title: Drawing a path with CAKeyFrameAnimation on iPhone
body: <p>I want to draw a path gradually, i.e. I want the path to appear as if it is drawn by hand. I have managed to create the path I need. I have also managed to create a CAKeyFrameAnimation that uses this path. But so far I can only move an object along this path. I would like to both move an object (say a pencil) along the path, and have the path appear as if it is drawn.</p>
  
  <p>Any pointers? </p>
