These two lines are interesting:
Code:
self.myImageView.animationImages=myMutableArray;
[myMutableArray removeAllObjects];
I assume animationImages is a property with a "copy" attribute? Otherwise, why would you be setting it and then immediately emptying the array?
If it's a retain, then your imageView now has an empty array in "animationImages", which is most likely not what you wanted.
Also, where exactly is the program crashing? What exception are you getting?
