 初始化手势同时添加手势事件---把手势添加到视图上

 // 1.轻拍手势类
    // 创建一个轻拍手势 同时绑定了一个事件
    UITapGestureRecognizer *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];


    // 2.长按手势
  UILongPressGestureRecognizer *longPressGR = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressAction:)];

    [self.rootView addGestureRecognizer:longPressGR];
    [longPressGR release];

    // 3.旋转手势
    UIRotationGestureRecognizer *rotationGR = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(rotationAction:)];
    [self.rootView.testImageView addGestureRecognizer:rotationGR];
    [rotationGR release];

    // 4.捏合手势
 UIPinchGestureRecognizer *pinchRG = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(pinchAction:)];
    [self.rootView addGestureRecognizer:pinchRG];
    [pinchRG release];

    // 5.平移手势

UIPanGestureRecognizer *panGR = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panGRAction:)];
    [self.rootView.testImageView addGestureRecognizer:panGR];
    [panGR release];

    // 6.轻扫手势
UISwipeGestureRecognizer *swipeGR = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeGRAction:)];

    // 设置滑动方向 默认是从左往右
    swipeGR.direction = UISwipeGestureRecognizerDirectionLeft; // 设置向左滑动

    [self.rootView.testImageView addGestureRecognizer:swipeGR];
    [swipeGR release];

    // 7.屏幕边缘轻扫识别器

    UIScreenEdgePanGestureRecognizer *screenPGR = [[UIScreenEdgePanGestureRecognizer alloc] initWithTarget:self action:@selector(screenEdgeGRAction:)];
    [self.rootView addGestureRecognizer:screenPGR];
    [screenPGR release];
