IOS常用手势用法

target参数指的是给谁用手势，入button,view等

//1.单击

UITapGestureRecognizer *singleTapGR=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(singleTap:)];

[self.buttonView addGestureRecognizer:singleTapGR];

　　- (void)singleTap:(UITapGestureRecognizer *)tap

　　{

　　NSLog(@"单击");

　　}

//2.双击

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

doubleTap.numberOfTapsRequired=2;

[self.buttonView addGestureRecognizer:doubleTap];

//区别单击双击

[singleTapGR requireGestureRecognizerToFail:doubleTap];

//双击点击事件

-(void)doubleTap:(UITapGestureRecognizer *)taggestrue

{

NSLog(@"双击");

}

//3.轻扫

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

//设置轻扫方向,默认向右

swipeGesture.direction=UISwipeGestureRecognizerDirectionDown;

[self.view addGestureRecognizer:swipeGesture];

　　//轻扫事件

　-(void)swipe:(UISwipeGestureRecognizer *)swipeGesture

　{

　NSLog(@"轻扫手势");

　}

//4.平移

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

[self.view addGestureRecognizer:panGesture];

　　-(void)pan:(UIPanGestureRecognizer *)pan

　　{

　　CGPoint point=[pan locationInView:self.view];

　　 NSLog(@"%@",NSStringFromCGPoint(point));

　　}

//5.长按

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

longPressGesture.minimumPressDuration=1;

[self.buttonView addGestureRecognizer:longPressGesture];

　　-(void)longPress:(UILongPressGestureRecognizer *)longPress

　　{

　　//长按离开时一会调用一次,所以需要设置手势状态

　　 if(longPress.state==UIGestureRecognizerStateEnded)

　　{

　　NSLog(@"UIGestureRecognizerStateEnded");

　　return;

　　}

　　NSLog(@"长按超过两秒");

　　}
