Since the forKey value is NSString, where can I find a complete list of all possible values in the Apple documentation? Thanks
List of CALayer animation properties:
http://developer.apple.com/library/ios/#DOCUMENTATION/Cocoa/Conceptual/CoreAnimation_guide/Articles/AnimProps.html#//apple_ref/doc/uid/TP40005942-SW1
and / or here

The method addAnimation:forKey:does not do what you think.
addAnimation:forKey:
. - animationForKey:.
animationForKey:
, /, keyPath CABasicAnimation.
keyPath
CABasicAnimation
