我在网上做了很多研究，我认为这应该是在后台播放音频的正确方法。但是，它就是行不通。我不知道哪里出了问题。请帮忙。谢谢。
最佳答案
[[AVAudioSession sharedInstance] setActive:NO error:nil];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback withOptions:AVAudioSessionCategoryOptionMixWithOthers error:nil];
[[AVAudioSession sharedInstance] setActive: YES error: nil];
如果你想在应用程序处于后台时播放音频，你应该使用类别 Playback 而不是 playAndRecord。 另外需要勾选project->target->Capabilities->backgroundMode中的Audio和airPlay
