隐藏音量级别弹出 MPMusicPlayerController Xcode

我正在使用 MPMusicPlayerController 在我的应用程序中播放 mp3 列表。

唯一的问题是，当我根据应用程序配置设置音量级别时，会弹出“音量级别”。

我试图找到任何财产来隐藏它，但我没有找到。

我使用的代码是：

if (audioPlayer)
    if ([audioPlayer isPlaying])
        [audioPlayer stop];

self.musicPlayer = [MPMusicPlayerController applicationMusicPlayer];

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handlePlaybackStateChanged:) name:MPMusicPlayerControllerPlaybackStateDidChangeNotification object:self.musicPlayer];

[self.musicPlayer beginGeneratingPlaybackNotifications];

[self.musicPlayer setAccessibilityElementsHidden:YES];
self.musicPlayer.volume = volume;

[self.musicPlayer setQueueWithItemCollection:mediaItemCollection];

self.musicPlayer.repeatMode = MPMusicRepeatModeAll;

[self.musicPlayer play];

我的问题是，有什么方法可以避免这种弹出窗口吗？

谢谢。

I'm using MPMusicPlayerController to play a list of mp3 in my app.

The only problem is when I set the volume level, according with app configuration, appears a Volume Level pop up.

I tried to find any property in order to hide it, but I didn't find.

The code I'm using is:

if (audioPlayer)
    if ([audioPlayer isPlaying])
        [audioPlayer stop];

self.musicPlayer = [MPMusicPlayerController applicationMusicPlayer];

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handlePlaybackStateChanged:) name:MPMusicPlayerControllerPlaybackStateDidChangeNotification object:self.musicPlayer];

[self.musicPlayer beginGeneratingPlaybackNotifications];

[self.musicPlayer setAccessibilityElementsHidden:YES];
self.musicPlayer.volume = volume;

[self.musicPlayer setQueueWithItemCollection:mediaItemCollection];

self.musicPlayer.repeatMode = MPMusicRepeatModeAll;

[self.musicPlayer play];

My question is, Any way to avoid this pop up?

Thanks.
