This application can pair a PS3 Sixaxis controller to your iOS device using your Mac.
This project uses MobileDevice.framework to grab the bluetooth address of a connected iOS device, and program it into a connected Sixaxis controller using IOKit.framework.
The project in its current state is a raw code dump from a while ago, and is in severe need of refactoring/updating.
It is being released in time for an update of Matthias Ringwald's Blutrol, which allows you to use your PS3 controller to play games on your iOS device.
