Is MPNowPlayingInfoCenter compatible with AVAudioPlayer?

Question

I start -play with AVAudioPlayer, and then set the nowPlaying dictionary like this:

NSMutableDictionary *songInfo = [[NSMutableDictionary alloc] init];
        
MPMediaItemArtwork *albumArt = [[MPMediaItemArtwork alloc] initWithImage: [UIImage imagedNamed:@"AlbumArt"]];
[songInfo setObject:@"Audio Title" forKey:MPMediaItemPropertyTitle];
[songInfo setObject:@"Audio Author" forKey:MPMediaItemPropertyArtist];
[songInfo setObject:@"Audio Album" forKey:MPMediaItemPropertyAlbumTitle];
[songInfo setObject:albumArt forKey:MPMediaItemPropertyArtwork];
[[MPNowPlayingInfoCenter defaultCenter] setNowPlayingInfo:songInfo];

The lock screen always shows a pause button. I receive the remote control events correctly and I can toggle play/pause through the remote control events, but the lock screen keeps showing "pause" even when it is playing.

Now I seen this work with MPMoviePlayerController. Can someone explain how does the MPNowPlayingInfoCenter determine if it should show a play or a pause button?

Answer 1

Have you set the correct AVAudioSessionCategory on the AudioSession? it needs to be AVAudioSessionCategoryPlayback I believe to get it to work.
