Audio playing in background not working in iOS Simulator

问题

I've seen lots of questions about playing audio in the background. These questions often ask why the audio plays in the background of the simulator, yet the device simply wouldn't.

In my case, it's reversed.

When I tested my sample app in my iPad, it worked perfectly. However, when I began testing in the simulator, it simply wouldn't continue playing in the background.

Here are the codes I used:

NSURL *url = [NSURL URLWithString:firstSong];

audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
[audioPlayer setNumberOfLoops:-1];
[audioPlayer setCurrentTime:0];

[[AVAudioSession sharedInstance]setCategory:AVAudioSessionCategoryPlayback error:nil];
[[AVAudioSession sharedInstance]setDelegate:self];
[[AVAudioSession sharedInstance] setActive:YES error:nil];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
[self becomeFirstResponder];

[audioPlayer play];

Can anyone tell me why this won't work? Is it a bug or something?
