首先请注意，useApplicationAudioSession现在已被弃用(iOS 6)

设置环境音频会话将防止在其他应用程序中停止audo

Setting the ambient audio session will prevent stopping audo in other apps

在您的代码中的某处设置:[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:nil];

Set this somewhere in your code:[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:nil];
