Iphone : animating a CALayer sublayer?

Don't add CAAnimation s during the drawRect: method. CoreAnimation calls it when it needs to redraw the content of the view (which could be at any time). You should instead add the animation after the view has been added to its parent.

You can't animate the frame property. Animate the bounds or position instead.

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.
