I am looking for a more convenient way of drawing a path than by drawing it programmatically. Is there any way of drawing a path in Photoshop (or Illustrator) and getting that path to the iPhone to use in a CAKeyframeAnimation? e.g. by exporting the point data, or by importing the .ai file?
I ended up using Opacity. Opacity is a nifty little program that will allow you to draw paths (or import images) and export source code for iOS (e.g. Quartz).
