You want to look at CGPathApply (this is the short answer to your more refined question). You supply it with a function and it will call that function for each element (these will be lines and arc and closes) of the path.

Then you can figure out which direction each item is drawn in (I think this could actually be the hardest part) and rather then using strokeStart/strokeEnd one each subpath draw it in a layer with a mask and move the mask across the layer.
