Hi I'm creating coloring book and I need help with drawings.
Look at following url

There is flash example of what I need. You can draw different color lines and what is most important, each part of the picture is colored separately - it means that of you are coloring one circle, other circles stay clear. Also if you are coloring the background circles are clear - I hope you understand what I mean (just color the picture from flash example with different colors and you will know how it should work)
The code should be created in native xcode frameworks (like cocoa, no cocos2d or so)
I would need the source code so I can use it in my application.
