IOS7手势识别

//添加一个view 给view加上各种手势查看效果

gestureTestView.backgroundColor = [UIColor greenColor];

//开启UIVIew的事件响应

[self.view addSubview:gestureTestView];

//添加单击手势

UITapGestureRecognizer *tapOne = [[UITapGestureRecognizer alloc]init];

//设置响应事件的点击次数

tapOne.numberOfTapsRequired = 1;

//设置点击手指的个数

tapOne.numberOfTouchesRequired = 1;

//添加事件响应函数

[tapOne addTarget:self action:@selector(tapOneCallBack:)];

//把手势添加到view上

[gestureTestView addGestureRecognizer:tapOne];

//添加双击手势

UITapGestureRecognizer *tapTwo = [[UITapGestureRecognizer alloc]init];

//点击次数

tapTwo.numberOfTapsRequired = 2;

//事件响应函数

[tapTwo addTarget:self action:@selector(tapTwoCallBack:)];

//优先响应双击事件，双击时单击事件不识别

[tapOne requireGestureRecognizerToFail:tapTwo];

//把手势添加到View
