我创建了一个AVCaptureSession并将前置摄像头连接到它上面

do {
   try captureSession.addInput(AVCaptureDeviceInput(device: captureDevice))
   }catch{print("err")}

现在我想开始并停止在touche事件上录制.我该怎么做呢？

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
        print("touch")
        //Start Recording
    }

override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
        print("release");
        //End Recording and Save
    }
