I'm seriously stuck. I've been developing an app for my boss for the last few months in cocos-2dx. For this project I need to be able to select and play any music from the users IOS library. I've got it to work using MPMediaPickerController which gives me access to all the music's data, but I need to play it in the C++ file with SimpleAudioEngine to make it work with the rest of my code. Any way to make this work?
