我们在手机上可以用很多手势来触发不同的操作,今天就是学习怎样去添加手势

添加手势步骤

初始化手势添加手势触发调用的方法
把手势添加到视图上
释放手势
1.长按

    UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressAction:)];// 设置长按时间    longPress.minimumPressDuration = 2.0;    [imageView addGestureRecognizer:longPress];    [longPress release];

2.旋转

UIRotationGestureRecognizer *rotation = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(rotationAciton:)];    [imageView addGestureRecognizer:rotation];    [rotation release];

3.捏合

UIPinchGestureRecognizer *pinch = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(pinchAciton:)];    [imageView addGestureRecognizer:pinch];    [pinch release];

4.平移

UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panAction:)];    [imageView addGestureRecognizer:pan];    [pan release];

5.轻扫

UISwipeGestureRecognizer *swipe = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeAction:)];    swipe.direction = UISwipeGestureRecognizerDirectionLeft;    [imageView addGestureRecognizer:swipe];    [swipe release];

6.边缘扫

UIScreenEdgePanGestureRecognizer *screenEdgePan = [[UIScreenEdgePanGestureRecognizer alloc] initWithTarget:self action:@selector(screenEdgePanAction:)];// 设置下从哪个边缘开始扫    screenEdgePan.edges = UIRectEdgeRight;    [imageView addGestureRecognizer:screenEdgePan];    [screenEdgePan release];

每个手势添加的方法可以在下面自己写例如
实现轻拍方法:

- (void)tapAction:(UITapGestureRecognizer *)tap{       NSLog(@"你拍我了, 很轻");       UIImageView *imageView = (UIImageView *)tap.view;       imageView.image = [UIImage imageNamed:@"Highlighted"];}

这就是我们的手势学习了
