手势识别是具有互斥的原则的，比如单击和双击，如果它识别出一种手势，其后的手势将不被识别
// 添加单击的手势UITapGestureRecognize
UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] init];
[tapGestureRecognizer addTarget:self action:@selector(tapGestureAction:)]; // 添加点击手势的方法
[self.view addGestureRecognizer:tapGestureRecognizer]; // 添加到当前的View上
// 添加双击的手势UITapGestureRecognize
UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] init];
tapGestureRecognizer.numberOfTapsRequired = 2; // 设置单击几次才触发方法
[tapGestureRecognizer addTarget:self action:@selector(tapGestureAction:)]; // 添加点击手势的方法
[self.view addGestureRecognizer:tapGestureRecognizer]; // 添加到当前的View上
添加长按的手势UILongPressGestureRecognizer
注意：会调用两次方法，开始长按调用一次 松开后再调用一次 当长按并且滑动的时候，会多次调用长按的方法
UILongPressGestureRecognizer *pressLongGestureRecognizer = [[UILongPressGestureRecognizeralloc] init];
[pressLongGestureRecognizer addTarget:self action:@selector(pressLongGestureAction:)]; // 给长按手势添加方法
[self.view addGestureRecognizer:pressLongGestureRecognizer]; // 添加到当前的View上
添加捏合的手势UIPinchGestureRecognizer
注意：捏合手势不是捏合一次调用一次方法，而是在捏合的过程中不停的调用方法
UIPinchGestureRecognizer *pinchGestureRecognizer = [[UIPinchGestureRecognizer alloc] init];
[pinchGestureRecognizer addTarget:self action:@selector(pinchGestureAction:)]; // 添加捏合手势的方法
[self.view addGestureRecognizer:pinchGestureRecognizer]; // 添加到当前的View上
添加旋转的手势UIRotationGestureRecognizer
注意：旋转手势是两指同时进行旋转
UIRotationGestureRecognizer *rotationGestureRecognizer = [[UIRotationGestureRecognizeralloc] init];
[rotationGestureRecognizer addTarget:self action:@selector(rotationGestureAction:)]; // 给旋转手势添加方法
[self.view addGestureRecognizer:rotationGestureRecognizer]; // 添加到当前的View上
添加滑动的手势（轻扫手势） UISwipeGestureRecognizer
注意： 快速移动，是用于监测滑动的方向的
UISwipeGestureRecognizer *swipGestureRecognizer = [[UISwipeGestureRecognizer alloc] init];
swipGestureRecognizer.direction = UISwipeGestureRecognizerDirectionUp; // 添加手势的方法
// 以下是设置滑动的方向
// typedef NS_OPTIONS(NSUInteger, UISwipeGestureRecognizerDirection) {
// UISwipeGestureRecognizerDirectionRight = 1 << 0, // 从左向右滑动
// UISwipeGestureRecognizerDirectionLeft = 1 << 1, // 从右向左滑动
// UISwipeGestureRecognizerDirectionUp = 1 << 2, // 从下向上滑动
// UISwipeGestureRecognizerDirectionDown = 1 << 3 // 从上向下滑动
// };
[swipGestureRecognizer addTarget:self action:@selector(swipGestureAction:)]; // 给滑动手势添加方法
[self.view addGestureRecognizer:swipGestureRecognizer]; // 添加到当前的View上
添加拖移手势（平移手势） UIPanGestureRecognizer
注意：慢速移动，是用于监测偏移的量的
UIPanGestureRecognizer *panGestureRecognizer = [[UIPanGestureRecognizer alloc] init];
[panGestureRecognizer addTarget:self action:@selector(panGestureAction:)]; // 添加托移收拾的方法
[self.view addGestureRecognizer:panGestureRecognizer]; // 添加到当前的View
[panGestureRecognizer release], panGestureRecognizer = nil; // 释放内存
