MPNowPlayingInfoCenter nowPlayingInfo ignored for AVPlayer audio via AirPlay
问题 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 MPNowPlayingInfoCenter nowPlayingInfo method. When I lock the screen, I do see the image and title I set, so I know that this method is registering the information in some way, but when I switch to AirPlay to an AppleTV, the display looks like a generic video output, with the progress bar at bottom, but elapsed time and duration correctly
