iOS手势

七种手势，下面就是我的项目中写的，直接往ViewController.m里粘贴就行了，可以自己看运行结果。

@implementation ViewController

- (void)viewDidLoad {

[super viewDidLoad];

// Do any additional setup after loading the view, typically from a nib.

//一个控件可以绑定多个手势，但有些时候手势会右冲突。比如点击一次和点击二次

//手势 苹果封装好的一些事件类型，方便我们进行不同事件的处理

//Gesture手势    Recognizer识别

//UIGestureRecognizer手势父类是一个抽象类，需要子类完成一些功能

//    UITapGestureRecognizer;点击手势

//    UIPanGestureRecognizer;滑动

//    UIRotationGestureRecognizer;旋转

//    UIPinchGestureRecognizer;缩放

//    UILongPressGestureRecognizer;长按

//    UIScreenEdgePanGestureRecognizer;边缘滑动

//    UISwipeGestureRecognizer;轻扫

//可以给指定的控件添加手势，而不像touchbegan 事件的处理方式

UIView *bgView=[[UIView alloc]initWithFrame:CGRectMake(100, 100, 150, 200)];

bgView.backgroundColor=[UIColor redColor];

[self.view addSubview:bgView];

//点击手势

//创建点击手势并且绑定触发事件

UITapGestureRecognizer *tapgestureRecognizer=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapGesture:)];

//双击事件  连点2次

//tapgestureRecognizer.numberOfTapsRequired=2;

//触摸手指的个数

//tapgestureRecognizer.numberOfTouchesRequired=2;

//给bgView添加手势对象

[bgView addGestureRecognizer:tapgestureRecognizer];

//双击

UITapGestureRecognizer *tapgestureRecognizer2=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapGesture2:)];

tapgestureRecognizer2.numberOfTapsRequired=2;

[bgView addGestureRecognizer:tapgestureRecognizer2];

//单击 等待双击失败 才执行

[tapgestureRecognizer requireGestureRecognizerToFail:tapgestureRecognizer2];

//滑动手势 手指一直在屏幕上触摸移动

UIPanGestureRecognizer *panGesture=[[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(panGesture:)];

[bgView addGestureRecognizer:panGesture];

//旋转手势

UIRotationGestureRecognizer *rotationGesture=[[UIRotationGestureRecognizer alloc]initWithTarget:self action:@selector(rotationGesture:)];

[bgView addGestureRecognizer:rotationGesture];

//缩放

UIPinchGestureRecognizer *pinchGesture=[[UIPinchGestureRecognizer alloc]initWithTarget:self action:@selector(pinchGesture:)];

[bgView addGestureRecognizer:pinchGesture];

//长按

UILongPressGestureRecognizer *longGesture=[[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(longGesture:)];

[bgView addGestureRecognizer:longGesture];

//边缘滑动

UIScreenEdgePanGestureRecognizer *screenGesture=[[UIScreenEdgePanGestureRecognizer alloc]initWithTarget:self action:@selector(screenGesture:)];

screenGesture.edges=UIRectEdgeLeft;

[self.view addGestureRecognizer:screenGesture];

//轻扫

UISwipeGestureRecognizer *swipeGesture=[[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeGesture:)];

//默认往右轻扫

swipeGesture.direction=UISwipeGestureRecognizerDirectionLeft;

[bgView addGestureRecognizer:swipeGesture];

}

//所有事件都有状态 比如：开始 变化 结束 失败

/*

UIGestureRecognizerStatePossible, 默认状态：手势在未识别时的状态

UIGestureRecognizerStateBegan,    开始：手势触发时

UIGestureRecognizerStateChanged,  改变：手势变化时

UIGestureRecognizerStateEnded,    结束

UIGestureRecognizerStateCancelled,取消

UIGestureRecognizerStateFailed,  失败
