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");

　　}
