I\'m currently attempting to set up background audio for an app I\'m developing for iOS 4. The app doesn\'t have a dedicated music player viewController, howeve
viewController
No need to subclass Window or forward events. Simply handle it from your main view controller. See the Audio Mixer (MixerHost) example for details.
