Making an iPhone game using only Interface Builder

Can you make an iPhone game using only the interface builder and no additional libraries? Yes, and I’ll show you how.
If you are going to build a game for iPhone, I highly recommend using a game library like cocos2d. But before you dig in and learn and entirely new framework, you can tear through most of the basics — acceleration, sounds and music, touch control — by building a simple game using only IB and some png files.

This is exactly how I built my first iPhone game, Clownce. I am making the source to that game public so people can look it over. If you find it helpful, please support this effort by spending a whopping $.99 on Clownce in the app store:
