How to unset delegate on UIView setAnimationDelegate: call?
- by morticae
I am receiving crash reports that appear to be from a UIView animation calling a delegate that has been dealloced.

2 UIKit 0x31c565d2 -[UIViewAnimationState animationDidStop:finished:]
3 QuartzCore 0x30045a26 run_animation_callbacks
I am setting the current view controller as the delegate for animations using the following pattern:
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:0.5];
[UIView setAnimationDelegate:self];
...
[UIView commitAnimations];
My question is, how do I set that delegate reference to nil in my dealloc method? Is there some way to retain a reference to an animation? Or fetch animations in progress?
