 ** tapges 与 uibutton 冲突, 如果是button 就不执行 tapges 

    func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
        if((touch.view)?.isKind(of: UIButton.self))!{
            return false
        }
        return true;
    }

 

 

 

** 两个滑动 手势 冲突，

class ViewController: UIGestureRecognizerDelegate{
	
	//下面两个事件在 .began 前触发 , 在触发时就设置X起始坐标
    func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
        let point = gestureRecognizer.location(in: self.view);
        if(point.x < xxx || point.x > (selfWh-xxx)){
            selfDrag_start_x = point.x;
            return true;
        }
        return false
    }
    func a(){
        let ges = UIPanGestureRecognizer(target: self, action: #selector(webBoxDrag))
        ges.delegate = self
        xx(uiScrollView).addGestureRecognizer(ges)
    }

}

 

 

 

 扩展

        if(gestureRecognizer.isKind(of: UIPanGestureRecognizer.self) == false){

            return false;

 

        }

如果不是 UIPanGestureRecognizer 就直接返回false
