I think this is what you're looking for: http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/CoreAn imation_guide/Articles/KVCAdditions.html What this extremely cool first section is trying to tell you is that you can set an arbitrary non-existent key on your animation and retrieve it later. "Arbitrary" means you define the key - as if a CAAnimation were an NSDictionary. So you can mark your animation in any way you want, as a way of identifying it later. Example code typed in mail, don't take literally: CATransition *animation = [CATransition animation]; [animation setValue: @"fadeIn" forKey: @"wtfIsThis"]; And later: - (void)animationDidStop:(CAAnimation *)theAnimation finished: (BOOL)flag { id wtf = [theAnimation valueForKey: @"wtfIsThis"]; // and so on m. -- matt neuburg, phd = m...@tidbits.com, <http://www.tidbits.com/matt/> A fool + a tool + an autorelease pool = cool!
