轻拍手势
创建一个轻拍手势 同时绑定了一个事件
UITagpGestureRecognizer *aTapGR = [[UITapGestureRecognizer alloc] initWithTarget: self action:@selector(tapGRAction:)];
设置轻拍次数
aTapGR.numberOfTapsRequired = 1;
设置手指触摸的个数
aTapGR.numberOfTouchesRequired = 2;
添加手势
[self.rootView addGestureRecognizer:aTapGR];
[aTapGR release];
长按手势
UILongPressGestureRecognizer *longPressGR = [[UILongPressGestureRecognizer alloc] initWithTarget: self action:@selector(longPressAction:)];
[self.rootView addGestureRecognizer:longPressGR];
[longPressGR release];
旋转手势
UIRotationGestureRecognizer *rotationGR = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(rotationAction:)];
[self.rootView.testImageView addGestureRecognizer:rotationGR];
[rotationGR release];
捏合手势
UIPinchGestureRecognizer *pinchRG = [[UIPinchGestureRecognizer alloc] initWithTarget: self.action:@selector(pinchAction:)];
[self.rootView addGestureRecognizer:pinchRG];
[rotationGR release];
平移手势
UIPanGestureRecognizer *panGR = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panGRAction:)];
[self.rootView.testImageView addGestureRecognizer:panGR];
[panGR release];
轻扫手势
UISwipeGestureRecognizer *swipeGR = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeGRAction:)];
设置滑动方向
swipeGR.direction = UISwipeGestureRecognizerDirectionLeft; // 设置向左滑动
[self.rootView.testImageView addGestureRecognizer:swipeGR];
[swipeGR release];
