UIPanGestureRecognizer影响UISlider

在处理视频播放过程中，添加了UIPanGestureRecognizer手势用于处理音量和屏幕亮度的调节，在滑动UISlider时候一直响应UIPanGestureRecognizer的手势事件，导致UISlider失效，处理方式是使用手势代理UIGestureRecognizerDelegate中的方法optional public func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool

处理代码如下：

        let panGesture = UIPanGestureRecognizer(target: self, action: #selector(panGestureAction(_:)))
        panGesture.maximumNumberOfTouches = 1
        panGesture.delegate = self
        self.addGestureRecognizer(panGesture)

实现代理方法

func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
        //屏蔽掉滑动条
        if touch.view == self.processSlider {
            return false
        }
        return true
    }
