I've built the WiTap example both for my iPhone and for the simulator. Bonjour finds properly the other part on both, nevertheless (a) if I click the iPhone name on the simulator, all works well (the "game" does start) (b) if, though, I tap the Mac name on the iPhone, it goes blue--and nothing happens (in the code, the stream delegate ...

Hi Everyone: I have found a lot of information on using UIImagePickerController to let the user choose the image they want from the Photos application's data. I am wondering how I can create this same effect on 3.0, as it doesn't seem as if a lot of the old code works anymore. In addition, I would like the user to be able to take a ne...
