How to replace the custom animation for a CALayer appearing?

I know this is 3 months old but I was looking for an answer for a similar problem and notice that this doesn't have an answer (an I'd like some rep ;) I'm overwriting the actionForLayer:forKey: on a UIView (iPhone SDK) that is automatically set as the delegate to it's backing CALayer in order to inject a different action for anchorPoint. I notice I can get access to the old value via the presentationLayer of the CALayer and the new value is in the modelLayer. But what I think is happening in your case is that the system is calling for the onOrderIn action (perhaps at the time that the layer is added to the view hierarchy) before you have told the layer it's bounds.In fact this is normal You should be waiting for the "bounds" in addition to the "onOrderIn" key Are you waiting for other keys?

"onOrderOut" or "hidden"? Cheers, Corin.

Gosh, yeah, this was a while ago. Don't want to mark this as the answer until I test it with whatever I was trying to do back then. I'll have to get back to you on it.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
