1.轻击手势（TapGestureRecognizer）的添加
初始化代码TapGestureRecongnizer的代码如下：
1 //新建tap手势
2 UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapGesture:)];
3 //设置点击次数和点击手指数
4 tapGesture.numberOfTapsRequired = 1; //点击次数
5 tapGesture.numberOfTouchesRequired = 1; //点击手指数
6 [self.view addGestureRecognizer:tapGesture];
在回调方法中添加相应的业务逻辑：
1 //轻击手势触发方法
2 -(void)tapGesture:(id)sender
3 {
4 //轻击后要做的事情
5 }
2.长按手势（LongPressGestureRecognizer）
初始化代码：
//添加长摁手势
2 UILongPressGestureRecognizer *longPressGesture = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressGesture:)];
3 //设置长按时间
4 longPressGesture.minimumPressDuration = 0.5; //(2秒)
5 [self.view addGestureRecognizer:longPressGesture];
在对应的回调方法中添加相应的方法（当手势开始时执行）：
1 //常摁手势触发方法
2 -(void)longPressGesture:(id)sender
3 {
4 UILongPressGestureRecognizer *longPress = sender;
5 if (longPress.state == UIGestureRecognizerStateBegan)
6 {
7 UIAlertView *alter = [[UIAlertView alloc] initWithTitle:@“提示” message:@“长按触发” delegate:nil cancelButtonTitle:@“取消” otherButtonTitles: nil];
8 [alter show];
9 }
0 }
代码说明：手势的常用状态如下
开始：UIGestureRecognizerStateBegan
改变：UIGestureRecognizerStateChanged
结束：UIGestureRecognizerStateEnded
取消：UIGestureRecognizerStateCancelled
失败：UIGestureRecognizerStateFailed
3.轻扫手势（SwipeGestureRecognizer）
在初始化轻扫手势的时候得指定轻扫的方向，上下左右。 如果要要添加多个轻扫方向，就得添加多个轻扫手势，不过回调的是同一个方法。
添加轻扫手势，一个向左一个向右，代码如下：
1 //添加轻扫手势
2 UISwipeGestureRecognizer *swipeGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeGesture:)];
3 //设置轻扫的方向
4 swipeGesture.direction = UISwipeGestureRecognizerDirectionRight; //默认向右
5 [self.view addGestureRecognizer:swipeGesture];
6
7 //添加轻扫手势
8 UISwipeGestureRecognizer *swipeGestureLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeGesture:)];
9 //设置轻扫的方向
10 swipeGestureLeft.direction = UISwipeGestureRecognizerDirectionLeft; //默认向右
11 [self.view addGestureRecognizer:swipeGestureLeft];
回调方法如下：
1 //轻扫手势触发方法
2 -(void)swipeGesture:(id)sender
3 {
4 UISwipeGestureRecognizer *swipe = sender;
5 if (swipe.direction == UISwipeGestureRecognizerDirectionLeft)
6 {
7 //向左轻扫做的事情
8 }
9 if (swipe.direction == UISwipeGestureRecognizerDirectionRight)
10 {
11 //向右轻扫做的事情
12 }
13 }
14
4.捏合手势（PinchGestureRecognizer）
捏合手势初始化
//添加捏合手势
2 UIPinchGestureRecognizer *pinchGesture = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(pinchGesture:)];
3 [self.view addGestureRecognizer:pinchGesture];
捏合手势要触发的方法（放大或者缩小图片）：
1 ////捏合手势触发方法
2 -(void) pinchGesture:(id)sender
3 {
4 UIPinchGestureRecognizer *gesture = sender;
5
6 //手势改变时
7 if (gesture.state == UIGestureRecognizerStateChanged)
8 {
9 //捏合手势中scale属性记录的缩放比例
10 _imageView.transform = CGAffineTransformMakeScale(gesture.scale, gesture.scale);
11 }
12
13 //结束后恢复
14 if(gesture.state==UIGestureRecognizerStateEnded)
15 {
16 [UIView animateWithDuration:0.5 animations:{
17 _imageView.transform = CGAffineTransformIdentity;//取消一切形变
18 }];
19 }
20 }
5.拖动手势（PanGestureRecognizer）
拖动手势的初始化
//添加拖动手势
2 UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panGesture:)];
3 [self.view addGestureRecognizer:panGesture];
拖动手势要做的方法（通过translationInView获取移动的点，和TouchesMoved方法类似）
1 //拖动手势
2 -(void) panGesture:(id)sender
3 {
4 UIPanGestureRecognizer *panGesture = sender;
5
6 CGPoint movePoint = [panGesture translationInView:self.view];
7
8 //做你想做的事儿
9 }
6.旋转手势（RotationGestureRecognizer）
旋转手势的初始化
//添加旋转手势
2 UIRotationGestureRecognizer *rotationGesture = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(rotationGesture:)];
3 [self.view addGestureRecognizer:rotationGesture];
旋转手势调用的方法：
复制代码
1 //旋转手势
2 -(void)rotationGesture:(id)sender
3 {
4
5 UIRotationGestureRecognizer *gesture = sender;
6
7 if (gesture.state==UIGestureRecognizerStateChanged)
8 {
9 _imageView.transform=CGAffineTransformMakeRotation(gesture.rotation);
10 }
11
12 if(gesture.state==UIGestureRecognizerStateEnded)
13 {
14
15 [UIView animateWithDuration:1 animations:{
16 _imageView.transform=CGAffineTransformIdentity;//取消形变
17 }];
18 }
19
20 }
