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
}
