3、旋转手势
//旋转手势
UIRotationGestureRecognizer* rotaGR = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(rotaAction:)];
rotaGR.delegate = self;
//旋转手势回调方法
- (void)rotaAction:(UIRotationGestureRecognizer*)sender{
//通过手势的到旋转角度
float rota = sender.rotation;
//得到该手势作用的视图
UIView *view = sender.view;
//通过2D仿射变换函数中的旋转函数来使得当前视图旋转。
view.transform = CGAffineTransformRotate(view.transform, rota);
//复原
sender.rotation = 0;
}
4、平移手势
//平移手势
UIPanGestureRecognizer *panGP = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panAction:)];
//平移手势的回调方法
- (void)panAction:(UIPanGestureRecognizer*)sender{
//得到当前手势所在视图
UIView *view = sender.view;
//得到我们在视图上移动的偏移量
CGPoint currentPoint = [sender translationInView:view.superview];
//通过2D仿射变换函数中与位移有关的函数实现视图位置变化
view.transform = CGAffineTransformTranslate(view.transform, currentPoint.x, currentPoint.y);
//复原 // 每次都是从00点开始
[sender setTranslation:CGPointZero inView:view.superview];
}
5、边缘轻扫手势
//边缘轻扫手势
UIScreenEdgePanGestureRecognizer *edgePanGR = [[UIScreenEdgePanGestureRecognizer alloc] initWithTarget:self action:@selector(edgePanAction:)];
edgePanGR.edges = UIRectEdgeAll;
//边缘轻扫手势回调方法
- (void)edgePanAction:(UIScreenEdgePanGestureRecognizer*)sender{
NSLog(@"我成功的触发了屏幕边缘手势");
}
6、长按手势
// ⑥长按手势
UILongPressGestureRecognizer *longPressPR = [[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(longPressAction:)];
longPressPR.minimumPressDuration = 1;
// ⑥长按手势的回调方法
- (void)longPressAction:(UILongPressGestureRecognizer *)sender{
if (sender.state == UIGestureRecognizerStateEnded) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"看你麻痹" message:@"不服你咬死我" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];
[alertView show];
}
}
7、轻扫手势
// ⑦轻扫手势
UISwipeGestureRecognizer *swipeGR = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeAction:)];
// ⑦轻扫手势的回调方法
- (void)swipeAction:(UISwipeGestureRecognizer *)sender{
if (sender.state == UIGestureRecognizerStateEnded) {
UIActionSheet *actionSheet = [[UIActionSheet alloc]initWithTitle:@"槽尼玛" delegate:self cancelButtonTitle:@"纸张" destructiveButtonTitle:@"哈哈哈" otherButtonTitles:@"切毛毛", nil];
[actionSheet showInView:self.window];
}
}
