AUIOClient_StartIO在后台播放歌曲时失败

Question

我使用 Spotify iOS SDK 作为流媒体服务来播放音乐。因为我必须处理应用程序的中断，所以我已经集成了 AVAudioSession 。

请找到以下代码。

AVAudioSession *session = [AVAudioSession sharedInstance];
NSError *audioSessionError = nil;
[session setCategory: AVAudioSessionCategoryPlayAndRecord
               error: &audioSessionError];

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(audioSessionInterruptionNotification:)
                                             name:AVAudioSessionInterruptionNotification
                                           object:session];

-(void)audioSessionInterruptionNotification:(NSNotification*)notification {

//Check the type of notification, especially if you are sending multiple AVAudioSession events here
NSLog(@"Interruption notification name %@", notification.name);

if ([notification.name isEqualToString:AVAudioSessionInterruptionNotification]) {
    seccReason = @"Interruption notification received";

    //Check to see if it was a Begin interruption
    if ([[notification.userInfo valueForKey:AVAudioSessionInterruptionTypeKey] isEqualToNumber:[NSNumber numberWithInt:AVAudioSessionInterruptionTypeBegan]]) {
        NSLog(@"Interruption began");

    } else if([[notification.userInfo valueForKey:AVAudioSessionInterruptionTypeKey] isEqualToNumber:[NSNumber numberWithInt:AVAudioSessionInterruptionTypeEnded]]){
        NSLog(@"Interruption ended!");
        //Resume your audio
    }
  }
}

在后台测试应用程序时，我遇到了“ AUIOClient_StartIO失败”的问题，所以我在google上搜索过，发现它可能与 AVAudioSession 类别，所以我将其从 AVAudioSessionCategoryAmbient 更改为 AVAudioSessionCategoryPlayAndRecord ，但我仍然遇到了问题。

请指导我应该做些什么改变才能完成它。
