• swift 中手势的使用


    /**点击手势*/
    func tapGestureDemo() {
        //建立手势识别器
        let gesture = UITapGestureRecognizer(target: self, action: "viewTap:")
        //附加识别器到视图
        self.view1.addGestureRecognizer(gesture)
    }
    /**缩放手势*/
    func pinchGestureDemo() {
        //建立手势识别器
        let gesture = UIPinchGestureRecognizer(target: self, action: "viewPinch:")
        //附加识别器到视图
        self.view1.addGestureRecognizer(gesture)
    }
    /**旋转手势*/
    func rotationGestureDemo() {
        //建立手势识别器
        let gesture = UIRotationGestureRecognizer(target: self, action: "viewRotation:")
        //附加识别器到视图
        self.view1.addGestureRecognizer(gesture)
    }
    /**滑动手势*/
    func swipeGestureDemo() {
        //建立手势识别器
        let gesture = UISwipeGestureRecognizer(target: self, action: "viewSwipe:")
        //附加识别器到视图
        self.view1.addGestureRecognizer(gesture)
    }
    /**平移手势*/
    func panGestureDemo() {
        //建立手势识别器
        let gesture = UIPanGestureRecognizer(target: self, action: "viewPan:")
        //附加识别器到视图
        self.view1.addGestureRecognizer(gesture)
    }
    /**长按手势*/
    func LongPressGestureDemo() {
        //建立手势识别器
        let gesture = UILongPressGestureRecognizer(target: self, action: "viewLongPress:")
        //附加识别器到视图
        self.view1.addGestureRecognizer(gesture)
    }
    /**自定义手势*/
    func custonGestureDemo() {
        //建立手势识别器
        let gesture = CustomGestureRecognizer(target: self, action: "viewCustom:")
        //附加识别器到视图
        self.view1.addGestureRecognizer(gesture)
    }
    //-----------------------手势action事件---------------------------
    /**点击事件*/
    @IBAction func viewTap(sender: UITapGestureRecognizer) {
        print("clicked...")
    }
    /**缩放事件*/
    func viewPinch(sender: UIPinchGestureRecognizer) {
        print("pinch...")
        let _width = view1.bounds.width
        let _height = view1.bounds.height
        view1.bounds.size = CGSize( _width * sender.scale, height: _height * sender.scale)
    }
    /**旋转事件*/
    func viewRotation(sender: UIRotationGestureRecognizer) {
        view1.transform = CGAffineTransformMakeRotation(sender.rotation)
    }
    /**滑动事件*/
    var offsetX: CGFloat = 0
    func viewSwipe(sender: UISwipeGestureRecognizer) {
        if sender.direction == UISwipeGestureRecognizerDirection.Right {
            //每次向右平移20
            offsetX += 20
            view1.transform = CGAffineTransformMakeTranslation(offsetX, 0)
        }
    }
    /**平移事件*/
    func viewPan(sender: UIPanGestureRecognizer) {
        let _transX = sender.translationInView(view1).x
        let _transY = sender.translationInView(view1).y
        view1.transform = CGAffineTransformMakeTranslation(_transX, _transY)
    }
    /**长按事件*/
    func viewLongPress(sender: UILongPressGestureRecognizer) {
        print("long pressed....")
    }
    func viewCustom(sender: CustomGestureRecognizer) {
        print("custom gesture...")
    }
