IOS UIGestureRecognizer

手势的添加以及实现：

- (void)viewDidLoad

{   

    [superviewDidLoad];

   //单击手势

   UITapGestureRecognizer *singleTap = [[UITapGestureRecognizeralloc] initWithTarget:selfaction:@selector(singleTap:)];

    [self.viewaddGestureRecognizer:singleTap];

    

   //双击手势

   UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizeralloc] initWithTarget:selfaction:@selector(doubleTap:)];

    doubleTap.numberOfTapsRequired =2;

    [self.viewaddGestureRecognizer:doubleTap];

    [singleTaprequireGestureRecognizerToFail:doubleTap];//先满足双击，不是双击就满足单击

    

   //长按手势

   UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizeralloc] initWithTarget:selfaction:@selector(longPress:)];

    longPress.numberOfTouchesRequired =1;

    longPress.allowableMovement =YES;

    longPress.minimumPressDuration =3;

    [self.viewaddGestureRecognizer:longPress];

    

   //滑动手势

   UISwipeGestureRecognizer *swipeGesture = [[UISwipeGestureRecognizeralloc] initWithTarget:selfaction:@selector(swipeGesture:)];

    swipeGesture.direction =UISwipeGestureRecognizerDirectionUp;//向上滑动

    [self.viewaddGestureRecognizer:swipeGesture];

    

   //旋转手势

   UIRotationGestureRecognizer *rotationGesture = [[UIRotationGestureRecognizeralloc]initWithTarget:selfaction:@selector(rotationGesture:)];

    [self.viewaddGestureRecognizer:rotationGesture];

    

    //二指往内或外拨动

   UIPinchGestureRecognizer *pinchGesture = [[UIPinchGestureRecognizeralloc] initWithTarget:selfaction:@selector(pinchGesture:)];

    [self.viewaddGestureRecognizer:pinchGesture];

    

   //拖动手势

   UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizeralloc] initWithTarget:selfaction:@selector(panGesture:)];

    [self.viewaddGestureRecognizer:panGesture];

    [panGesture requireGestureRecognizerToFail:swipGesture];//先满足滑动

}

- (void)singleTap:(UIGestureRecognizer *)sender

{

   NSLog(@"singeTap");

}

- (void)doubleTap:(UIGestureRecognizer *)sender

{

   NSLog(@"doubleTap");

}

- (void)longPress:(UIGestureRecognizer *)sender

{

   NSLog(@"longPress");

}

- (void)swipeGesture:(UIGestureRecognizer *)sender

{

   NSLog(@"swipeGesture");

}

- (void)rotationGesture:(UIGestureRecognizer *)sender

{

   NSLog(@"rotation");

}

- (void)pinchGesture:(UIGestureRecognizer *)sender

{

   NSLog(@"pinch");

}

- (void)panGesture:(UIGestureRecognizer *)sender

{

    NSLog(@"pan");

}
