在我的滚动视图中,我有多个图像视图,当用户点击 LONGPRESS 时,我可以移动每个图像视图,我已经这样做了,
UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(moveImage:)];
[panGesture setMaximumNumberOfTouches:2];
[panGesture setDelegate:self];
[imageview addGestureRecognizer:panGesture];
UILongPressGestureRecognizer *longPressRecognizer = [[UILongPressGestureRecognizer alloc] init];
[imageview addGestureRecognizer:longPressRecognizer];
- (BOOL) gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
return YES;
}
- (void)adjustAnchorPointForGestureRecognizer:(UIGestureRecognizer *)gestureRecognizerv {
if (gestureRecognizer.state == UIGestureRecognizerStateBegan) {
UIView *piece = gestureRecognizerv.view;
CGPoint locationInView = [gestureRecognizerv locationInView:piece];
CGPoint locationInSuperview = [gestureRecognizerv locationInView:piece.superview];
piece.layer.anchorPoint = CGPointMake(locationInView.x / piece.bounds.size.width, locationInView.y / piece.bounds.size.height);
piece.center = locationInSuperview;
}
}
- (void)moveImage:(UIPanGestureRecognizer *)gestureRecognizerg
{
NSLog(@"sdfgdsgsdg");
UIView *piece = [gestureRecognizerg view];
[self adjustAnchorPointForGestureRecognizer:gestureRecognizerg];
// need to test if the scrollview is already using the touches. If it is, leave them
if (!galleryView.tracking) {
if ([gestureRecognizerg state] == UIGestureRecognizerStateBegan || [gestureRecognizerg state] == UIGestureRecognizerStateChanged) {
CGPoint translation = [gestureRecognizerg translationInView:[piece superview]];
[piece setCenter:CGPointMake([piece center].x + translation.x, [piece center].y + translation.y)];
[gestureRecognizerg setTranslation:CGPointZero inView:[piece superview]];
}
}
}
在这里,我的问题是IMAGEVIEW 正在移动 scollview 中的每个位置,我需要重新排列视图,例如画廊视图。
