AVFoundation AudioPlayer

I'm trying to use the AudioPlayer class that's included in Apple's AVFoundation framework. The problem is xcode for some reason won't properly import the AVFoundation framework. I can't use the #import <AVFoundation/AVFoundation.h> to include the namespace, it won't work, and I don't know why. It shows up in the explorer on the left side, and I c开发者_开发技巧an use other namespaces and classes. If anyone can help, I'd be appreciative. Thanks.
