306959 iphone game framework

Hello, I'm looking to receive a skeleton for an iPhone game so I can learn objective-c, cocoa and produce a game at the same time. I would like to see plenty of comments. Im experienced in various languages, primarily C/C++. The game follows a guitar hero/tap tap revolution theme. So, audio is an important component. Also, in terms of input, pattern detection is required (eg. swipes, taps, etc). Other than these two components, the game is quite simple as a whole.
