My issue is the HUD that accompanies a change in the MPMusicPlayerController's volume property. Whilst there is a solution, I want to know if it is acceptable by Apple to hide the MPVolumeView to prevent the HUD from showing?
And on another note, if I choose not to use the MPVolumeView class, will the user still have the option to play audio from the app on an AirPlay device via the multi-tasking bar?
