我的iOS学习历程 - 手势

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

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

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

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

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

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

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];

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

}
