1.UITapGestureRecognizer 点击/双击手势
var tapGesture = UITapGestureRecognizer(target: self, action: "handleTapGesture:")
//设置手势点击数,双击：点2下
tapGesture.numberOfTapsRequired = 2
self.view.addGestureRecognizer(tapGesture)
2.UIPinchGestureRecognizer 捏 (放大/缩小)手势
var pinchGesture = UIPinchGestureRecognizer(target: self, action: "handlePinchGesture:")
self.view.addGestureRecognizer(pinchGesture)
3.UIRotationGestureRecognizer 旋转手势
var rotateGesture = UIRotationGestureRecognizer(target: self, action: "handleRotateGesture:")
self.view.addGestureRecognizer(rotateGesture)
4. UIPanGestureRecognizer 拖动手势
var panGesture = UIPanGestureRecognizer(target: self, action: "handlePanGesture:")
self.view.addGestureRecognizer(panGesture)
5. UISwipeGestureRecognizer 划动手势
var swipeGesture = UISwipeGestureRecognizer(target: self, action: "handleSwipeGesture:")
swipeGesture.direction = UISwipeGestureRecognizerDirection.Left //不设置是右
self.view.addGestureRecognizer(swipeGesture)
6. UILongPressGestureRecognizer 长按手势
var longpressGesutre = UILongPressGestureRecognizer(target: self, action: "handleLongpressGesture:")
//长按时间
// longpressGesutre.minimumPressDuration
//所需触摸次数
/// longpressGesutre.numberOfTouchesRequired
self.view.addGestureRecognizer(longpressGesutre)
UIGestureRecognizerState 枚举定义如下
enum UIGestureRecognizerState : Int {
case Possible // the recognizer has not yet recognized its gesture, but may be evaluating touch events. this is the default state
case Began // the recognizer has received touches recognized as the gesture. the action method will be called at the next turn of the run loop
case Changed // the recognizer has received touches recognized as a change to the gesture. the action method will be called at the next turn of the run loop
case Ended // the recognizer has received touches recognized as the end of the gesture. the action method will be called at the next turn of the run loop and the recognizer will be reset to UIGestureRecognizerStatePossible
case Cancelled // the recognizer has received touches resulting in the cancellation of the gesture. the action method will be called at the next turn of the run loop. the recognizer will be reset to UIGestureRecognizerStatePossible
case Failed // the recognizer has received a touch sequence that can not be recognized as the gesture. the action method will not be called and the recognizer will be reset to UIGestureRecognizerStatePossible
}
