1.cocos是个坑

2.修改 cocos/audio/apple/AudioEngine-inl.mm

：

{ if ([[[UIDevice currentDevice] systemVersion] intValue] > 5) { [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleInterruption:) name:AVAudioSessionInterruptionNotification object:[AVAudioSession sharedInstance]]; - [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleInterruption:) name:UIApplicationDidBecomeActiveNotification object:[AVAudioSession sharedInstance]]; + [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleInterruption:) name:UIApplicationDidBecomeActiveNotification object:nil]; } else { AudioSessionInitialize(NULL, NULL, AudioEngineInterruptionListenerCallback, self);
