xcode - MPNowPlayingInfoCenter info is not displayed on iOS 8
Solution 1:
The problem is that you are not satisfying the requirements to become master of the lock screen and control center, as I explain in my book. You should be seeing the modern (iOS 8) equivalent of this:
The fact that you are not seeing it suggests that you are omitting one or more of the requirements, which I list (quoting directly from my book here):
- Your app must contain a UIResponder in its responder chain that
returns YES from
canBecomeFirstResponder, and that responder must actually be first responder. - Some UIResponder in the responder chain,
at or above the first responder, must implement
remoteControlReceivedWithEvent:. - Your app must call the UIApplication
instance method
beginReceivingRemoteControlEvents. - Your app’s audio session’s policy must be Playback.
- Your app must be emitting some sound.
I don't know which of those you are omitting; it could be more than one. You might like to compare your code with a working example, here:

Solution 2:
Want to expand @matt's answer - setting nowPlayingInfo is useless when you use AVAudioSessionCategoryOptionMixWithOthers option.
