Moving image along predetermined path?

Question

Is it possible to set an image into motion along a predetermined path with the push of a button in iphone SDK? I'm not looking for anything fancy. I working on a simple concept, but this would save a lot of animation work.

Answer 1

Yes. You can animate any CALayer along a path by creating a CAKeyframeAnimation and assigning a CGPath to its path property. See this blog post by Bill Dudney for an example.
