hasty, oh OK, sloppy! I took Bill's quoted example: @interface NSObject (MyClassOptionalMethodsThatMightBeImplementedByJustAboutAnything) - (void) someSpecial: (Sauce *) aSauce; - (BOOL) isBobYourUncle: (Child *) aChild; @end and morphed it to: //respondsToSelector silencer - see -myMethodName @interface NSObject (MyClassName) - (id) foo; @end It now seems to me that while attaching my tweak to the header does in fact silence the compiler, it is overly broad -> 'sloppy'. Why create a category on the entire hierarchy of NSObject? Why create the possibility (albeit remote) of category collision? A more targeted solution is: //subclass needs to provide for dynamic handlers @interface MyClass (RespondsToSelector) // see also usages of -performSelector() - (id) foo2:(id)param; @end This solution, combined with Ken's proposal to use -performSelector for the 'no parameters' cases, seems to give me a good solution. (Notice how Bill's example appears to presume this 'easy' use of - performSelector()!) Hope this is useful to someone else... Steve NOTE: -performSelector() does have permutations that would make it possible to not have the category declaration at all! ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: A Mac App & helper NSStatusItem - how to share preferences
Michael - So does the revised code below fix the leak?
After a bit more studying of the documentation, I offer these revised
'more Cocoa-friendly' updates:
The driving issue is a helper app which wants to access prefs written
by the 'motherApp'.
- (NSDictionary *) prefDictionary {
CFStringRef appBundleID = (CFStringRef)motherAppBundleID;
//Core Foundation 'create rule' sez I own this -> I must dispose of
it (because 'copy' or 'create' in CF method name)
CFDictionaryRef prefs = CFPreferencesCopyMultiple(NULL,
appBundleID, kCFPreferencesCurrentUser, kCFPreferencesCurrentHost);
//cast it into an auto-released Cocoa object
NSDictionary *result = [NSDictionary dictionaryWithDictionary:
(NSDictionary *)prefs];
//take care of the low-level memory issue
CFRelease(prefs);
return result;
}
It also may be worth pointing out that this dictionary only gets the
values from the permanent store.
So any registered defaults which the user has never changed do NOT
show up in this dictionary.
Now instead of using the low-level API to obtain individual values
simply access key-value pairs using the NSDictionary returned above.
This avoids having to write any further code to read motherApp's
preferences.
There are some stern words in the docs that weigh against
indiscriminate accessing using the low-level stuff, so just get the
dictionary and be done with it!
Now if helper MUST update a motherApp preference:
- (void) setPrefValue:(id)preferenceValue forKey:(NSString
*)preferenceKey {
CFStringRef appBundleID = (CFStringRef)motherAppBundleID;
CFPreferencesSetValue((CFStringRef)preferenceKey,
(CFPropertyListRef)preferenceValue, appBundleID,
kCFPreferencesCurrentUser, kCFPreferencesCurrentHost);
// as Jean-Daniel noted the line below is expensive and to be used
only as required
//that being said - it ain't on the disk until its on the disk
CFPreferencesSynchronize(appBundleID, kCFPreferencesCurrentUser,
kCFPreferencesCurrentHost);
}
NOTE: There is a CFPreferencesSetMultiple which allows for setting a
dictionary's worth of keys at once as well as specifying an array of
keys to be removed.
You still have to use CSPreferencesSynchronize if you want to get it
written
I hope this is useful.

Re: A Mac App & helper NSStatusItem - how to share preferences
Michael;
OK to really perhaps beat the poor horse, is the following kosher?
(NSDictionary *) prefDictionary {
return [(NSDictionary *)CFPreferencesCopyMultiple(NULL,
appBundleID, kCFPreferencesCurrentUser, kCFPreferencesCurrentHost)
autorelease];
}
Steve
Michael said:
Yep, this fixes the leak. Your Copy is balanced with a Release and all
is well.
However, just to be really nitpicky, I'll point out that it's a bit
ugly. You build a new dictionary from the old one, then throw the old
one away. Better to just keep the old one around with something like
this:
return [(id)prefs autorelease];
Or if you're in a garbage collected environment:
return NSMakeCollectable(prefs);
(And you can do both if you're writing dual-mode code.)

Immediate Nib Loading Error
Folks; I'm getting an immediate crash, before I can get anything written into a log (before any class +iniitialize). The stack at the crash is below. In the debugger (XC3.1) I enter 'frame 9' and then do a 'po *(id*) ($ebp+16)' to see what the offending object is but I just get "No symbol "id" in current context." I must be mis-remembering how to access arguments to the registers... There are NO non Cocoa objects in the visual display of the MainMenu.nib in IB3 (8 - NSCustomObject). What are all the '??' in this stack? (3-7) And what are the 2 at the lowest level? (16-17) Any thoughts on how to go about debugging this?

A Question on estimating +arrayWithCapacity
Folks; Under some circumstances I'm not sure how big a mutable object might need be. So is there any guidance on coming up with a value for capacity? Assume for these cases that reasonable guesses range from say 2 - 5000... I assume it's wasteful to just do a land grab with +arrayWithCapacity: 5000 but I also assume that it's unnecessarily burdensome to do +arrayWithCapacity:2. So is the 'best' +arrayWithCapacity:2500? It feels a little like premature optimization, but I do have to provide a value in the code Thanks for any feedback!

iTunes-like tail truncation for attributed strings

This is the only column in this tableView. This tableView is contained in a splitView which allows this 'nav' to be re-sized A lot of words to describe something quite similar to iTunes. As you reduce iTunes playlist column size toward its minimum, the playlists do a 'tail truncation' on any long text. How do I achieve that?

NSTextView and automaticLinkDetection
Folks; NSTextView has an attribute 'automaticLinkDetection' that can be set in IB or with the usual -set method. What the docs say is that it "...causes strings representing URLs typed in the view to be automatically made into links to those URLs..." This is what I observe. If I begin typing in the textView it will render a url into a clickable link. This is good! But what I am looking for is the ability to set a textView's stringValue (an NSString) and have any links in the text be reflected as links (as if I had typed them in) So the distinction is that there are no keyboard events to drive this evaluation. I notice that TextEdit does not do this if, for example, you paste a plain text snippet which contains a url into a Rich Text document. The links are not rendered clickable unless you generate a keyboard event which causes the url to get evaluated as such... So is what I am evisioning possible? I would not know ahead of time whether or not the text would contain any, one or many url... Thanks for any shared knowledge here!

Re: Core Data Predicate Builder - comparing dates
Ben; Thanks for taking the time to respond. I believe that I was blinded by a build issue in my allegation that the Predicate Builder mechanism was not giving correct results. This seems to be working fine now. I'm glad you have expressed the fragility issue on equivalence - I'll remember that. Thanks for the predicate in code. It's amazing how often the Cocoa answers are simple and straightforward when you finally see them. I might suggest the predicate you cited be considered for inclusion in the Apple documentation somewhere. Most (all?) the examples use operators and some fixed value. I know it may seem obvious (it does seem obvious now) but, when you don't know, a range of different examples can be a godsend... Thank-you!

XC & IB 3.2 overlapping siblings

Everything was peachy under 10.5 and XC3.1 no such warnings or errors. Sooo does this mean I cannot use XC3.2 unless I fix all these issues? Some are buttons that lie on top of each other and are hidden or shown based on data. How does one avoid the overlapping error in this circumstance?

Developing a Stand-Alone Service in Snow Leopard
Foks;
I'm trying to develop a stand alone service in Snow Leopard.
The issue I'm running into is how to update the system as I compile a
new version.
The pbs command shows that the bundle path is the one in my Release
Build folder
"pbs -dump_pboard"
{
NSBundleIdentifier = "com.myCompany.myService";
NSBundlePath = "/Volumes/myMacBookPro/Projects/XYZ/Code/
build/Release/MyService.service";
NSKeyEquivalent = {
};
NSMenuItem = {
default = MyService;
};
NSMessage = myService;
NSPortName = myServicePort;
NSSendTypes = (
NSStringPboardType,
NSRTFPboardType,
NSTabularTextPboardType
);
So when I recompile I do the following:
1) 'Uncheck' the item in the SysPref/Keyboard/Services list
2) Compile a new version
3) run "/System/Library/CoreServices/pbs"
4) 'Check' the item in the SysPref/Keyboard/Services list
5) Test the service by using the context menu (which is appearing at
the right time)
I have convinced myself that the only way to get Snow Leopard to
recognize the newer version of the service is to log out and back in.
This is tedious. Is there something I'm missing?

Re: Developing a Stand-Alone Service in Snow Leopard
Folks To clarify my initial problem statement: If I recompile and then issue a "pbs" and then invoke the service it continues to execute an earlier instance of the service -- NOT the freshly compiled instance…. This is easy to prove A set of followup questions on STAND-ALONE services 1) How do I programmatically 'check' the service in System Preferences/ Keyboard/Services? I offer the user the option of installing a service. If they elect to install it seems reasonable that they would want the service engaged. Is the only option to open the System Preferences at the pane? I offer the new shiny; the user says yeah let's use the new groovy stuff; An then I have to say "sorry I can't figure that out for you -- here's a window here's a whole bunch of scary looking text - give it your best shot… (seems pretty lame to me) 2) Since I offer the option to install, I offer the option to uninstall. Is it safe to do this? The .service bundle is marked as open by the system. Is it sufficient to do: if ([[NSFileManager defaultManager] removeFileAtPath:myServicePath handler:self]) NSUpdateDynamicServices(); Thanks for your time and consideration!

Interface Builder .xib deployment/development targets
Folks; I have an app with a 10.4 Deployment target. I have recently begun using XC 3.2 and IB 3.2 - spp compiles cleanly and all IB 'sibling' issues have been resolved. I've gotten a field report (release) where I'm seeing: 15:01:38.292 XYZ[11756:20b] HIToolbox: ignoring exception '*** -[NSCFString substringToIndex:]: Range or index out of bounds' that raised inside Carbon event dispatch This is occurring just as nib is about to open a first window. I've not seen this before and do not see it on my development machines (debug or release) Reporting machine is MacBookPro5,1 - 10.5.8 I have set the app's IB Deployment Target to 10.4 and IB Development Target to IB 3.2 Is there any reason to NOT use IB Development Target of 3.2? Any thoughts on this? It "smells" like its coming from IB not from Cocoa class methods… Steve ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Static Analyzer and Core Foundation
Folks;
Alert - potential boneheaded-ness lies ahead - please be gentle.
I'll be the first to admit that I'm much happier in ObjC than C…
I thought I would try static analysis and see what turned up.
On the whole I must say I'm pleased but this one has me questioning my
basic understanding
if (![[NSFileManager defaultManager] fileExistsAtPath:thisPath]) {
…
41 } else {
42 MDItemRef mdi = MDItemCreate( nil, (CFStringRef)thisPath );
43 if ( mdi != nil ) {
44 CFDictionaryRef dictRef = MDItemCopyAttributes( mdi,
MDItemCopyAttributeNames(mdi));
…
CFRelease(dictRef);
} else {
… handle error
}
}
Static Analysis tells me I have a potential leak of object allocated
on line 44 -- that's all.
My questions are:
1) Why is there not a warning for the object allocated on line 42 -
mdi ?
2) Why is the CFRelease(dictRef) not sufficient?
Thank you for you patience!

Re: Static Analyzer and Core Foundation

I've adapted the code to accomodate your's and Chris' answer to
question 2.
Here's the entire method, which now shows not static analyzer issues
but I still would like to understand why not.
+ (NSDictionary *)metadataForFilePath:(NSString *)thisPath {
NSDictionary *md = [NSDictionary dictionary];
if (![[NSFileManager defaultManager] fileExistsAtPath:thisPath]) {
NSLog(@"file does not existl");
} else {
MDItemRef mdi = MDItemCreate( nil, (CFStringRef)thisPath );
if ( mdi != nil ) {
CFArrayRef arrayRef = MDItemCopyAttributeNames(mdi);
CFDictionaryRef dictRef = MDItemCopyAttributes( mdi,
arrayRef);
md = [NSDictionary
dictionaryWithDictionary:(NSDictionary *)dictRef];
CFRelease(dictRef);
CFRelease(arrayRef);
} else {
NSLog(@"mdi is nil");
}
}
return md;
}
Is this the 'best' this can be?
Thanks for helping me learn,
Steve

MutableDictionary setValue:forKeyPath - strange behavior
Folks;
I have recently converted to XC & IB 3.2
I've updated my project to be a 3.2 project using a baseSDK of 10.6
with deployment target of 10.4
I've run the static analyzer and have no analyzer issues as well as no
compiler nor IB warnings
I'm feeling good about this but now code that worked under Leopard is
no longer working.
I have an instance variable which is an NSMutableDictionary *
myBaseSettings
I run a method which steps thru the keys in a local NSDictionary
(sessionSettings) to possibly set some values into myBaseSettings
NSDictionary * sessionSettings = ...;
NSArray *values, *keys = [sessionSettings allKeys];
int dictCount = [keys count];
if (dictCount>0) {
values = [sessionSettings allValues];
NSString *thisKey, *thisValue;
for (i=0 ; i(NOTE: I use setValue:forKePath because the sessionSetting keys can be
dictionaries)
I get an exceptions thrown whenever thisKey is a normal 'key' (ie
"workPhone") but NOT when thisKey is a 'keyPath' (ie.
"nameDict.firstName")
'*** -[NSCFDictionary setObject:forKey:]: mutating method sent to
immutable object'
The key and value are both valid strings (verified using 'po' gdb)
It seems like somehow the instance variable is not being treated as an
NSMutableDictionary but why?
Thanks for any thoughts on this - I'm baffled!

Re: MutableDictionary setValue:forKeyPath - strange behavior
Kyle; Thanks for such a speedy response. (and on a Sunday afternoon too!) That code is a fairly complex set of interlocking methods.

Re: MutableDictionary setValue:forKeyPath - strange behavior
Kyle;
In order to answer your request, I've gone back through the code that
generates myBaseSettings
essentially it is:
NSMutableDictionary *localDict = [NSMutableDictionary
dictionaryWithCapacity:70];
[localDict setObject:[self generateInterestingValue1]
forKey:@"interestingKey"];
…
…
[self setMyBaseSettings:localDict];
where setMyBaseSettings is an old-school KVC setter method
- (void) ssetMyBaseSettings:(NSMutableDictionary *) newSettings {
if (myBaseSettings!= newSettings) {
[myBaseSettings release];
myBaseSettings = [newSettings retain];
}
}
Does this provide you the information you are looking for?

Re: MutableDictionary setValue:forKeyPath - strange behavior
Folks;
Thanks for all of the guidance! I have found the issue.
It turns out that [localDict copy] is what was being sent to the
setBaseSetting.
In dealing with the static analyzer's warnings I must have made this
change and then had failed to back it out…
MY BAD
Removed this and all is well again.
A tip of the hat to Kyle for immediately sending me in the right
direction.
Karl - darn fine point about the random nature of 'allKeys'
(this code has been working fine for months - but I will stop relying
on this 'side-effect')
Thank-you all

This is good.
- (void) ssetMyBaseSettings:(NSMutableDictionary *) newSettings {
There's an extra "s" in here… does this mean you didn't actually
copy/paste the setter from your code? Or maybe you're using a
synthesized @property(copy) getter but a manually implemented setter,
and because you have typo'd the setter method, the compiler is
synthesizing one for you instead?

Data Model Versions and -fetchRequestTemplateForName
Folks;
I have recently converted to XC & IB 3.2
I've updated my project to be a 3.2 project using a baseSDK of 10.6
with deployment target of 10.4
I have a Core Data model that I've been very happy with starting in
10.4 and continuing in 10.5..
In readying for the brave new world ahead I have added a 'version' to
the data model.
I see 2 xcdatamodel documents (app1 and app2) - they are the same at
this point
After bring the app up to the tools and project setting described
above I've begun testing the release product on Tiger, Leopard , and
Snow Leopard.
The following method worked fine on all 3 OSes before these changes
- (NSArray *) elementsByTemplate:(NSString *) templateName {
NSError *error = nil;
NSArray *results;
//moc is an instance variable for the managedObectContext
NSFetchRequest * fReq = [[[moc persistentStoreCoordinator]
managedObjectModel] fetchRequestTemplateForName:templateName];
@try { results = [moc executeFetchRequest:fReq error:&error]; }
@catch ( NSException *e ) { NSLog(@"(Template:%@) Caught %@: %@ \r
%@", templateName, [e name], [e reason], [e userInfo]); }
if ( error != nil) { NSLog(@"%@ - Caught %i: %@ info = %@",
NSStringFromSelector(_cmd), [error code], [error domain], [error
userInfo]); }
return ( (results==nil) ? [NSArray array] : results);
}
This fails on Tiger BUT continues to work normally on Leopard & Snow
Leopard.
fReg is NULL on Tiger (used to work fine on Tiger)
so the exception get caught with 'fetch request must have an entity)
[Yeah - so I do see that I should test for a null fetchRequest but
that's not the issue really!]
Is the model versioning the problem? Can I 'undo' that?
(I can't do a 'fetchRequestTemplatesByName' because that was
introduced in 10.5)
Is there something I can do or that I am overlooking?
I have backed the base SDK down to 10.5 (I can easily because I just
made that change to 10.6 and have no embedded 10.6 code as yet)
It still fails for Tiger.
I have also removed app2 from the xcdatamodeld bundle but this also
does not change the result.
I'm stumped on what to do to remedy this situation!
Thoughts?

Static Analyzer Question
Folks;
I have a Clang issue that is making me a little crazy.
I have a modestly complex Core Data application with several thousand
lines of code.
I've run Clang and at this point I have only one issue:
"…. Object with +0 retain counts returned to caller where a +1
(owning) retain count is expected"
this is shown at the end of a particular method.
The deal is that, over time, I have isolated this method and at this
moment there are NO methods which call it.
I cannot leave it like this - this isolation is a result of honing in
on the Clang issue...
A very common pattern for my application looks like this:
+ (NSString *) fooBar {
NSString *result = @"";
…..
if (x) {
result = @"1";
...
} else {
result = @"2";
}
return result;
}
Yes this is a class method - I use this pattern for both class and
instance methods.
This is the only method that Clang has an issue with…
Why does Clang believe that an 'owning retain count is expected' if
the method is never called?
Why is Clang picking on this one method which mirrors the mechanics of
so many others?
Any thoughts appreciated!
Steve

I think this means the method has a name that by convention
indicates that it returns a reference the caller must release — i.e.
a prefix of "alloc" or "copy" or "mutableCopy"
+ (NSString *) fooBar {
NSString *result = @"";
…..
if (x) {
result = @"1";
...
} else {
result = @"2";
}
return result;
}
What's the actual name (not 'fooBar')?
Why does Clang believe that an 'owning retain count is expected' if
the method is never called?
Objective-C is a dynamic enough language that there is no way to
tell at compile time whether a method is reachable or not. Even if
that selector never appears in your code, it could be constructed at
runtime, or your code could load a plugin bundle that calls that
selector.

Re: Nib Loading Crash on Tiger only -- SOLVED (well made gone...)
Folks; I opened the .xib file in a text editor -searched for 'NSCoreUIImageRep' I found one instance (thankfully) and by 'reading' the text was able to determine that it was a matrix of 2 radio buttons. I removed the offending matrix and re-instantiated a fresh one. I monitored the .xib text as I re-sized it but was unable to generate a 'NSCoreUIImageRep' again. Compiled - deployed to Tiger -> works fine…. I dunno, my gut tells me that there is some way thru resize and cell spacing that IB 3.2 will use a 'NSCoreUIImageRep' but I gotta move on… Never was any IB warnings or errors….

Re: rangeOfString & UTF8 - SOLVED
Clark;
OK thanks for the whack on the head…
I had managed to convince myself that there was something about the
utf8 umlats and all that I wasn't understanding …
No the problem was simply that there was a trailing space at the end
of tString -> 'Geschäftsführer (CEO) '
Thanks for your time!

Coding around a known bug
Folks: I'm looking for some advice on how to code around a Leopard bug (radar 5905139 & 5599887). Leopard broke the following: OSStatus returnCode = TransformProcessType(&psn, kProcessTransformToForegroundApplication); TransformProcessType used to bring a background app to the foreground, which it still does EXCEPT for the fact that the menubar does not get correctly established until the user first brings another app to the foreground and then re-establishes the 'wounded' app as the foreground. Once this 'app toggling' is done, all is well. So I can trap Tiger v. Leopard and do toggling only on Leopard, that's pretty straight-forward. What I'm looking for is best advice on how to get the menubar to be 'right' in code. I've tried: [[NSWorkspace sharedWorkspace] launchApplication:@"Finder"]; followed by an Applescript to 'activate' myself. OK it works, but it jarring to have the 'Finder' just suddenly jump into view and I'm quite sure customers will NOT like it. Any thoughts? Also any thoughts on how possibly to code this so that when, or if, Apple ever fixes TransformProcessType that the fix might right itself and not require a new version.

Launch Path Not Accessible
Folks; I'm trying to do something that seems like it should be easy, but I'm stymied by what I think is a permissions error I don't understand. I'm trying to run a script using NSTask. I have the static script stored as a separate file in my bundle. I have created a folder in my "Applications Support" directory called "Scripts" and copied my script and several items into this directory. Note that this has a space in the full pathname! SO I have tried the following: NSString *myScriptPath = [[self scriptsFolderPath] stringByAppendingPathComponent:@"myUseful.script"]; //yes I have verified this is a valid path!!! NSTask *task = [[[NSTask alloc] init] autorelease]; [task setLaunchPath: myScriptPath]; [task setArguments:[NSArray arrayWithObject:...]]; [task setStandardInput:[NSPipe pipe]]; [task launch]; ERRROR: launch path not accessible So, thinking that the 'space' maybe wanking out the 'setLaunchPath' I tried to convert to a 'safe' url path: NSURL *myScriptFileURL = [NSURL fileURLWithPath:t]; ... [task setLaunchPath:[myScriptFileURL absoluteString]]; Same error! The docs don't make it clear TO ME why I would need special permissions to launch a script in my own "App Support" directory. Am I out in the weeds chasing the wrong rabbits? Any guidance appreciated!

Re: Launch Path Not Accessible
Andrew:
Thanks for the slap on the head!
So I chmod'ed the file and no longer get the 'not accessible error'
YEAH!
BUT now I get:
*** NSTask: Task create for path '/Users/steve/Library/Application
Support/XYZ/Scripts/myUseful.o' failed: 88, "Malformed Mach-o file"
So I must be missing something about the contents of script files.
Here's my script:
myUseful.m
#import
int main(int argc, char **argv)
{
char dummy;
read(STDIN_FILENO, &dummy, 1);
[NSAutoreleasePool new];
NSURL *url = [NSURL fileURLWithPath:[NSString
stringWithUTF8String:argv[1]]];
LSOpenCFURLRef((CFURLRef)url, NULL);
return 0;
}
You will just have to trust me that I DO need to launch the file in
this manner.
What do I need to do to this file to make it into the correct format?
THANKS AGAIN for the chmod help!

Nope. NSTask takes a filesystem path, not a URL.

Re: Coding around a known bug - SOLVED (acceptably)
Andrew & Aaron
Yes I have read the discussion in the docs related to
TransformProcessType(). My bad - here's a more complete snippet:
if (...some condition..) {
ProcessSerialNumber psn = { 0, kCurrentProcess };
OSStatus returnCode = TransformProcessType(&psn,
kProcessTransformToForegroundApplication);
if( returnCode == 0) { SetFrontProcess(&psn); }
}
The result of this is that an icon does appear in the dock BUT the
menubar is NOT shown until the application toggling business I
described in the initial email occurs.
I've also tried all Aaron's various suggestions related to NSMenu, and
NSApplication all with the same result.
Seems to me TransformProcessType(&psn,
kProcessTransformToForegroundApplication) leaves the transformed
process in a strange state; a state not expected by NSApplication.
So here's what I've finally gotten to as an acceptable solution.
This flashes the menubar but otherwise the context switch is as
expected - no unexpected app jumps to front.
(AppleScriptTool is a custom object which has various convenience
methods I've developed)
NSString *currentApp = [AppleScriptTool stringFromAppleScript:@"tell
application \"System Events\" to name of first process whose frontmost
is true"];
ProcessSerialNumber psn = { 0, kCurrentProcess };
OSStatus returnCode = TransformProcessType(&psn,
kProcessTransformToForegroundApplication);
if( returnCode == 0) {
[[NSWorkspace sharedWorkspace] launchApplication:currentApp]; //
this step is necessary - if left out the menubar is not updated
[AppleScriptTool
bringApplicationToFront:myAppName]; //uses @"tell
application \"[EMAIL PROTECTED]" to activate" [NOTE: SetFrontProcess() doesn't work]
}
I cannot use NSWorkspace's -activeApplication in the first line
because it sees the calling app as the active app...
It also seems to me that when (if) Apple does fix
TransformProcessType(), since the call to SetFrontProcess() is spelled
out as necessary, that my solution will not break nor result in
undesired behavior.
Maybe someone else will find this useful...
Thanks to all,
Steve

Hi, Steve,
The docs appear to mention something that may be of use -- see the
Discussion for TransformProcessType():
You can use this call to transform a background-only application
into a foreground application. A foreground application appears in
the Dock (and in the Force Quit dialog) and contains a menu bar.
This function does not cause the application to be brought to the
front; you must call SetFrontProcess to do so.
Apologies if you are already, but -- are you calling
SetFrontProcess()?
Cheers,
Andrew

Restarting an app -- AppleScript 'launch' in a detached shell
Folks; I am trying to simply restart my app. To my dismay, I cannot find a way to do this in Cocoa. Please enlighten me if I have failed to understand something!! After perusing the archives, what makes the most sense to me is to launch a detached shell that executes a simple AppleScript. The script has a delay of 2 seconds and then simply does a 'launch'.

[task setStandardError:[NSFileHandle fileHandleForWritingAtPath:errorOutPath]]; [task waitUntilExit]; // <-- I've also tried [task launch] but the same result. [[NSApplication sharedApplication] terminate:self]; This unsurprisingly DOES quit the application but the script doesn't appear to execute, nothing further happens... Am I not using the argument list correctly? I also do not see anything at all in the file @ errorOutPath nor do I don't see any console messages. How could I pick up any data on what IS happening? I know I am missing something here but I AM puzzled... Thanks for any help!

Re: Restarting an app -- AppleScript 'launch' in a detached shell
Andrew;
OK for the sake of the group I will parade my ignorance so that
perhaps others can learn too...
First I do understand your point that using AppleScript is using an
unnecessary high-level tool when a lower-level tool will do!
Thanks for keeping me on-point there!! Good old-school unix thinking
- always a good thing.
I have 4 questions
1) Given that it is higher-level than necessary, I would still
appreciate understanding why it doesn't work.
I revamped the '&' and added it to the end of the osaxscript command
instead of passing as argument -> no change..
2) In the script you cited, I don't understand the 'if(fork() ||
fork())' conditional test. Can you clarify this statement?
3) Why are you using 'execl' and not 'exec'?
4) When you say "...launch this with a single argument..." I' not
sure of exactly what you mean. Launch how?
I tried creating a text file with your script as the contents
(Restart.unixscript)
//enclose the paths in single quotes because there are potentially
spaces in either path (eg 'Application Support')
NSString *scriptPath = [NSString stringWithFormat:@"'%@'",[[self
scriptsFolderPath]
stringByAppendingPathComponent:@"Restart.unixscript"]];
NSString *myPath = [NSString stringWithFormat:@"'%@'",[[NSBundle
mainBundle] bundlePath]];
NSFileHandle *stdErrors = [NSFileHandle
fileHandleForWritingAtPath:@"/Users/steve/Desktop/RestartErrors.txt"];
NSTask *task = [[NSTask alloc] init];
[task setLaunchPath:@"/bin/sh"];
[task setArguments:[NSArray arrayWithObjects:scriptPath, myPath,
nil]]; // no -c means that first parameter is file of commands
[task setStandardError:stdErrors];
[task setStandardOutput:stdErrors];
[task launch];
[[NSApplication sharedApplication] terminate:self];
When I do this I get the following in stdErrors:
/bin/sh: '/Users/steve/Library/Application Support/XYZ/Scripts/
Restart.unixscript': No such file or directory
NOTE: enlosing in double quote doesn't change the result; nor
obviously does not enclosing the paths in a delimiter at all
Seems like I'm missing something
Thank-you for your patience on this!

You're overcomplicating things.
int main(int argc, char **argv) {
if(fork() || fork()) exit(0);
sleep(2);
execl(argv[1], argv[1], NULL);
exit(1);
}
Launch this with a single argument - the path to your application's
executable. It'll background itself, sleep two seconds, and exec
your application.
(Standard disclaimer: typed out in Mail, untested.)
I've got the script working like a champ in a straight terminal
session:
> /usr/bin/osascript '/Users/steve/Desktop/Restart.script'
So now:
NSString *cmdString = [NSString stringWithFormat:@"/usr/bin/
osascript '%@'",[[self scriptsFolderPath
stringByAppendingPathComponent:@"Restart.script"]];
NSTask *task = [[[NSTask alloc] init] autorelease];
[task setLaunchPath:@"/bin/sh"];
[task setArguments:[NSArray arrayWithObjects:@"-c", cmdString, @"
&", nil]]; //the '&' detaches the shell, yes?
& only detaches a command when it's part of a shell command. You're
passing it as an argument to /bin/sh here, which is subtly different.

CoreFoundation Command Line Tool - an easy beginner question
Folks;
Here's the pretty simple tool I'm trying to create (THANK-YOU Michael
Ash!!)
int main (int argc, const char * argv[]) {
char dummy;
read(STDIN_FILENO, &dummy, 1);
[NSAutoreleasePool new];
NSURL *url = [NSURL fileURLWithPath:[NSString
stringWithUTF8String:argv[1]]];
LSOpenCFURLRef((CFURLRef)url, NULL);
return 0;
}
I'm using XCode3.1 with the 10.5 SDK deploying to 10.4.
I open new project using the CoreFoundation - Command Line Tool
template, and place the code shown above.
My question is what are the #imports necessary to make this work?
I have figured out:
#import
//for the STDIN_FILENO and the read()
#import //for the
LSOpenCFURLRef
I've tried various usages of #import but
can't seem to get it right so that NSURL & NSAutoreleasePool are
defined...
I believe that both NSURL and NSAutoreleasePool are defined in the
Foundation framework, which is why I am focused on getting it
#imported, I just need the syntax..
(with Foundation framework added to the project)
NO --> #include (~700 errors...)
NO --> #include (45 errors..)
Oh out of exasperation, I tried ---> ~1700 errors
I know this is probably pretty easy for most, but its got me just
bamboozled
THANK-YOU for any help!

StatusItem to foreground app
Folks;
I'm building a tool that I want to allow the user switch 'modes'
either running as a menubar statusItem or as regular dock-based
application.
NOTE: The info.plist has LSUIElement=1.
If the user designates the application to run as regular dock-based
application then, early in startup, I do:
ProcessSerialNumber psn = { 0, kCurrentProcess };
OSStatus returnCode = TransformProcessType(&psn,
kProcessTransformToForegroundApplication);
if( returnCode == 0) {
...
I have this working fine under Leopard, however, the application's
deployment target is 10.4.
On the Tiger machines I'm getting a returnCode = -50.
GetMacOSStatusErrorString tells me that there is an error in the user
parameters.
I have examined the psn high = 0 and low = 2 which seems right to me...
The 10.4 application does NOT die; rather it continues to load and run
EXCEPT there is no menu bar, no dock icon, and it is not listed in
'Force Quit'. (The TransformProcessType has failed.)
Is the LSUIElement confusing 10.4?
Was this a known bug on 10.4 that was never fixed?
Was there a 10.4 workaround?
So here's my predicament:
I need the LSUIElement set to run as a statusItem (yes?)
LSUIElement cannot be changed by code (yes?)
If I have this set LSUIElement then I can ONLY run as a status item in
10.4.
If I do not set LSUIElement then I can NEVER run as a status item in
either Leopard or Tiger
I really don't want to deploy separate binaries for obvious reasons.
Does anyone have any insight into what is going on here?
Thanks for any thoughts!

Built Menu not firing the action
Folks;
I'm building a data driven submenu programmatically.
The submenu appears correctly in the UI with the correct titles but
nothing happens when these items are selected.
submenu build code:
menu1 = [[[NSMenu alloc] initWithTitle:@"__"] retain];
[menu1 setAutoenablesItems:NO];
NSEnumerator *titleEnum = [someArray objectEnumerator];
while ((nextTitle = [titleEnum nextObject])!=nil) {
[menu1 addItemWithTitle:nextTitle action:@selector(customAction:)
keyEquivalent:@""];
}
...
[[mainMenu itemAtIndex:3] submenu] itemWithTag:1000] submenu]
itemWithTag:1003] setSubmenu: menu1];
I spit menu1 out to NSLog and it looks fine.
I set a breakpoint at customAction: it NEVER gets called.
(Yes I have spelled it correctly [- (void) customAction:(id)sender;]
This is on the mainMenu in the main XIB file. There is an outlet from
appDelegate for mainMenu, this is set.
The menu itself has the appDelegate set as its' delegate.
The selector method is o method in the appDelegate object.
There are no selector bindings set.
(Note: there are enabled bindings set which are working correctly)
I'm just stumped! I probably could use some sleep...
Also how do you show some useful data from a SEL value in NSLog? ie
print [NSMenuItem action]?
Since nothing happens how do I debug this?
Thank-you for any insights!

Re: Built Menu not firing the action
Peter; Thanks for the tip on NSStringFromSelector()! On the responder chain: I'm not sure I precisely understand your question - where are you expecting me to call this? If I call it at the time the submenu is being constructed I get: appDelegate Since I can't get any response to selecting the item itself, I can't tell you what I would get if I called it when the item is invoked =;-( If you use the NSMenu method -addItemWithTitle:(NSString *) action: (SEL) keyEquivalent:(NSString *) what is the recommended way to set the target for the menuItem added by this method? Why doesn't the method allow you to set the target as well as the selector, in one fell swoop? How can I effect the responder chain, if I am just adding a submenu to menuitem on the menubar? The REAL maddening thing here is that I have another similar data driven submenu that uses the same mechanism and it works fine. I've been over and over the IB settings for the darn things and I can't find any differences! Same point in time the submenu are being constructed and attached; and same exact objects involved in the selector Thanks for any additional data.

Strange Strange Bug
Folks; OK this behavior has me a little spooked... This behavior occurs the first time through the method! I have a breakpoint set at the first line of a method, which happens to be a NSLog(@"Ready"); As is normal I have my local variable declarations at the beginning of the method: NSArray *myKeys, *workingValues; NSString *gAsOf, *gAsOfDate, *gDataMask, *gDataMaskName, *gID, *gIDName, *gVersion, *gVersionName; gAsOfDateName = [[NSUserDefaults standardUserDefaults] stringForKey:@"groupAsOfDatePropertyName"]; gDataMaskName = [[NSUserDefaults standardUserDefaults] stringForKey:@"groupDataMaskPropertyName"]; Nothing surprising or complicated... However, the console window will show at least two of these messages:. 2008-09-05 00:56:45.101 XYZ[345:813] *** -[CFString _cfTypeID]: message sent to deallocated instance 0x16d1db80 2008-09-05 00:56:45.563 XYZ[345:813] *** -[CFString _cfTypeID]: message sent to deallocated instance 0x16d1db80 2008-09-05 00:56:46.776 XYZ[345:813] *** -[CFString _cfTypeID]: message sent to deallocated instance 0x16d1db80 If I scroll the variables display at the upper right in the debugger window, the console will add more of these messages.

For this string variable the 'Summary' will be empty as opposed to all other 'Summary' which have 'Invalid' The debugger is paused several lines above the declaration of this variable... If I merely switch the positions of the variables I can change which variable has the 'bad' instance id. It is always the 6th declared string variable.

Re: Strange Strange Bug
Kai; OK That seems reasonable but: why do I not see this behavior anywhere else? why have I never seen it before now? why if I restart XCode does the 'bad' instance fall on exactly the same string? Thanks, Steve On Sep 5, 2008, at 4:11 AM, Kai wrote: Steve, looks like the debugger tries to inspect your uninitialized string pointers. And it happens that the stack location assigned to the 6th string pointer still contains the address of a now deallocated object left there when another method exited. So this is a debugger-only problem and completely harmless without debugger (if I am not mistaken, of course). To fix it, assign nil to the string pointers when you declare them: NSString *gAsOf = nil; etc.. Or, better yet, do not declare the variables before using them (that is, not all together at the start of the method). (Note that this style may be only possible with certain C dialects. I use Objective C ++, therefore I’m not sure). Hope this helps. Kai On 5.9.2008, at 09:04, Steve Cronin wrote: Folks; OK this behavior has me a little spooked...

Dragging tableView rows to an external applications
Folks; I'm trying in 10.4+ to implement dragging data from a tableView to the desktop. My problem is probably a dunderhead oversight but I can't see it. I have NOT subclassed an NSTableView. In a windowController I do the following in -awakeFromNib: (myTableView is an Outlet) ... [myTableView registerForDraggedTypes:[NSArray arrayWithObjects:NSFilenamesPboardType, NSFilesPromisePboardType, nil]]; [myTableView setDraggingSourceOperationMask:NSDragOperationNone forLocal:YES]; //local [myTableView setDraggingSourceOperationMask:NSDragOperationCopy forLocal:NO]; // external ... I get a local copy, drag some selected rows initiates a 'carrying' cursor, but as soon as I leave my application it invalidates. This is exactly the opposite of the desired/expected behavior... NOTE: If I change both drag operations in the setDraggingSourceOperation method to NSDragOperationEvery - no difference. myTableView has the windowController set as its delegate. The tableView:writeRowsWithIndexes:toPasteboard is being called (its in the windowController too) What am I overlooking?

Horizontal SplitView Resize Question
Folks; I have a horizontal split bar inside of a resizable view -the parent view grows both horizontally and vertically. The standard behavior for horizontal split views appears to be that the the bottom view is grown or shrunk. (In my testing this is true regardless of the resize attributes of the enclosed bottom view) I have ALL of the resize widgets set ON for this splitView. What I would like is the divider to stay fixed at its current height from the bottom throughout a resize and the top view to grow or shrink. Is there a setting I am overlooking or is the way to accomplish this by overriding -splitViewDidResizeSubviews?

NSIndexSet isEqual: sent to deallocated instance
Folks; I have two custom tableViews and two custom arrayControllers. The reasons for the custom objects are so the UI can respond to specific key events and for drag and drop support. Both tableView have their appropriate arrayControllers designated as delegates and datasources. The tableViews use bindings to define the column values. The selection in one tableView controls the content of the other - this is implemented by using 'filteredArray' against a 'backing' array. Overall, this is largely working pretty well. Under some circumstances the the backing array is refreshed with new content. When this happens, sometimes, not always, an error is thrown: *** -[NSIndexSet isEqual:]: message sent to deallocated instance 0x184de440 #0 0x92028907 in ___forwarding___ #1 0x92028a12 in __forwarding_prep_0___ #2 0x967fadb9 in _NSValuesAreEqual #3 0x9683e9e6 in -[NSTableBinder _updateSelectionIndexes:] #4 0x9683e073 in -[NSTableBinder _observeValueForKeyPath:ofObject:context:] #5 0x9683dd6d in -[NSTableBinder observeValueForKeyPath:ofObject:change:context:] #6 0x93d77ece in NSKVONotify #7 0x93d08465 in -[NSObject(NSKeyValueObservingPrivate) _notifyObserversForKeyPath:change:] #8 0x9661cd7a in -[NSController _notifyObserversForKeyPath:change:] #9 0x9661cc7b in -[NSController didChangeValueForKey:] #10 0x96838ce4 in -[NSArrayController didChangeValuesForArrangedKeys:objectKeys:indexKeys:] #11 0x9683bb44 in -[NSArrayController _arrangeObjectsWithSelectedObjects:avoidsEmptySelection:operationsMask:useBasis :] #12 0x96836a7a in -[NSArrayController setContent:] #13 0x9683d2a2 in -[NSArrayDetailBinder _refreshDetailContentInBackground:] #14 0x93d77ece in NSKVONotify #15 0x93cf4392 in -[NSObject(NSKeyValueObserverNotification) didChangeValueForKey:] #16 0x000cb3a9 in -[MyWindowController refreshViews] at MyWindowController.m:347 I do not have either tableViews 'selectionIndexes' bound.

10.4 v. 10.5 SDK question
Folks; I have developed an application with XC 3.1 on a 10.5 Intel machine using the 10.5 SDK w/ a 10.4 deployment target. (No GC for me!) In testing I immediately ran into a few difficulties on a 10.4 PPC machine. In the course of tracking down these issues I ended up installing XC 2.5 on this 10.4 PPC machine. I actually compiled the application under the 10.4 SDK on this machine so I could run it in the debugger. (I had to make surprisingly few changes to get this to happen - none that I am unhappy about) Converting all .xib to .nib being one major aspect (and where I found the offending bug [filter predicate bindings...]) In fact, this exercise has left me with an increased confidence in the application's behavior in this environment. So I've moved the modified project back to the 10.5 Intel where it happily compiles and runs still using the 10.4 SDK and .nibs. So, given all that, am I correct in wanting to move the project back to the 10.5 SDK because the underlying code is cleaner and the compiler output is better? (Yes, I do understand the benefits of .xibs but let's leave that aside for now) Frankly, I would like to better understand all the implications of this choice. Thanks for any input!

Re: 10.4 v. 10.5 SDK question
Ken; Thanks for the quick and helpful response! You seem to have assumed that you can only compile against the 10.4 SDK by going back to Xcode 2.5 (and thus using an earlier compiler). No I brought the application back to the 10.5 machine and have left it compiling against the 10.4 SDK for now. Trying to decide whether to return to using the 10.5 SDK was the genesis of my question. In general, your choice of SDK should be dictated by the latest features you want to use. If you don't want to use any 10.5-or- later-only features, sticking with the 10.4 SDK is safest. I want to deploy to 10.4 and have avoided using 10.5 features to keep the code base clean and simple. My plan was to prove out the product idea using the widest possible audience (10.4) using the simplest most widely understood and sampled code - 10.4 only. If successful, then version 2 would be a 10.5 only product developed using a by then more battle-tested 10.5. Version 2 is also then a clean code base because it also avoids all the OS-version conditionals you mentioned. Also, what do you mean "the underlying code is cleaner"? .. One caveat with simply using the 10.4 SDK, though -- the 10.5 frameworks contain a number of bug fixes That's what I meant. ...(bug fixes) which are only enabled for binaries linked against the 10.5 SDK. This is both a good and bad thing. It means your program works consistently on Tiger and Leopard, which makes testing easier. But it might behave consistently incorrectly due to the bugs. Check the various Leopard release notes for specifics. I'm afraid I don't understand this comment. What do you mean "..behave consistently incorrectly due to the bugs.."? Can you refer me to a specific item you might be thinking of here? So in sum, I think what you are saying is: Stick w/ 10.4 SDK as the safest path. However there might be bug fixes which you could benefit from by using the 10.5 SDK. To determine whether or not you actually do benefit from 10.5 means you have to learn more about it by reading the Release Notes. Does that sound right? So based on this reading of your comments and a few minutes with the XCode documentation I scan the AppKit Release Notes for Leopard and find the following: NSCompoundPredicate For applications linked on Mac OS X 10.5 "Leopard" or later, initializing an NSCompoundPredicate now copies the subpredicates array rather than retaining it. Applications linked on Mac OS X 10.4 "Tiger" continue to only retain the subpredicates array for binary compatibility. Well this appears germane to my application as I do use compound predicates. Judging by the scope the Release Notes and the speed with which I could locate even one germane issue I am convinced that my original instinct to use the 10.5 SDK because the code base is better IS correct. But I am puzzled by your "good and bad thing" comment...

Also, what do you mean "the underlying code is cleaner"? You are linking against the frameworks dynamically. You get the framework for the OS on which you're running. Regardless of what SDK you link against at build time, you're still linking against the libraries of your runtime environment. In general, your choice of SDK should be dictated by the latest features you want to use. If you don't want to use any 10.5-or- later-only features, sticking with the 10.4 SDK is safest. The reason is that the compiler will warn you if you accidentally slip up and make use of a newer feature. If you want to make use of 10.5 features but still deploy to 10.4, you have to take extra care. That's why it's not good to do so accidentally. You need to conditionalize all uses of 10.5 f
Re: 10.4 v. 10.5 SDK question
Ken; Once again, thanks for the exemplary response! (You are a great resource for the Cocoa community!) So... while yes, the 10.5 SDK does have bug fixes, using it and deploying to 10.4 potentially bifurcates the product into different behaviors. (It is really tough to determine where and when these differences might show up but the possibility exists -.> maddening from a support perspective) Since my goal was to deploy to 10.4 all along, by using the 10.4 SDK, the app will behave the same on both 10.4 and 10.5 (and 10.6) --> simpler from a support perspective. In some cases the behavior might be consistently wrong perhaps but any such incorrectness can be cured on both OSes by the same workaround -- > simpler development and testing Simpler development, simpler code, simpler testing, simpler support - yeah! Thanks for helping me better understand and for keeping my life simple!

I mean that, where there's a bug, an application linked against the 10.4 SDK will continue to get the buggy behavior from the framework, even when running on Leopard. Consistency. Whatever workaround you have for the bug will continue to work correctly on Leopard. If you link against the 10.5 SDK, then the application will get one kind of behavior when running on Tiger and get a different behavior when running on Leopard. Inconsistency. Any workaround for the Tiger bug may cause trouble when running on Leopard, but failure to work around the bug will cause trouble when running on Tiger. You have to write your code with this in mind, and you have to test both possibilities. Can you refer me to a specific item you might be thinking of here? Well, any of the bugs fixes listed in the release notes which note that the new behavior only occurs for applications linked against 10.5. For example, in the AppKit release notes, see the item titled "KeyValueObserving notifications for IBOutlets during Nib loading". Consider how easy it would be to unwittingly code an application that relies either on the old behavior which would break with the new behavior, or vice versa. So in sum, I think what you are saying is: Stick w/ 10.4 SDK as the safest path. However there might be bug fixes which you could benefit from by using the 10.5 SDK.

Well, consider this: if the bug fix were purely good, why would Apple maintain backward compatibility for apps which are linked against the 10.4 SDK? And remember, if you link against the 10.5 SDK but support deployment on 10.4, then you still have to cope with the case where NSCompoundPredicate merely retains rather than copying its subpredicates array, because that's what will happen when it's run on 10.4. So, your code has to be safe under both behaviors rather than just having one behavior to worry about.

Sizing table columns to fit data - a solution looking for suggestions
Folks;
iTunes and Excel both have a feature wherein if you double-click on
the column divider in the tableHeader then the table column width is
adjusted to the maximum width of the data in the column.
Below is a reasonably generic Cocoa solution for implementing this
behavior.
The tableView I developed this for uses an arrayController with
individual column bindings; not the old school -dataSource methods for
handling the data.
This code should exist in tableView's delegate.
This solution handles both strings and images.
I don't like the reliance on calling the arrayController directly but
for now it serves my purpose
I am interested in both criticisms and improvements - both will serve
the Cocoa community..
- (void)tableView:(NSTableView *)tableView
mouseDownInHeaderOfTableColumn:(NSTableColumn *)tableColumn {
NSEvent *event = [NSApp currentEvent];
if ([event clickCount]==2) {
NSPoint location = [event locationInWindow];
NSTableHeaderView *header = [tableView headerView];
location = [header convertPoint:location fromView:nil];
if (location.x>=2.0) location.x-=2; // offset point 2 pixels 'cause
the 'split' cursor is a little 'permissive'
NSTableColumn *thisColumn = [[tableView tableColumns] objectAtIndex:
[header columnAtPoint:location]];
NSString *maxStr = @"";
id thisObj;
NSCell *dCell;
float newWidth, maxStringWidth = 0.0 ,maxImageWidth = 0.0;
// me don't like the next line
NSArray *theValues = [[myArrayController arrangedObjects]
valueForKey:[thisColumn identifier]]; //dump the tableColumn values
to an array
if ((theValues!=nil) && ([theValues count]>0)) {
NSEnumerator *valEnum = [theValues objectEnumerator];
// find the longest string or widest image
while ((thisObj = [valEnum nextObject]) != nil) {
if ([thisObj isKindOfClass:[NSString class]]) {
if ([thisObj length] > [maxStr length]) maxStr = thisObj; //
keep the string 'cause later we use dataCell to get -width
} else if ([thisObj isKindOfClass:[NSImage
class]]) {
if ([thisObj size].width > maxImageWidth) maxImageWidth =
[thisObj size].width;
}

Re: Sizing table columns to fit data - a solution looking for suggestions
Corbin;
Hey thanks for replying!
First off, don't use the 'tableView:' prefix for your own delegate
methods. Consider what would happen if AppKit introduced the same
delegate method in a future release. Well, I can tell you from
experience that it won't be good. So, please make it something like
"scTableView:...".
This method is an existing method provided by NSObject from Apple! I
didn't make the name up, I used an already existing delegate mechanism.
Am I not understanding your point?
Use CGFloat not float.
OK, but why?
Setting the width in a loop is not good for performance; it might
cause the table to relayout a lot of times.
The code you cited is NOT inside a loop!?? Or am I not understanding
how something works?
NSCell *cell = [tableView preparedCellAtRow:i column:column];
10.5 Only -- I wanted a 10.4 compatible solution. I didn't say that
and I should have.
Thanks,
Steve

Below is a reasonably generic Cocoa solution for implementing this
behavior.
The tableView I developed this for uses an arrayController with
individual column bindings; not the old school -dataSource methods
for handling the data.
This code should exist in tableView's delegate.
This solution handles both strings and images.
I don't like the reliance on calling the arrayController directly
but for now it serves my purpose
Overall, I would do it slightly differently; I would subclass
NSTAbleHeaderView, figure out what column needs it to be autoresized
and when (ie: double click), and then ask the delegate (optionally)
what size it wants. But, I would make a default implementation based
on -cellSize (possibly doing a monte carlo simulation on the number
of rows, if there were a lot of rows, to help with performance).
Here are comments on your version:
I am interested in both criticisms and improvements - both will
serve the Cocoa community..
- (void)tableView:(NSTableView *)tableView
mouseDownInHeaderOfTableColumn:(NSTableColumn *)tableColumn {
NSEvent *event = [NSApp currentEvent];
if ([event clickCount]==2) {
NSPoint location = [event locationInWindow];
NSTableHeaderView *header = [tableView headerView];
location = [header convertPoint:location fromView:nil];
if (location.x>=2.0) location.x-=2; // offset point 2 pixels
'cause the 'split' cursor is a little 'permissive'
NSTableColumn *thisColumn = [[tableView tableColumns]
objectAtIndex:[header columnAtPoint:location]];
NSString *maxStr = @"";
id thisObj;
NSCell *dCell;
float newWidth, maxStringWidth = 0.0 ,maxImageWidth = 0.0;
Use CGFloat not float.
// me don't like the next line
NSArray *theValues = [[myArrayController arrangedObjects]
valueForKey:[thisColumn identifier]]; //dump the tableColumn
values to an array
Instead of this hardcoded access, do this (sorry, not complete, but
you should understand the idea):
CGFloat maxWidth = 0;
for (NSInteger i = 0; i < tableView.numberOfRows; i++) {
NSCell *cell = [tableView preparedCellAtRow:i column:column];
NSSize size = [cell cellSize];
if (size.width > maxWidth) maxWidth = size.width;
}
[tableColumn setWidth:maxWidth];
The code above is *much* more generic. Note that it doesn't consider
the indentation for outlineviews.
if ([thisColumn width] != newWidth) {
[thisColumn setWidth:newWidth];
Setting the width in a loop is not good for performance; it might
cause the table to relayout a lot of times.
Anyways, as usual, it never hurts to log feature requests for AppKit
to do this for you.

NSService - I need a headslap
Folks;
I have a need for a stand-alone service.
Seems like Service don't get alot of love... (Maybe that's my
problem .. but I don't think so)
To be clear here, this is a stand-alone .service type application (not
a service vended by a larger app (like Mail).
Here's what I have done:
0) built with a .service wrapper
1) Info.plist - PrinClass=NSApp; Bundle OS Type = APPL;
ExecutableFile=MyClassName; App is BackgroundOnly
1) Info.plist - Services{Menu, SendType, instance method name, and
incoming service port name)
2) No xib file
3) standard main.m
4) I have a single ObjC class whose .m looks like this
+(void)initialize { [NSApp setDelegate:self]; }
- (void) applicationDidFinishLaunching:(NSNotification *)aNote {
[NSApp setServicesProvider:self];
void NSUpdateDynamicServices(void);
}
- (void) myServiceName:(NSPasteboard *)pboard userData:(NSString
*)userData error:(NSString **)error {
.
}
What I can't get my head wrapped around is how/when does this .service
thing get launched?
The docs seem to indicate that you can just build it as a .service,
stuff into the ~/Library/Services and you are good to go...
(These docs are more than 8 years old Is there any later material?)
On Tiger systems I see the service appear on the Services menu
Not so on Leopard
(On Leopard even if I log out and back in I still do not see the
service in the menu...
But either way I never get any response. If I put in log statements I
never see any activity...
What am I overlooking? I KNOW its something silly but have mercy my
head is bloody
Thanks for any help!!

Re: NSService - I need a headslap
Well, sheesh - that's embarrassing! There is no 'self' until init -
I know that! Ugh.
However, that doesn't change my end result!
I never see anything on the Services menu nor anything from the NSLog
statements shown below.
(Even when I double-click on the .service file; after whcih I CAN see
it in the process list in Activity monitor but still no log messages)
Logging out and back in doesn't make my service name appear on the
Service menu...
This is on a 10.5.6 system using a Release build which has been placed
in ~/Library/Services.
SO my basic questions still stand:
What event/conditions launches a .service which resides in ~/Library/
Services?
Should/must .service files be 'Background Only'?
Am I missing something basic in my setup here -
I have only a Info.plist and 1 .h (NSObject) and 2 . m files (main and
MyService) and no .xib?
Other than the 'wrapper' settings are there other compiler settings
required for this setup?
I have only 2 steps in my build process: 'Compile Source (2)' and
'Link Binary w/ Lib (1)' [Cocoa]
To me it feels like there is something basic about the application
package that is not right but then I can't seem to keep 'self'
straight either...
MyService.m
-(id) init {
[super init];
NSLog(@"*[%@ %...@]",[self class],NSStringFromSelector(_cmd));
[NSApp setDelegate:self];
return self;
}
- (void) applicationDidFinishLaunching:(NSNotification *)aNote {

void NSUpdateDynamicServices(void);

Re: NSService - I need a headslap
Peter;
Thanks for the response!
Launched on demand based on the Service specifications in Info.plist
- there that's a big conceptual milestone! Thank-you!!
(I wish that was written down somewhere I could find...)
So for a stand-alone service should we -terminate after each call?
Here's how I'm installing the .service:
servicesFolderPath =
[[NSSearchPathForDirectoriesInDomains(NSLibraryDirectory,
NSUserDomainMask, YES) objectAtIndex:0]
stringByAppendingPathComponent:@"Services"];
if (![fileManager fileExistsAtPath:servicesFolderPath]) {
[fileManager createDirectoryAtPath:servicesFolderPath
attributes:nil];
}
srcPath = [[NSBundle bundleForClass:[self class]]
pathForResource:@"MyService" ofType:@"service"];
destPath = [servicesFolderPath
stringByAppendingPathComponent:@"MyService.service"];
if ( ([fileManager fileExistsAtPath:srcPath]) && (![fileManager
fileExistsAtPath:destPath]) ) {
[fileManager copyPath:srcPath toPath:destPath handler:nil];
NSUpdateDynamicServices();
} else {
if (![fileManager fileExistsAtPath:srcPath]) {
_WDIfV NSLog(@"MyService.service - Payload Not
Located.");
} else {
_WDIfV NSLog(@"MyService.service was already
installed.");
}
}
Nothing appears in the Service menu on Leopard EVER, even after re-
logging in.
What I observe is that on Tiger, after installing as above, the next
time I launch any application its Service menu DOES include my item...

Re: NSService - I need a headslap
Peter;
I think I may have found into the core issue for me:
I don't have a xib file in this stand-alone app.
In main.m the invocation of NSApplicationMain() is equivalent to:
void NSApplicationMain(int argc, char *argv[]) {
[NSApplication sharedApplication];
[NSBundle loadNibNamed:@"myMain" owner:NSApp];
[NSApp run];
}
As you can see from my Info.plist sent earlier I don’t have ‘Main nib
file base name’ set.
Could this cause the whole app to just go plunk?
Would I need to subclass NSApplication instead of NSObject here?
(Yikes that sound BIG?) (I’d need to switch out Principal Class in
Info.plist to be MyService, yes?)
What would main.m need to look like then?
int main(int argc, char *argv[])
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
freopen([[NSHomeDirectory() stringByAppendingPathComponent:@"Library/
Logs/com.myCompany.MyService.log"] fileSystemRepresentation], "w",
stderr);
[pool release];
[MyService sharedApplication];
return [NSApp run];
}
I’m willing to bet that the above is NOT right!
On the whole would it just be easier to add a xib with nothing in it?
Seems kinda wonky
My gut tells me that this is where I am going wroing!

Re: NSService - I need a headslap (A Solution)
Peter;
Turns out my issue was not related to the Info.plist at all.
The confusion about 'default' label on the 'Services' menu has to do
with how Finder handles dropping a .plist into .txt field...
My service 'MyService' does indeed need to subclass NSApplication.
I just quit fighting against the tide and added an empty nib. -- Presto!
So now my working stand alone service provider consists of merely 6
small items:
1) an .icns file
2) an empty IB generated nib file - completely unmodified (v2 NIB in
my case [Tiger compatible])
(adding a NIB allows me to just use the standard main.m 'return
NSApplicationMain(argc, (const char **) argv);'
3) main.m - the usual Cocoa version (however see question below)
3) an Info.plist (Principal class set to 'MyService' and the standard
'Services' specification.
4) a MyService.h file which sublclasses NSApplication
5) the MyService.m file for the file above. This does 3 things:
- in init [NSApp setDelegate:self];
- in 'AppDidFinishLaunch' [NSApp setServiceProvider:self];
- provides the required method(s) for providing a service:
- (void) seviceName:(NSPasteboard *)pboard userData:(NSString
*)userData error:(NSString **)error
*** 2 Questions
-- I am operating on the presumption that this standalone service
should terminate after providing its service but I can see an argument
for not doing so.
It's pretty lightweight (one class (~100 lines of ObjC) and an empty
nib).
Do you have any guidance to offer here.
Since there is no interface to this service, what is the standard UI
support for termination?
-- In the past, I have used the following main.m to log data to
specific files:
int main(int argc, char *argv[]) {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
freopen([[NSHomeDirectory() stringByAppendingPathComponent:@"Library/
Logs/com.mycompany.myapp.log"] fileSystemRepresentation], "w", stderr);
[pool release];
return NSApplicationMain(argc, (const char **) argv);
}
But here my log statements are ending up in the console log.
Is there a way I can easily route log statements in MyService to a
specific file?
Hope to get some feedback on these questions and that this posting
eventually proves useful to someone else.

The key here needs to be "default" instead of "Menu item title".
This is a dictionary because it used to be keyed by localization,
with "default" the value for an unknown loc. Now we use the
ServicesMenu.strings file for localization, but the dictionary
remains.

Warning 'could not find object file' on NSAppleScript -executeAndReturnError
Folks;
I use AppleScript to accomplish some inter-application tasks.
Over time I have a developed several utility routines in Cocoa, one of
which is to return the results of an arbitrary script execution. as an
NSString:
- (NSString *) getStringResutlFromAppleScript:(NSString *)theScript {
NSDictionary *errorDict = nil;
NSAppleScript *appleScriptObject = [[NSAppleScript alloc]
initWithSource:theScript];
NSAppleEventDescriptor *eventDescriptor = [appleScriptObject
executeAndReturnError: &errorDict]; \\this compiles on-the-fly if
necessary
[appleScriptObject release];
if (([eventDescriptor descriptorType]) && (errorDict==nil)) {
return [self stringFromAppleEventDescriptor:eventDescriptor];
} else {
NSLog(@"ERROR: ",theScript);
...
This has been working for quite some time.
But now I have recently noticed that every execution of the
'executeAndReturnError:' is causing a entry in the console:
warning: Could not find object file "/Developer/usr/lib/gcc/i686-apple-
darwin9/4.0.1/libgcc.a(_eprintf.o)" - no debug information available
for "/var/tmp/gcc/gcc-5465~16/src/gcc/libgcc2.c".
I've stepped thru numerous examples and it is ALWAYS this line. The
scripts are all valid scripts.
The code executes properly but it just sticks in my craw...
What have a not got configured correctly?
Thanks!

Re: NSToolbarItems - deallocating view-based items
Peter; Thanks for the reply but . The documentation for NSToolbarItem for =setView says: "...The view for the receiver. The view and all of its contents must conform to the NSCoding protocol if the toolbar supports customization" There is no further discussion in the documentation. One of the my view based items is just a simple NSSearchField. NSSearchfield DOES conform to NSCoding. Is it clarified anywhere in the documentation what else is necessary to successfully customize a view based toolbar item? I have declared the instance variable as an IBOutlet: IBOutlet NSSearchField *searchFieldOutlet; (I need the IBOutlets to fully utilize the toolbar item. functionality in my controller code) I have hooked this up in the usual way inside IB. I just do not understand what you mean by "fresh". Are you saying that I must instantiate them in code? ([... alloc] init]) How do I hook this code instance as an IBOutlet? Do I release after the "- itemForItemIdentifier:willBeInsertedIntoToolbar:" method I have more complex views than a single NSSearchField, how do I deal with them? Is the end result that you cannot use IB built view based toolbar items if you intend to allow customization; that you must build the entire view in code? Could you explain just a bit more?

Cocoa <- > PHP <-> MySQL
Folks; I've inherited some Cocoa code that uses NSMutableNURLRequest and NSURLConnection to pass .php request to a server. The NSMutableURLRequest packs up some data into the the .php which stuffs this data into a MySQL database. This is all working nicely. Now what I've been asked to make happen is to submit a different bit of php which will run a query against this same MySQL database. We want to use Cocoa to submit the php script and retrieve the response, which will be the results of the query. Setting aside the php on the server side, I'm hoping to find a working example of something similar to the Cocoa piece of this new requirement. I'm just looking for how to 'submit', wait for response, capture the response / error in Cocoa. I'll get the server side figured out separately Thanks for any pointers!

NSTextView won't allow a Return (Enter)
Folks; I'm really puzzled by this one. In one window I have a TexView inside a ScrollView - works well - user can type many lines and scroller appear and disappear as expected. In another window I have another TextView inside a ScrollView and every time the user hits the 'Return' or 'Enter' I get what is shown below. What is making the TextView give up being first responder? I can't see any difference in the IB settings... The 'offending' textView accepts the cursor normally and as long as the user does not use the 'Enter/Return' all is well. When that key is struck then the cursor disappears. A set of 'Tab's will bring the cursor back cycling through the various fields on the window. I know this is probably one of those 'Duh' issues but I evidently need the whack on the head to see it Thanks for the tap, Steve #2 0x90837e94 in _NSSetObjectValueAndNotify #3 0x907d9cee in -[NSObject(NSKeyValueCoding) setValue:forKey:] #4 0x9085e7c1 in -[NSObject(NSKeyValueCoding) setValue:forKeyPath:] #5 0x9194c441 in -[NSBinder _setValue:forKeyPath:ofObject:mode:validateImmediately:raisesForNotApplicableKeys:error :] #6 0x9194c1f2 in -[NSBinder setValue:forBinding:error:] #7 0x9194be8b in -[NSValueBinder _applyObjectValue:forBinding:canRecoverFromErrors:handleErrors:typeOfAlert:discardEditingCallback:otherCallback:callbackContextInfo:didRunAlert :] #8 0x9194bb19 in -[NSValueBinder applyDisplayedValueHandleErrors:typeOfAlert:canRecoverFromErrors:discardEditingCallback:otherCallback:callbackContextInfo:didRunAlert :] #9 0x9194e86e in -[NSValueBinder _applyDisplayedValueIfHasUncommittedChangesWithHandleErrors:typeOfAlert:discardEditingCallback:otherCallback:callbackContextInfo:didRunAlert :] #10 0x9194b3fa in -[NSValueBinder validateAndCommitValueInEditor:editingIsEnding:errorUserInterfaceHandled :] #11 0x9194b1b7 in -[_NSBindingAdaptor _validateAndCommitValueInEditor:editingIsEnding:errorUserInterfaceHandled:bindingAdaptor :] #12 0x9194b0ef in -[_NSBindingAdaptor validateAndCommitValueInEditor:editingIsEnding:errorUserInterfaceHandled :] #13 0x9181da6d in -[NSTextView(NSSharing) resignFirstResponder] #14 0x91793b0d in -[NSWindow makeFirstResponder:] #15 0x9181d628 in -[NSTextView(NSPrivate) _giveUpFirstResponder:] #16 0x9181d4df in -[NSTextView(NSKeyBindingCommands) insertNewline:] #17 0x9181d281 in -[NSResponder doCommandBySelector:] #18 0x9181d108 in -[NSTextView doCommandBySelector:] #19 0x91810229 in - [NSKeyBindingManager(NSKeyBindingManager_MultiClients) interpretEventAsCommand:forClient:] #20 0x9180ee36 in -[NSTSMInputContext interpretKeyEvents:] #21 0x9180e952 in -[NSView interpretKeyEvents:] #22 0x9180e862 in -[NSTextView keyDown:] #23 0x9177eddd in -[NSWindow sendEvent:] #24 0x9174ad49 in -[NSApplication sendEvent:] #25 0x916a869f in -[NSApplication run] #26 0x916758a4 in NSApplicationMain ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: NSTextView won't allow a Return (Enter)
Folks; Sheepish - the offending textView was set as field Editor Yeesh I guess I need some sleep. Thanks for the responses!

Double Initialize - is that how it should be?
Folks;
I use an object in my application called 'appDelegate'; it's a
subclass of NSObject.
I instantiate this object in the main Nib file
This object has IBActions for the main menu and since it is -app
delegate it is a kind on central dispatcher.
My question is this:
The +initialize is run twice when the app loads:
2009-03-16 20:21:42.690 XYZ[6676:813] *[AppDelegate initialize]
2009-03-16 20:21:42.781 XYZ[6676:813] *[NSKVONotifying_AppDelegate
initialize]
Once for the object itself and then again as the instance in the Nib.
That's how I read this. Is that wrong?
So I wonder if this is wasteful. I don't really want to run
initialize twice.
It kind of torques my notion of a class that +initialize is run twice
but I try and just play along
I don't see how to use this IBActions and IBOutlets without
instantiating.
Is the correct thing to do here break this object into smaller objects?
Thanks for any clarifying comments
Steve

What is the console trying to tell me?
Folks; I have an 10.5 Intel development environment but I am deploying to 10.4 Universal using the 10.4 SDK. I have a QTMovieView object from IB in a window. When I run in Debug mode a message appears in the Console. When I run in Release mode on either platform - no message appears (I route stderr to a logfile) Everything works fine, Debug and Release; I would just like to know what I am trying to be told! Here's the gist of the message: shlibs-removed,shlib-info=[num="103",name="AudioIPCPlugIn" shlibs-removed,shlib-info=[num="104",name="AppleHDAHALPlugIn" Thanks!
