I've always wondered if I insert a managed object, then later fetch it

Yes, basically. There is only going to be one in-memory object at a time
that represents the same managed object.
It certainly seems to be sensible, but I just wish someone could find such
documentation. I can't.
Every NSManagedObjectContext holds its own but unique copy of your object.
In the last few minutes here, I improved my demo to test an sqlite store as
well as an in-memory store, and also I setStalenessInterval to 0 and threw in
some -refreshObject:mergeChanges:NO and more saves. The only difference I
found was that, while the in-memory store fetches the same object that you
inserted, the sqlite store does not, although subsequent fetches return the
same object.
This is because the object in the sql-store needs a primary key. As long as it
was not saved it has a temporary key only. When saved it gets a persistent key.
After that it is identifiable by this and therefore you get alwas the same
object back.
I would have thought that your inserted object gets the persistent key set and
will therefore be the same object as the fetched ones. But I did not check your
code for a misconfiguration.
Can anyone guarantee this?
I would imagine that, even though it's not documented, Apple must realize
that if they were ever to change this behavior, it would probably break alot
of apps which have been relying on it without the designers realizing this.
Would Apple ever ever do anything like that?
No, you will always get the same object. Because this was why CoreData and EOF
where made for. Exactly this.

Re: iPhone: badge icon for a button in toolbar
Awesome - thank you!
Now I am looking at how to access a certain UIBarButtonItem so I can set
it's badge.
In my app delegate I have a UITabBarController. In IB I can't seem to create
an IBOutlet and wire the button I want up so I can set it's badge string.
When I attempt to wire it up from File's Owner (MainWindow.xib), I only have
the option Outlets -delegate.
- (void)applicationDidFinishLaunching:(UIApplication *)application {
*// Add the tab bar controller's current view as a subview of the window
*
[window addSubview:tabBarController.view];
How do I access the button I want from the appDelegate?

Re: iPhone: badge icon for a button in toolbar
add UIBarButtonItem outlets to whatever class Files Owner is
eg
@property( readwrite, retain ) IBOutlet UIBarButtonItem *item1;
then you will be able to hook them up in IB.

iPhone and OS X apps question
I am looking at prototyping something and would like an iPhone app to be able to talk with a desktop OS X app. Do something on the iPhone app, it's reflected in the OS X application. And vice-versa.

Re: iPhone and OS X apps question
Hey Eric! Over what timeframe did you want the iPhone app and the desktop app to be in sync? Immediately? ASAP? When iPhone is tether sync'd? Something else? Is this one iPhone app to one desktop, all with the same user? Or is this many to many with many users? Something inbetween? What behaviour do you envision when one or the other app is working 'offline' , say on an airplane or in the metro? And, of course, the fun question... Who wins when there's a conflicting update? ;-) Food for thought! M. Sent from my iPhone On 2010-02-11, at 8:29, Eric E.

Re: iPhone and OS X apps question
I would begin with Apple's picture-sharing sample code. I think that sample has two parts - server and client. Ther is also an iPhone sample dealing with locating Bonjour services. Basically Bonjour is used to have the server (Mac app) and client (iPhone) discover each other. Then use whatever networking protocol you want to send data. This setup works extremely well in the simulator. When working with real hardware you will need to connect it (and your Mac) to the same wifi network. There is currently no public APIs to talk to a docked iPhone OS device. Sent from my iPhone On Feb 11, 2010, at 10:29 AM, Eric E.

Re: What classes have -init?
It's unfortunate that all initializers don't at least call init internally. That would make subclassing easier if all one needs is to set a few ivars. In the earlier days of MacApp (Pascal and first C++ versions) there was a basic initializer, similar to init, called by all classes, just for that purpose. Of course, Objective C at least sets them all to zero, reducing the need -- but it still would have been useful, sometimes eliminating the need to override multiple initializers. Of course, you can always override init first, just to test whether it gets called. But then, there's no guarantee in future versions. True. But most classes have designated initializers that configure the class properly. They should be documented, although typically they‚re used for subclassing the class.

Re: iPhone and OS X apps question
To clarify what I'm looking to do... I have a wifi router attached to the back of my Mac. My Touch connects to that router. I'd like to run an app on the Touch and an app on the Mac. I'd like to be able to send a simple string from either app to the other and acknowledge receipt of that. Swipe on the Touch, the Mac app's UI displays got the swipe - and press a button or something on the Mac and it tells the Touch app got the button Once I get communication going, I plan on making the behaviors more interesting. ASAP as far as timing goes. It's not for a real world product, just prototyping for an idea. I have no experience with Bonjour or sockets on this platform... could I open sockets in each app and then have them talk that way? If yes, is there sample code someplace that basically does this? The Touch app could talk to a Flash app running on the Mac too - doesn't need to be a OS X application.

It's worthwhile keeping this in mind: http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/CocoaFundamentals/CocoaObjects/CocoaObjects.html#//apple_ref/doc/uid/TP40002974-CH4-SW3 Particularly: When you define a subclass you must be able to identify the designated initializer of the superclass and invoke it in your subclass’s designated initializer through a message to super. You must also make sure that inherited initializers are covered in some way. Applying that [conceptually] to NSArray, say, there's no actual luck involved. If 'init' is a designated initializer, it should be documented in the class reference and there's no problem. If not, then NSArray *must* ensure that calling it results in one of its real designated initializers being called, *or* must produce an error. If it produces an error that I'm not expecting, that would be bad. What I was wondering was how I knew whether it would produce an error, other than by just testing on every version of the OS that I care about. In a previous reply, Henry McGilton pointed out that the NSObject documentation states that its implementation of init does not produce an error.

Re: What classes have -init?
My point was that if you could count on init being called internally and all you needed was to initialize some ivars, you could override init and not have to override the (sometimes more involved) designated initializer and possibly other initializers. You could still use the (superclass) designated initializer or a class-level instantiator without overriding it. This relates to a long ago discussion about the fact that class-level instantiators, e.g., [someClass someClassWithMoreStuff], should (and I think do) always use the class designation self so that they always instantiated the subclass object and not the superclass object.

Re: iPhone: UIWebView not displaying until scrolled?
I fixed it - the problem lies when the UIWebView is loaded, but it's not on
screen - it's center is off screen. When I animate it into view on the
Touch, it's blank until I scroll it a little. Now, before I call my
animation, I have the webView reload, then its' animated into view and it
works.

maybe that is some different issue that somehow became apparent on

Re: NSXML and
For the sake of the archives, and in case anyone else comes across this problem
(anyone using the NSXML classes should at least be aware of it), here is the
workaround I have settled on.
I have created my own NSXMLDocument category to generate NSData using
-XMLDataWithOptions: that then escapes any potentially dodgy occurrences of ‘’
by loading that data object into an NSString. Here is the category method:
@implementation NSXMLDocument (BugWorkaround)
/*
*NOTE: This method works around a bug in the Cocoa NSXML classes, which refuse
to escape '' in any situation.
*According to section 2.4 of the XML specs (
http://www.w3.org/TR/REC-xml/#syntax ), '' and '' must always
*be escaped, but '' only needs escaping when it appears in the character
sequence ']]', unless it marks the
*end of a CDATA block (or a conditional section - see section 3.4). The Cocoa
NSXML classes correctly escape
*'' and '' to 'lt;' and 'amp;', but *never* escape '', even when it
appears in the string ']]' inside an
*element's -stringValue. This generates invalid XML, and NSXMLDocument will
refuse to read invalid XML unless
*NSXMLDocumentTidyXML is set, but that messes up all the white space.
*This method therefore generates NSData from the NSXMLDocument, then reads
that data into an NSString. It then
*looks for the ']]' sequence. If it finds it, it looks for the '!['
sequence, which opens a conditional section
*or CDATA block. If '![' is *not* found in the XML string, then we can safely
assume that any occurrences of
*']]' must appear only in places where it should be escaped to ']]gt;' in
order to create valid XML. This method
*replaces such instances with an escaped version of the string.
*/
- (NSData *)XMLDataWithPrettyPrintAndExtraEscapes
{
// First, get the data.
NSData*data = [selfXMLDataWithOptions:NSXMLNodePrettyPrint];
// Then, read the resulting XML string.
NSMutableString*str = [[NSMutableStringalloc] initWithData:data
encoding:NSUTF8StringEncoding];
// Does this XML contain the character sequence ']]'?
// If not, do nothing - just return the data as-is, as the NSXML classes
// will have escaped everything that needed escaping.
NSRange range = [str rangeOfString:@]]];
if (range.length == 0)
{
[str release];
return data;
}
// If it does contain these characters, though, we need to do some checks. This
sequence
// of characters should only appear at the end of a CDATA or conditional
sequence. If the ']]'
// string appears anywhere else - i.e. in content - then the '' *must* be
escaped to 'gt;'.

'![CDATA[...]]'.).

our purposes.

// so we replace all of the occurrences of this string with the correct
']]gt;' escaped version, and then
// generate and return our own data object from our string.

[str length]-range.location)];
data = [str dataUsingEncoding:NSUTF8StringEncoding];
[str release];

}
@end
I’ve also filed this as a bug - #7637981.
--- ORIGINAL MESSAGE ---
Still working on this and still getting nowhere, so another question:
Is there a way to prevent NSXMLElement converting '' into 'amp' so that I can
resolve character entities myself in my own NSXMLElement category -init...
method?
To recap the problem, the NSXML classes change '' into 'lt;' and '' into
'amp;' (when in string value content), just as they should according to the
XML specs. But they don't convert '' into 'gt;'. This is fine as the XML
specs don't require this in most situations, but if '' appears in the string
']]' (when not ending CDATA) then it must be escaped - but Apple's NSXML
classes don't do this, generating invalid XML that cannot be opened by
NSXMLDocument in this situation.
I tried creating my own -initWithName:validStringValue: method which did some
jiggery-pokery and then called -initWithXMLString:, thinking that this wouldn't
do any conversion, the idea being that I could force ']]' to appear as
']]gt;' myself by creating the XML string directly rather than going through
-setStringValue. But no. If you try this:
NSXMLElement *element =

Views and Layers share the same geometric ordering, that is what a view draws over is dependent on the order of its corresponding layer. Your effectively adding your gradient layer after all of the other view's that your view controller loaded, thus it is drawing over the other views and their subviews/layers. You need to either insert the gradient layer into the sublayers array first, or move the views that should be on top to after. You may also want to consider creating a UIView subclass that returns [CAGradientLayer class] from its +layerClass method and exports methods to configure the gradient layer, then you can do your layout in IB (although you would still need to configure it in code). -- David Duncan Apple DTS Animation and Printing ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: What classes have -init?
I have read it. My point was that if all Cocoa classes called init somewhere in their other initializers (or had a two-step initialization similar to what MacApp did), then you could simply override (not call) init for simple ivar initialization in a subclass, which would in no way interfere with a designated initializer. Since they don't all call it, it's really academic.

Trying to simulate a NSScrollView within a NSView
Hi, I am trying to emulate a scrolling behavior within a NSView. I am calling scrollRect:by: and as the documentation specifies: -- Discussion This method is useful during scrolling or translation of the coordinate system to efficiently move as much of the receiver’s rendered image as possible without requiring it to be redrawn, following these steps: • Invoke scrollRect:by: to copy the rendered image. • Move the view object’s origin or scroll it within its superview. • Calculate the newly exposed rectangles and invoke either setNeedsDisplay: or setNeedsDisplayInRect: to draw them. You should rarely need to use this method, however. The scrollPoint:, scrollRectToVisible:, and autoscroll: methods automatically perform optimized scrolling. (cf. http://developer.apple.com/mac/library/documentation/Cocoa/Reference/ApplicationKit/Classes/NSView_Class/Reference/NSView.html ) -- The scrolling (step 1) looks fine but I don't really get how to set the origin. My goal is to only redraw the updated areas (top or bottom). I use Quartz Debug to visualize the updated areas. I tried using setBounds: but it redraws everything. A small project can be found here: http://files.me.com/ffreling/4oa6n8 (I set the NSImageView to an image from my desktop for the example, you can remove it or set it to another image if you want) Any help would be appreciate :) Thank you.

Re: Creating an Application Support folder
Hi Paul Firstly, are you using the NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES); function to find the application support folder? That would get you the base path, then you can use the stringByAppendingPathComponent: method to add your folder name, then BOOL isDirectory = NO; BOOL exists = [[NSFileManager defaultManager] fileExistsAtPath:errorReporterPath isDirectory:isDirectory]; and then check whether it exists, and whether it is a directory. Then you can use methods like: BOOL created = [[NSFileManager defaultManager] createDirectoryAtPath:path withIntermediateDirectories:YES attributes:nil error:error]; to create the necessary folders. Hope this helps. Gideon On 11/02/2010, at 1:44 PM, Paul Johnson wrote: I'm trying to find a best way to create the Application Support folder.

You could delete it, or you could just choose another name for your folder. Either way, NSFileManager has methods to do what you want. Renaming you can handle yourself - just keep renaming until you get a clear outcome that meets your needs (appending digits is a simple way). [NSFileManager fileExistsAtPath:isDirectory:] can tell you whether you're looking at a file or folder. For the rename situation, your -applicationSupportFolder method (why not make it a class method?) can do all the work internally to make sure that the folder is valid, belongs to you, created if necessary and so on, so clients of it can just use the method to work with the folder, safe in the knowledge that there's no more to do. Also, presumably you are returning the name of YOUR unique application support folder with the ~Library/Application Support directory. That folder can be found using NSApplicationSupportDirectory, then you usually will put your own folder inside this. If your folder uses your app's bundle identifier, it will almost certainly not collide with anyone else's. However, a much earlier discussion on that seemed to indicate that most people use the application name, which might not be quite so guaranteed to be unique. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Look for the function NSSearchPathForDirectoriesInDomains(). Pass the constant NSApplicationSupportDirectory. Consider which domains you want to cover. Heed the warning that the paths the function returns may not describe directories that exist yet.

Replacing model objects using an NSArrayController
Hello everyone,
I'm a bit of a newbie here, but hopefully this question won't be too annoying.
:-)
My application contains several records displayed to the user in an NSTableView
bound to an NSArrayController. Because these records are complicated
(containing around thirty fields), I have implemented an Edit option where the
user can select one of rows in the table, click the Edit button, and have a new
window appear displaying all of the fields, radio buttons, numeric values, etc.
for changing.
I have implemented NSCopying on my data objects. When I go to display the edit
window, I get a reference to the selected object (myController arrangedObjects
/ selectionIndexes / objectAtIndex), copy the data into a new object for
editing ([myObject copy]) and then pass that off to the NSWindowController that
manages the editing process. I do this so that a Cancel from the editor window
will not affect the original object.
All of that seems to be straightforward enough.
My question is how to get the new, edited object back into the array controller.
I have implemented all of the KVC methods in the Manager class that supplies
the data to the NSArrayController, and they are being called for Add and
Delete. I've also coded a replaceObjectInMyArrayAtIndex:withObject: which I
would like to be called by the array controller when it swaps in the new object
for the old one. Although my current code does the same thing with separate
remove and insert calls (see below), that seems to lead to two undoable
actions, rather than the one I have coded in
replaceObjectInMyArrayAtIndex:withObject:
fSrcbook = [selArray objectAtIndex: selItem];
fEditbook = [fSrcbook copy];
// display editing window, etc.
if (returnCode == NSOKButton) {
NSArray * bka = [fArrayController arrangedObjects];
int row = [bka indexOfObjectIdenticalTo: fSrcItem];
[fArrayController removeObject: fSrcItem];
[fArrayController insertObject: fEditItem
atArrangedObjectIndex: row];
}
(I suppose I could put the remove/insert in an undo edit group, but I'd like to
keep my undo code out of this method, if possible. No particular reason, except
that it feels cleaner to me.)
I can't see anything in the NSArrayController class that will help me do the
replace directly, and nothing else relevant has popped up in my searching for a
solution. I admit, however, that I am sometimes blind to the obvious, and I
also may have used inadequate search terms. Still, I highly doubt I'm the first
person to want to do this, and it just seems like it should be possible to do a
replace directly.
And I am also wondering if this is the usual way to implement editing a
complicated object like I am attempting to do.
Any suggestions or clarifications would be greatly appreciated.
Thank you,
Bill

--Graham
Not really; suppose you want to subclass some class that has two separate init
methods:
- (id)initWithFoo:(Foo *)foo;
- (id)initWithBar:(Bar *)bar;
and suppose you just want to set some initial internal state, which needs to
always be set the same way at init time no matter how the object is
initialized. Which init method do you override? It’s possible that the
“initWithFoo:” method may look like this:
- (id)initWithFoo:(Foo *)foo
{
return [self initWithBar:[SomeClass convertAFooToABarSomehow:foo]];
}
in which case you’d just need to override initWithBar:. However, what happens
if it’s actually the other way around, and initWithBar: looks like this:
- (id)initWithBar:(Bar *)bar
{
return [self initWithFoo:[SomeClass convertABarToAFooSomehow:bar]];
}
Knowing which is which requires you to have knowledge of the parent object’s
code. And what if the implementation of the parent changes over time from one
of the above scenarios to the other? Clearly the only way to make sure your
init *always* gets called is to override init, initWithFoo:, *and*
initWithBar:, and if there are more than just two initializers, this can get
quite cumbersome. And even then, what happens if the superclass gets updated so
that a third initializer gets added:
- (id)initWithBaz:(Baz *)baz;
which doesn’t happen to call initWithFoo: *or* initWithBar:? Now your custom
init won’t get called at all if that initializer is used.
Incidentally, there is just such a class in Cocoa: NSDocument. It provides six
different init methods:
- (id)init;
- (id)initForURL:(NSURL *)absoluteDocumentURL withContentsOfURL:(NSURL
*)absoluteDocumentContentsURLofType:(NSString *)typeName error:(NSError
**)outError;
- (id)initWithContentsOfURL:(NSURL *)absoluteURL ofType:(NSString *)typeName
error:(NSError **)outError;
- (id)initWithType:(NSString *)typeName error:(NSError **)outError;
- (id)initWithContentsOfFile:(NSString *)fileName ofType:(NSString *)docType;
- (id)initWithContentsOfURL:(NSURL *)aURL ofType:(NSString *)docType;
Yes, the last two of these are deprecated, but it’s still possible that they
could get called, so you’d still have to take that into account. Interestingly,
though, someone at Apple appears to agree with Gordon here, since all of those
NSDocument initializers actually seem to call -[self init] instead of -[super
init], with the result that you can in fact just override -init instead of
having to override all six methods separately (and the NSDocument subclass
template even includes an -init method, to further encourage this).

There isn't a replace method for an array controller. If you must do it as a
single operation, then solution would be to fetch the original object at the
end of editing, update its properties to match the (edited) properties of the
copy, then discard the now-temporary object copy.
However, your description doesn't completely make sense. There are no objects
in an array controller. Instead, think of the array controller as a sorted,
filtered perspective on your underlying data. Normally, the array controller is
monitoring the underlying data via KVO, so any underlying changes are noticed
and it adjusts itself accordingly without your writing any code.
You seem to be saying that you've already updated the underlying data model (I
have implemented all of the KVC methods in the Manager class ...), in which
case you *don't* want to mess with the array controller directly. Basically,
there are two approaches to adding, deleting and replacing, when an array
controller is involved:
1. Update the data model directly and KVO compliantly, and let the array
controller notice the changes via KVO.
2. Do not update the data model directly, but use the array controller methods
instead (removeObject:, insertObject:atArrangedObjectIndex:, etc). These
methods internally cause the data model to be updated.
Pick one. Not both.
Method #1 is the cleanest, because it doesn't introduce the array controller
(which is really part of your UI glue code) into the data model update, but you
*must* ensure that the data model change is made KVO compliantly. Typically,
that means making the changes using a mutableArrayValueForKey: proxy object.
Method #2 is a convenience when you've not built (or have not been able to
build) a clean MVC design into your app, or when you must work with the
arrangedObjects order for some reason.
Others will likely disagree with me, but I think that there's something a bit
smelly about code referring to array controllers. It often indicates a defect
in the MVC design.

It’s also the method that does most of the work, and the one that other initialization methods in the same class invoke. It’s a Cocoa convention that the designated initializer is always the method that allows the most freedom to determine the character of a new instance (usually this is the one with the most arguments, but not always).
