Swift 多种手势

• 一，轻拍

//轻拍
        let tap = UITapGestureRecognizer()
        self.view.addGestureRecognizer(tap)
        tap.addTarget(self, action: #selector(tapAction))
        //拍几下，
        tap.numberOfTapsRequired = 2
        //几个手指拍
        tap.numberOfTouchesRequired = 2

• 二，长按

//长按
        let long = UILongPressGestureRecognizer()
        self.view.addGestureRecognizer(long)
        long.addTarget(self, action: #selector(longAction))
        //长安的时间  默认是0.5
        long.minimumPressDuration = 1
        //长按时可以挪动的最小距离  默认是10
        long.allowableMovement = 15
        //长按的手指数，次数同轻拍

• 三，轻扫

//轻扫
        let swip = UISwipeGestureRecognizer()
        swip.direction = .left
        swip.addTarget(self, action: #selector(swipAction(swip:)))
        self.view.addGestureRecognizer(swip)
        let swip1 =    UISwipeGestureRecognizer()
        swip1.direction = .right
        swip1.addTarget(self, action: #selector(swipAction(swip:)))
        self.view.addGestureRecognizer(swip1)

• 四，旋转

//旋转
        let rota = UIRotationGestureRecognizer()
        self.view.addGestureRecognizer(rota)
        rota.addTarget(self, action: #selector(rotaAction))
        //旋转的角度  rota.rotation

• 五，捏合，拖动

//捏合
        let pin = UIPinchGestureRecognizer()
        pin.addTarget(self, action: #selector(pinAction))
        self.view.addGestureRecognizer(pin)
        //缩放比
        //pin.scale
        
        //拖动
        let pan = UIPanGestureRecognizer()
        pan.addTarget(self, action: #selector(panAction(pan:)))
        self.view.addGestureRecognizer(pan)

• 各种手势的方法

//拖动的方法
    func panAction (pan:UIPanGestureRecognizer) {
        //返回当前拖动的位置在self.view上的位置
//        print(pan.translation(in: self.view))
        print(pan.translation(in: self.view))
        
    }
    //捏合的方法
    func pinAction() {
        print("捏合")
    }
    //旋转的方法
    func rotaAction() {
        print("旋转")
    }
    //轻扫的方法
    func swipAction(swip:UISwipeGestureRecognizer) {
        //获取轻扫的方向
        let dir = swip.direction
        if dir == .left {
            
        }else if dir == .right {
            
        }
        
}
    //长按得方法
    func longAction() {
        print("长按")
    }
    //轻拍的方法
    func tapAction() {
        print("轻拍")
    }
