Hi all, I have the following code in a category on NSData:
@implementation NSData (SHA1Hash)
- (NSData*) sha1Hash
{
// calculates the 160 bit SHA-1 digest of the given data
unsigned char* digest = (unsigned char*) malloc(20);
SHA1([self bytes], [self length], digest);
return [[self class] dataWithBytesNoCopy:digest length:20];
}
@end
The static analyzer reports this:
Potential leak of an object allocated on line 622
Method returns an Objective-C object with a +1 retain count
(owning reference)
Object returned to caller as an owning reference (single retain
count transferred to caller)
Object allocated on line 622 is returned from a method whose
name ('sha1Hash') does not contain 'copy' or otherwise starts with 'new' or
'alloc'. This violatesthe naming convention rules given in
the Memory Management Guide for Cocoa (object leaked)
But I think this is wrong - [NSData dataWithBytesNoCopy] returns an object I
don't own, and it in turn takes ownership of digest. So where's the leak?
Is clang simply mistaking the fact that +dataWithBytesNoCopy CONTAINS 'copy'
and not STARTS WITH copy?

Re: Best practice example for a setup wizard?
Thanks for all the replies. I am inclined to agree - the last thing I want is to build something that looks like a Windows application! And I get the issue of not bugging the user with a tedious setup process. The idea of having preset values that the user can change if he wants to is the way to go, I'm sure. OK, perhaps I need to rethink how this works. Given that the underlying purpose is to authenticate the user to allow access to an encrypted database, would it make more sense for me to use the user's Mac OS X account credentials? Is there a way (I hesitate to use the phrase best practice again) for my program to authenticate the user that way?

Re: Problem printing offscreen PDFViews
Tried that already, and it only lead to other weird stuff. Consider
this: If PDFView obeyed all of the normal laws Cocoa printing,
wouldn't PDFView's printWithInfo:autoRotate: be unnecessary?
Not that this really matters anymore, since I ended up taking the long

now just curious as to why it didn't work.

iPhone: UITableView with cells of varying heights
I am pulling in an RSS feed, and each item has it's own summary of a varying amount of text. I am using a table and presently setting the height of each row the same to allow for the most text. This looks awful as some items have a lot of empty space for it's row. Is it possible to have a UILabel where I set numberOfLines = 0, set the width, and have the height of the label expand vertically to contain all of the text, and then use it's height to help determine the height the cell itself needs to be? The result would be a UITableView with rows of varying heights, perfectly framing each row's content. I was using a UIWebView to display the summary since it came with tons of html tags in it, but I've since just stripped all of the tags out of each item's summary.

Re: iCal-style NSTextFields
I've been working through this a bit more. To get bindings to work, I added
the following to my custom textfield:
if (!bindingsDict) {
self.stringValue = newStringValue;
}
if (bindingsDict) {
NSString *boundObject = [bindingsDict
valueForKey:@NSObservedObject];
NSString *boundKeyPath = [bindingsDict
valueForKey:@NSObservedKeyPath];
[boundObject setValue:newStringValue forKeyPath:boundKeyPath];
}
[self.window endEditingFor:self];
There's a lot more to mimicking the look of iCal / AddressBook editing, though.
Both apps use attributed strings, and the text fields and borderless windows
are sized to fit the attributed string (or the attributed placeholder string,
if no string has been entered). If the string being entered will exceed the
width of the window that popped up, the window will begin to grow to
accommodate the additional letters, and will push text in the main window to
the side to make room once the enter button is pressed.
AddressBook-style editing with the plus and minus buttons to add or remove
fields is also not insignificant.

When ICNTextField receives the controlTextDidEndEditing notification, it
takes the string value from the text field in the borderless window and
displays it properly, but the Core Data attribute to which the original text

I've looked into endEditing and endEditing:, nextKeyView and various forms
of commit, but can't seem to find a way to get the bindings to recognize the

I'd like to do this in a generic fashion, so I can make any text field an

having to write additional code for each text field. Any help would be
appreciated.

They're just text fields. Change the background color, turn off the

I have a typical NSTableView setup where the column content is provided by an NSArrayController. Now say a column is bound to arrayController.arrangedObjects key path a.b.c.d. In this scenario if b changes (even in a KVO-complient way), it will still result in an NSInternalInconsistencyException 'Cannot remove an observer xxx for the key path c.d from old instance of b, most likely because the value for the key c has changed without an appropriate KVO notification being sent.' I understand why this is happening (nothing is observing changes of b, so the actual observer is left dangling). The question is how can I change my design to avoid this situation?

Re: Snapshotting hidden UIViews
You could try making it not opaque (i.e. have isOpaque return NO). Then the view should get drawn, even if it is subsequently over-painted by another view positioned on top of it. That's how it works in Cocoa, at least. Calling setNeedsDisplay on the (common) parent view ought to do it but you will need to return to the run loop before anything actually happens of course.

Re: Best practice example for a setup wizard?
Ian Piper wrote: OK, perhaps I need to rethink how this works. Given that the underlying purpose is to authenticate the user to allow access to an encrypted database, would it make more sense for me to use the user's Mac OS X account credentials? Is there a way (I hesitate to use the phrase best practice again) for my program to authenticate the user that way? It depends on what you mean by the user's account credentials, and how they fit with your database access controls. It seems like Keychain Services may be appropriate. It depends on exactly how your DB access-control works. If it's password-based or encryption-key based, then your app can store and retrieve a specific keychain item (password or key). Initially, if your item doesn't exist in the keychain, your app can prompt the user with a simple dialog. After that, Keychain Services should take over the management and access-enforcement of the item itself. Your app simply tries to read the item from the keychain, and either succeeds (so proceeds with database connection) or fails (so does something appropriate for that failure reason). http://developer.apple.com/Mac/library/documentation/Security/ Conceptual/keychainServConcepts/02concepts/concepts.html There's also this framework, wrapping the basic C functions in Obj-C: http://sourceforge.net/projects/keychain/ There may be other frameworks or libs.

Core Video CIFilters/ playback / compression suggestions?
Hi, We're working with Core Video to play back videos @ 1024 x 768 resolution. The videos are stacked on top of one another and revealed as a user draws over top of them. To achieve this drawing into the stack of videos, we're filtering using CIImage to create alpha masks over top of an individual video. Playback is very choppy, and we haven't been able to determine if it's the compression we're using (i.e. the video assets themselves) or anything to do with the combination of Core Video, Core Image the 1024x768 format. Some problems we're facing is that even if we're only using 2 videos and not doing any filtering, the videos lag. We initially we compressed our original files out, so that the overall file size is much smaller. Even still, with 2 movies @ approx. 50MB each we're having problems. Using TOP, from terminal, to overall system usage we're getting results that the system is chewing up to 180% cpu. We'd be really greatful for any help on whether this is an asset, a code, or a compression issue (or all three).

On Jan 13, 2010, at 16:12, Daniel Wambold wrote: Nevertheless, I agree that the situation seems to suggest that the File Open (load) method that is being invoked by the NSPersistentDocument is creating a new managed object context that is not being attached to the controller. Despite my efforts to force this issue (such as posting the new MOC in a notification object), it fails. I assume this is because I was using the NSPersistentDocument persistent store assignment method, which occurs before the Nib is reconstituted, meaning that the value is lost in the initialization. The next step is to narrow down the problem to a single area. ATM, we don't even know if it's related to nib loading or to Core Data. You may need to simplify your code to find out. I don't know if this is a clue, but I have never been able to get this program to respond to the request for [[NSApp delegate] managedObjectContext]. I DO have a delegate to the Application, but I have not yet done anything with it. Could this be part of the problem? The application delegate has no inherent knowledge of managed object contexts, and anyway -- in the case of a NSPersistentDocument-based application -- the MOC is per-document, not per-application.

Re: IBLibraryObjectTemplate
The IBLibraryObjectTemplate is part of InterfaceBuilderKit, the framework used to create plugins for Interface Builder.

I'm assuming you don't want the IBLibraryObjectTemplate, so to get rid of it, just find the file with the stray IBLibraryObjectTemplate, delete, and you'll be good to go. A quick way to do this is: use the search field in Interface Builder to search for IBLibraryObjectTemplate, and that will show you which objects (if any) are library object templates.

NSArrayController Conceptual Problem
I have a Core Data document based application. In the data model there are five entities. Currently I have a inspector panel with five NSArrayControllers, one for each entity. The panel works well but currently all user interaction is confined to the panel itself. The primary user interface however is a custom view where the model objects are presented to the user all mixed up and in random locations like in a graphics application. The user needs to select one of these objects and then do something with it. Here is the issue. There is a tension between the inspector panel and the primary view. The inspector panel wants one array controller per entity. The primary view wants a single array controller. A single array controller would work great for selection in the primary view. But how would you get one array controller to work for five entities? Multiple array controllers works great for the inspector but the primary view would need query the selected object and then send a message to the proper array controller. I am having a difficult time jumping from the simplified tutorials and sample code to my specific application. So which direction do I head? --Richard ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

It would, of course, be in class mode, not entity mode, and would be bound to a NSArray of the other 5 controllers -- an immutable array property of (likely) your window controller, rather than your data model. Then the primary view would refer to its (single) array controller of interest as 'sixthArrayController.selection', while the inspector would continue referring to the other five array controllers directly. You say nothing that suggests the inspector needs to know which is the selected item in the primary view, but if it needs to know it should be able to do so from 'sixthArrayController.selection', or something derived from it. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Despite how it may look, the order of operations screws you up.
The block gets created first, and only after that happens does the
assignment to b occur. But creating the block copies the value of b.
Because that copy happens before initialization, you get the old,
uninitialized, garbage value of b.
It's easy to fix, though. Just make it so that the block can follow
changes to the value of b that happen after the block is created, by
declaring b with the __block qualifier.

If Array Controller is empty, how to populate pop-up list?
Hi all, I have an Array Controller whose objects are displayed in an NSPopUpButton. I can add and remove objects, and they refresh automatically in the box as expected. However, what can I do if the array controller becomes empty? If I delete all the objects, or if the window starts up with an empty array controller, I'd like for the list to then have a null element that says No objects. Once an object is added, it should go away. But if I choose Insert null placeholder in the pop-up options, the null placeholder is ALWAYS there, which is not good. Is there a way to do this in IB, or is this a thing I should code? And if so, how can I make sure the method is called whenever there is a change to the array controller?

Re: Changing FirstResponder with Inputmethod
I found EXC_BAD_ACCESS error occurs when garbage collection is on only.
But when when garbage collection is off, first letter is not send to
NSTextField if InputMethod is on.
For example, when typing '1' '2' '3' three keys when NSTextField is not first
responder.
If InputMethod is off, NSTextField shows 123.
If InputMethod is on, NSTextField show 23.
Is this bug of OS?
I'm using 10.6.2.

Bindings Problem
I'm sure what I'm trying to do is not that difficult but I've been pulling my
hair out for a while now on this problem.
I have an application whose model could be updated without the user directly
doing anything. So bindings seems like the perfect fit b/c the interface will
reflect these sorts of changes when they occur. But I can't seem to get
updates in my model to appear in the interface. My model is an NSMutableSet
that contains NSMutableDictionaries. I then have a NSTableView with several
columns. I want each column in the table to display a value from each
NSMutableDictionary.
@interface MyController : NSObject
{
NSMutableSet *myset;
}
//I initialize the NSMutableSet in this method.
- (void)awakeFromNib;
//Setter and Getter to ensure KVC compliance.
- (void)setMyset:(NSMutableSet *)set;
- (NSMutableSet *)myset;
//This method is here for testing. A button in the UI is connected to the
method.
//When executed this method creates a new NSMutableDictionary. Adds some
key/value
//pairs to it then adds the NSMutableDictionary to the NSMutableSet (myset).
- (IBAction)addValueToSet:(id)sender;
In Interface Builder I have dragged out an NSObject and set its type to be
MyController. I then dragged out an NSObjectController and set its Content
connection to the MyController object. I then dragged out an NSArrayController
and bound its Content Array binding to the Object Controller with a Controller
Key of selection and a Model Key Path of myset. I also set the
NSArrayController's Class Name to NSMutableDictionary since that is what is
held by my NSMutableSet. I setup a NSTableView in my application's window and
then bound its first table column's Value binding to the NSArrayController
using arrangedObjects as the Controller Key and Caption as the Model Key
Path. Caption is the key to a key/value pair in the NSMutableDictionary that
is held by the NSMutableSet (myset).
In the addValueToSet: method I have the following code:
- (IBAction)addValueToSet:(id)sender
{
NSString *newString = @New Value;
NSMutableDictionary *dict = [[[NSMutableDictionary alloc]
initWithCapacity:1] autorelease];
[dict setValue:newString forKey:@Caption];
[myset addObject:dict];
}
When I click the button in my interface nothing happens. I know the
addValueToSet: method is being called however I would expect the interface to
update based upon my updating the model. Can anybody tell me what I'm doing
wrong?

Re: If Array Controller is empty, how to populate pop-up list?
Uhh, okay so there's another problem I discovered. Below the popupmenu, I have two text fields that are supposed to show two of the attributes of the selected object (in the array controller). But changing the selection in the popupmenu does NOT change the selected item in the array controller. How do I wire the two together such that selecting a different value in the nspopupmenu also changes the selected object in the array controller? Right now the NSPopUpMenu has the bindings set like so: - Content: ArrayController.arrangedObjects - Content Values: ArrayController.arrangedObjects.name Any ideas what else I need to set?? ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Help with Client/Server GameKit
This may net be the right list but hopefully someone has seen this issue and can help me out... I have an IPhone app using GameKit, in client server mode. After I terminate the Client App a few times with the home button, it fails to connect to the server. The problem is, when I send the message, connectToPeer, I receive a timeout error on from the connectionWithPeerFailed, the timeout is set to 30 seconds. Once its in this state one odd thing I notice is that it appears to go into Device Available state at the wrong time, i.e. sometimes even if the server is not running I get a server available state change. If I terminate the server app, and restart the problem does not appear to exist, the client will always connect. If the client is in the bad state, if I restart both apps, they will usually connect. Also in this state if I debug the Client / Server or both.. I can see state change messages in the console for the client, but the server is silent... Its almost like the client can no longer resolve the name of the server device.. Any ideas ?

Unless these are concerns, I wouldn't drop PPC support, since there are still quite a few people out there using PPC Macs that are downloading/buying software for Leopard, even though they're now in the minority. Of course, this will change in the next few years, as new versions of OS X come and go, and PPC becomes a distant memory. After a while, there will still be PPC users, but they probably won't be buying new software, and they probably won't be worth your time. Also, keep in mind that some unfortunate users must run their UB apps under Rosetta on Intel Macs, because they rely on some third-party add-ons that were never ported to X86(-64). This is quite rare, though. That said, if you do decide to drop support, you probably won't receive (m)any complaints. At least I've never received a single complaint from a PPC user about the X86-64-only preference pane I released a few months ago, which required a very specific feature of X86-64-based Macs and couldn't be back-ported.

newbie question -views and MCV model
Hello all, i have a very noob question about the MCV model to display a data file in a view. I'm trying to implement Model-Controller-View. So, so far I created a class called FilterBank that will contain all the data to be plotted plus a method to init from a file. Then I included one instance of the class FilterBank in the myDocument class in the readFromURL: method . When I open a file, myDocument will read and load all the data to the class calling the initFromFile: method of FilterBank, and that works ok. Then I can subclass NSView to hold and plot the image using NSImageRep, etc. My problem is with the controller. I subclassed NSViewController (with the name FilterBankViewController) and tried to bind the class with the file's owner. But I noticed that in IB I cannot do that, actually the bind tab says it's Not Applicable. I don't understand why though, b/c I learned in a tutorial (that loads data from a file and puts that into a table), that you need an NSArrayController to mediate between the table and the file owner. What kind of controller should I use here? How does the view get notified that it should redraw itself and how can I pass the information so that the view knows what to draw?

Thank you for these responses! I think we will roll out with PowerPC but EOL support for it within 6 months of the next major Apple OS release.

In your content binding for the popup button in Interface Builder, check the Inserts Null Placeholder checkbox and enter a value in the Null Placeholder field. -- Rob Keniger ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
