推荐答案

因此不知道检测QuickTime播放器的录音。

Thus don't know detect QuickTime Player recording.

但是我找到了一个解决方法。

But I Found a solution with some trick.

如果正在运行QuickTime Player录制，AVAudioSession的输出portType已更改为HDMI输出。

If QuickTime Player recording is running, AVAudioSession's output portType has been changed to HDMIOutput.

所以我编码如下......（Swift 2.2）

So I coding as follows...(Swift 2.2)

func checkOutputPortType() {
    let asRoute = AVAudioSession.sharedInstance().currentRoute
    for output in asRoute.outputs {
        if output.portType == AVAudioSessionPortHDMI {
            // something you want..
        }
    }
}

在ViewDidLoad中插入该函数并添加 AVAudioSessionRouteChangeNotification 通知。

Insert that function in ViewDidLoad and added AVAudioSessionRouteChangeNotification notification.

NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(checkOutputPortType), name: AVAudioSessionRouteChangeNotification, object: nil)

谢谢。
