Question

I am showing media hierarchy in the table view. When I tap on a song in the table view, it plays the song using MPMoviePlayerViewController. But when I click on the done button, the sound stops playing . I have created the following code:

        NSURL *songUrl=[operationControl getSong:stringId];
    mediaPlayerController = [[MPMoviePlayerViewController alloc] initWithContentURL:songUrl];
    [self presentModalViewController:mediaPlayerController animated:YES];
    [[mediaPlayerController moviePlayer] play];

I to want to browse the media hierarchy as well as play the song in the background. How can I achieve this?

You should start AVAudioSession and declare in main plist that your application plays music in background.

in didFinishLaunchingWithOptions:

  // Setup audio session
  AVAudioSession *sharedSession = [AVAudioSession sharedInstance];
  [sharedSession setCategory:AVAudioSessionCategoryPlayback error:nil];

in applicationDidBecomeActive:

  [sharedSession setActive:YES error:nil]; // FIXME: Error handling

In main plist add: Required background modes – App plays audio
