IOS 流式传输视频时检测通话中断

Question

我正在使用 AVPlayer 流式传输视频，我想在 GSM 呼叫到来时暂停视频，并在呼叫结束且控制权返回我的应用程序时恢复。我怎样才能做到这一点？

Answer 1

我想出来了，我用 AVAudioSessionInterruptionNotification 做到了。下面是代码片段

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(routeInterrypt:) name:AVAudioSessionInterruptionNotification object:nil];


-(void)routeInterrypt:(NSNotification *)notification {
    NSDictionary *dic = notification.userInfo;
    int changeReason= [dic[AVAudioSessionRouteChangeReasonKey] intValue];
    if (changeReason == AVAudioSessionRouteChangeReasonUnknown) {
        if (_state == TYVideoPlayerStateContentPlaying || _state == TYVideoPlayerStateBuffering) {
            [self pauseContent];
            return;
        }
    } }
