    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

        // Custom initialization

    }

    return self;

- (void)loadView

{

    self.rootView = [[[RootView alloc] initWithFrame:[UIScreen mainScreen].bounds] autorelease];

    self.rootView.ViewController = self;

    

    //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];

    

}
