Edit Question
Title
Body
I'd like to have a better understanding of this parameter in + (id)animationWithKeyPath:(NSString *)keyPath They just say: "The key path of the property to be animated." In some example snippets I see things like: CABasicAnimation *fadeInAnimation = [CABasicAnimation animationWithKeyPath:@"opacity"]; CAKeyframeAnimation *animatedIconAnimation = [CAKeyframeAnimation animationWithKeyPath: @"frameOrigin"]; Is there a list or rule of thumb for determining the correct key path parameter? i.e. when I want to animate the width of a frame, what kind of rules would I have to follow to get to the correct key path parameter string?
