我有MPMoviePlayerController应该在后台播放视频的音频,应该由多任务播放/暂停控件控制.

更新.plist文件Required background modes并调用以下内容后:

- (void)startBackgroundStreaming
{
    [[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
    [self becomeFirstResponder];

    NSError *activationError = nil;
    AVAudioSession *audioSession = [AVAudioSession sharedInstance];
    [audioSession setCategory:AVAudioSessionCategoryPlayback error:&activationError];
    [audioSession setActive:YES error:&activationError];

}

应用程序图标出现在多任务播放/暂停栏中,但这些按钮不响应.

谢谢!
