手势的识别

来源：互联网发布：网络人旗舰版编辑：程序博客网时间：2024/04/30 01:36

手势是可以通过代码或者在xib中直接拖进来来生成的

下面介绍动态使用代码来创建手势

import UIKitclass ViewController: UIViewController {           override func viewDidLoad() {        //点击事件        var atep = UITapGestureRecognizer(target: self, action: "tapDo:")        self.view.addGestureRecognizer(atep)        //单击的次数        atep.numberOfTapsRequired = 1        //拖动的事件        var aPan = UIPanGestureRecognizer(target: self, action: "handlenPan:")        self.view.addGestureRecognizer(aPan)        //最少手指的个数        aPan.minimumNumberOfTouches = 1        //最多的手指的个数        aPan.maximumNumberOfTouches = 3        //长按的事件        var aLongPress = UILongPressGestureRecognizer(target: self, action: "longPress:")        self.view.addGestureRecognizer(aLongPress)        //需要长按的时间 至少 0.5        aLongPress.minimumPressDuration = 0.5        //粘合事件        var aPinch =  UIPinchGestureRecognizer(target: self, action: "pinchDo:")        self.view.addGestureRecognizer(aPinch)        //旋转的事件                var aRotation = UIRotationGestureRecognizer(target: self, action: "rotationPiece:")        self.view.addGestureRecognizer(aRotation)        //清扫的事件 左清扫        var leftSwipe = UISwipeGestureRecognizer(target: self, action: "leftSwipe:")        self.view.addGestureRecognizer(leftSwipe)        leftSwipe.direction = UISwipeGestureRecognizerDirection.Left        //左右上下的清扫都一样                super.viewDidLoad()        // Do any additional setup after loading the view, typically from a nib.            }    //实现事件    func tapDo(sender:UITapGestureRecognizer) {        print("点击事件")    }       override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()        // Dispose of any resources that can be recreated.        //获取用户默认的函数               }}

可以用手势来进行模拟

还有很多信息具体可以看文档
