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...")
}
