Kyle et al,
No problem -- here's my code. There is obviously something i'm not
getting, so any help is truly appreciated.
First, my view controller has a showAnimation method that is called to
play the currently loaded animation:
- (void)showAnimation
{
// only play the animation if the preloader thread has finished ...
lilappAppDelegate *delegate = (lilappAppDelegate *)
[[UIApplication sharedApplication] delegate];
[delegate stopAnimations];
if(YES == delegate.animationPreloaded)
{
delegate.animationView.animationImages =
delegate.animationArray;
[delegate playAnimation:self.view];
[delegate preloadNextAnimation];
}
}
... and I run a thread to preload the next animation (this code always
preloads the same one, but the idea is that they'll change, and I
don't want to load them all at once and waste memory):
- (void)preloadAnimationThread
{
NSAutoreleasePool *outerPool = [[NSAutoreleasePool alloc] init];
self.animationPreloaded = NO;
int frameIndex = 0;
[NSThread sleepForTimeInterval:5];
[self performSelectorOnMainThread:@selector(releaseAnimations)
withObject:nil waitUntilDone:YES];
[self.animationArray release];
self.animationArray = [[NSMutableArray alloc] init];
for (frameIndex = 0; frameIndex < 47; frameIndex += 2)
{
NSString *frameName = [NSString stringWithFormat:@"clapping_
%05i.png", frameIndex];
// I tried [UIImage imageContentsFromFile], but it resulted in
animations that played on the sim but
// not on the device ...
[self.animationArray addObject:[UIImage imageNamed:frameName]];
}
self.animationPreloaded = YES;
[outerPool release];
}
- (void)releaseAnimations
{
self.animationView.animationImages = nil;
}
- (void)stopAnimations
{
[self.animationView stopAnimating];
}

My question -- what is the correct way to release the UIImageView's
animatedImages array? I assign an NSMutableArray to it, play the
animation, then set the UIImageView's animatedImages to nil. I
then release the NSMutableArray and recreate it. Is this correct?
Your question is meaningless without context, and the fact that
you're asking it indicates a lack of familiarity with the Cocoa
memory management rules.
Since we have been asked not to paraphrase them here, all I can
suggest is that you review the documentation and, if you're still
confused, post your code.
