MPNowPlayingInfoCenter nowPlayingInfo ignored for AVPlayer audio via AirPlay

Question

I have implemented audio playback using AVPlayer, playing a remote mp3 url.

I want to display the information about the currently playing audio using the MPNowPlay

Answer 1

Ok - I dug through the apple dev forums and found a hint.

If you are using AVPlayer for audio only, and want it to work in the background while doing airplay, you need to disable the allowsAirPlayVideo setting.

Apparently AVPlayer on iOS 5+ assumes that it is playing back video via AirPlay, and so does not allow backgrounding, unless you explicitly disable video AirPlay.

Once you disable this (i.e. self.player.allowsAirPlayVideo = NO;) then your audio will still play via AirPlay, but now it will now show the audio/ipod like interface correctly.

Answer 2

If you're on iOS7 you've got to disable external playback :

self.player.allowsExternalPlayback = NO;
