I have an application and I need it to send and receive data over wifi. Can anyone point me into the right direction? I don't know where to start or what frameworks I must use... Some say that I should use Bonjour, but I don't even know how to operate Apple's sample code like WiTap for that. Isn't Apple's WiTap example supposed to find my computer via WiFi? Well, I have my computer wirelessly connected to an Airport express base station, but WiTap doesn't recognize it... Same thing happens when using BonjourWeb. No results show up on the screen of my iPhone. Can anyone point me into the right direction or at least tell me if Apple's sample code worked for him?
