1、拍击UITapGestureRecognizer (任意次数的拍击)
2、向里或向外捏UIPinchGestureRecognizer (用于缩放)
3、摇动或者拖拽UIPanGestureRecognizer
4、擦碰UISwipeGestureRecognizer (一般用以左右切换滑动)
5、旋转UIRotationGestureRecognizer (手指朝相反方向移动)
6、长按UILongPressGestureRecognizer
override func viewDidLoad() { super.viewDidLoad() var v = UIView(frame: CGRect(x: 0, y: 0, width: screenWidth, height: screenHeight)); //点击事件 let handTap = UITapGestureRecognizer(target: self, action: #selector(funTap)) v.addGestureRecognizer(handTap) //拖动事件, 任意方向 let handDrag = UIPanGestureRecognizer(target: self, action: #selector(funDrag)) //v.addGestureRecognizer(handDrag) //左右滑动,不可与拖动事件UIPanGestureRecognizer并存 , 默认只支持向右 let handLeftRight = UISwipeGestureRecognizer(target: self, action: #selector(funLeftRight)) handLeftRight.direction = .left //支持向左 v.addGestureRecognizer(handLeftRight) self.view.addSubview(v) } func funTap(sender: UIPanGestureRecognizer){ print("funTap_"+String(arc4random())); } func funDrag(sender: UIPanGestureRecognizer){ var Point = sender.translation(in: self.view);//现对于起始点的移动位置 Point = sender.location(in: self.view);//在整个self.view 中的位置 print("funDrag_"+String(describing: Point.x)+","+String(describing:Point.y)) if(sender.state == .began){ print("begin: "+String(describing: Point.x)+","+String(describing:Point.y)) }else if(sender.state == .ended){ print("ended: "+String(describing: Point.x)+","+String(describing:Point.y)) }else{ print("ing: "+String(describing: Point.x)+","+String(describing:Point.y)) } } func funLeftRight(sender: UIPanGestureRecognizer){ print("funLeftRight_"+String(arc4random())); }
如果想获取 参数 sender:UIxxxGestureRecognizer 中的视图 信息
func showLongPress(sender:UILongPressGestureRecognizer){ print((sender.view as! XXX).url.text); }
** 传递 和 获取 UIButton 信息
func xxx(sender: UILongPressGestureRecognizer){ let btn:UIButton = sender.view as! UIButton print(btn.tag) }
