//UIGestureRecognizer 手势识别的抽象类，一般情况不去使用它，而是去使用他的七个子类

//1. 轻拍手势类

//创建一个轻拍手势，同时绑定事件

// UITapGestureRecognizer *aTapGR = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapGRAction:)];

// //设置轻拍次数

//// aTapGR.numberOfTapsRequired = 3;

// //设置手指触摸的个数

// aTapGR.numberOfTouchesRequired = 2;

// //添加手势

// [self.rootView addGestureRecognizer:aTapGR];

//2.长按手势

// UILongPressGestureRecognizer *longpressGR = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longGRAction:)];

// [self.rootView addGestureRecognizer:longpressGR];

// [longpressGR release];

//3.旋转手势

// UIRotationGestureRecognizer *rotationGR = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(rotatationGRAction:)];

// [self.rootView.opeImageView addGestureRecognizer:rotationGR];

//4 捏合手势

// UIPinchGestureRecognizer *poinchGR = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(poinchGRAction:)];

// [self.rootView.opeImageView addGestureRecognizer:poinchGR];

// [poinchGR release];

// //5. 平移手势

// UIPanGestureRecognizer *panGR = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(panGRAction:)];

// [self.rootView.opeImageView addGestureRecognizer:panGR];

// [panGR release];

//6. 轻扫手势

UISwipeGestureRecognizer *swipeGR = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swiprGRAction:)];

//设置滑动方向

swipeGR.direction = UISwipeGestureRecognizerDirectionDown;

[self.rootView.opeImageView addGestureRecognizer:swipeGR];

[swipeGR release];

//7 屏幕边缘轻扫证书

UIScreenEdgePanGestureRecognizer *seGR = [[UIScreenEdgePanGestureRecognizer alloc]initWithTarget:self action:@selector(seGRAction:)];

[self.rootView.opeImageView addGestureRecognizer:seGR];

[seGR release];

}
