AVPlayer 在后台流式传输音频

我在后台模式下播放 AVPlayer 时遇到问题，就像这里和网络上其他地方的很多人一样。我已经完成了我认为应该有效的操作，但仍然不起作用...我认为我的问题可能是我设置和使用 AudioSession 和 AVPlayer 的位置。

1）“音频”键位于我的 Info.plist 的 UIBackgroundModes 中

2）在 AppDelegate 中像这样设置 AudioSession （在 didFinishLaunchingWithOptions 中初始化）：

AVAudioSession *audio = [[AVAudioSession alloc]init];
[audio setCategory:AVAudioSessionCategoryPlayback error:nil];
[audio setActive:YES error:nil];

3）我使用也在 AppDelegate 中实现的 AVPlayer （不是 AVAudioPlayer）。（在 AudioSession 之后的 didFinishLaunchingWithOptions 中初始化），就在 AudioSession 之后，

// Load the array with the sample file
NSString *urlAddress = @"http://mystreamadress.mp3";

//Create a URL object.
self.urlStream = [NSURL URLWithString:urlAddress];  
self.player = [AVPlayer playerWithURL:urlStream];
//Starts playback
[player play];

每次应用程序进入后台时（当我按“主页”按钮时），音频都会暂停。

I have a problem with the AVPlayer playing in background mode, like a lot of people here and everywhere on the web. I've done what I think is supposed to work, but is still doesn't... I think my problem might be where I set and use my AudioSession and AVPlayer.

1) The "audio" key is in UIBackgroundModes of my Info.plist

2) AudioSession set like this in AppDelegate (initialised in didFinishLaunchingWithOptions):

AVAudioSession *audio = [[AVAudioSession alloc]init];
[audio setCategory:AVAudioSessionCategoryPlayback error:nil];
[audio setActive:YES error:nil];

3) I use an AVPlayer (not AVAudioPlayer) also implemented in AppDelegate. (initialised in didFinishLaunchingWithOptions, after the AudioSession), right after the AudioSession

// Load the array with the sample file
NSString *urlAddress = @"http://mystreamadress.mp3";

//Create a URL object.
self.urlStream = [NSURL URLWithString:urlAddress];  
self.player = [AVPlayer playerWithURL:urlStream];
//Starts playback
[player play];

And still, the audio is suspended everytime the app goes in background (when I press the "Home" button).
