Line Drawing Game Help Tutorial for iPhone

I am looking for anyone that can help create some sourc开发者_StackOverflow社区e and a tutorial with me to answer how to create a game like "air control" or "harbor patrol" - just a simple source file where a user can draw using their finger and an object will follow - no need for final collision detection just the simple follow path source.

Thanks Matthew

PS If anyone knows of a tutorial already out there please point it out I do not want to reinvent the wheel, I would like to screen capture the tutorial and post it for others when finished. Anyone who helps will get attribution and a link to their sites.
