setAnimationDidStopSelector: not getting called - objective-c

Question

I know this question gets asked a lot but i have tried all the other answers and i can't figure out why the animation stop selector does not get called. Here is the code:
-(void) moveImage:(UIImageView *)image duration:(NSTimeInterval)duration curve:(int)curve x:(CGFloat)x y:(CGFloat)y annKey:(NSString *) annKey{
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:duration];
[UIView setAnimationCurve:curve];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDidStopSelector:#selector(animationFinished:finished:context:)];
CGAffineTransform transform = CGAffineTransformMakeTranslation(x, y);
image.transform = transform;
[UIView beginAnimations:annKey context:NULL];
[UIView commitAnimations];
}
This is the main animation function that gets sent all the correct parameters.
- (void)animationFinished:(NSString *)animationID finished:(BOOL)finished context:(void *)context
{
if ([animationID isEqualToString:#"Burn"])
{
NSLog(#"Animation: %# has finished.",animationID);
}
NSLog(#"This does not get called, why not?");
}
None of my NSLogs display text. What am i doing wrong?

Answer 1

You need tho do -
[UIView beginAnimations:annKey context:NULL];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(animationFinished:finished:context:)];
// Now define rest.
[UIView setAnimationDuration:duration];
[UIView setAnimationCurve:curve];
[UIView setAnimationBeginsFromCurrentState:YES];
CGAffineTransform transform = CGAffineTransformMakeTranslation(x, y);
image.transform = transform;
[UIView commitAnimations];

Not sure what the problem is, but you really shouldn't be using beginAnimations/commitAnimations. Instead, use block animations. You define the completion code directly in the completion portion of the call.
[UIView animateWithDuration:2.0
delay:0.0
options:UIViewAnimationOptionCurveEaseOut
animations:^{
// animation code
}
completion:^(BOOL finished){
// completion code
}];
