Re: Does [NSApp setApplicationIconImage] leak memory?

Hi all,

Before I file a bug report against this, I just thought I'd check I'm
not being monumentally stupid first!

I'm trying to animate my app's Dock icon, which works fine and looks
great, but unfortunately, it appears to leak memory like crazy.
Every time I call [NSApp setApplicationIconImage:(NSImage *)] and
pass it pointer to an existing image, it leaks more memory.


 Wrap each call to setApplicationIconImage in an autorelease pool creation
 and release, like this:

        NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
        [NSApp setApplicationIconImage: whatever];
        [pool release];

 I think you'll find that solves the problem.

Ok, stupid question time.

1. Is the need for the autorelease pool because of the use of
setApplicationIconImage, or because of the array that is being used in
conjunction with setApplicationIconImage?

2. Would putting the calls to setApplicationIconImage in a class
method also stop the memory leak?

Thanks,

Certainly not a stupid question, in fact, now *I* feel stupid for not trying that first suggestion earlier. Your idea of removing the array from the equation also solves the leak and I suspect is more efficient than creating and releasing a tonne of autorelease pools.

Thanks guys.
