iPhone Native Pong Application: the real "sweet" SDK
The native iPhone hack I put together for the C4[1] conference is in the process of a "wow, I hope somebody can read this code someday" cleanup. I will release the source in the coming days. Stay tuned for a download link.
In the meantime, here are a couple of teasers.
Screenshots:
And here is some code for playing a sound file from your native iPhone Application's bundle (with the class-dump'd headers you'll need, too). The iPhone, as was mentioned by everyone with a native hack at C4, has some really intelligent API. Hats off, ladies and gentlemen, to the iPhone team. They must be having a grand ol' time internally playing with this thing.
