For example code that performs an animation along a curved path, you can consult my answer to this question. As Till suggests, you'll want to use a CAKeyframeAnimation with a Core Graphics curved path set to the animation's path property.

I created a tutorial that includes a working example of animating a view object (a UImageView) along a curved path, and posted it on GitHub. You can find it here:
