在transitionFromView期间缩放UIView？

发布于 2024-11-01 01:12:41 字数 530 浏览 0 评论 0原文

我使用容器 UIView 来复制 iTunes 商店在您点击专辑插图时的行为，它会翻转和缩放。

当前代码如下所示：

//mainView is 300x300x, smallView is 30x30      

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:2.0];
[UIView transitionFromView:mainView toView:smallView duration:3.0 options:UIViewAnimationOptionTransitionFlipFromLeft completion:nil];

containerView.frame = CGRectMake(275, 415, 30, 30);

[UIView commitAnimations];

我似乎无法在动画过程中缩放 containerView 的内容，框架只是靠近内容。我尝试对视图和图层以及其他一些东西应用一些转换，但我似乎无法让它正常运行。

I'm using a container UIView to replicate the kind of behavior the iTunes store does when you tap on album artwork and it flips and scales.

Current code looks like:

//mainView is 300x300x, smallView is 30x30      

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:2.0];
[UIView transitionFromView:mainView toView:smallView duration:3.0 options:UIViewAnimationOptionTransitionFlipFromLeft completion:nil];

containerView.frame = CGRectMake(275, 415, 30, 30);

[UIView commitAnimations];

I can't seem to get the content of the containerView to scale during the animation, the frame just closes in on the content. I tried applying some transforms to both the view and the layers and a bunch of other things but I can't seem to get it to behave properly.

不要设置框架，而是尝试使用变换：

- (void)setStartTransform:(CGAffineTransform)transform;
- (void)setEndTransform:(CGAffineTransform)transform;

类似的东西

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:2.0];
[UIView transitionFromView:mainView toView:smallView duration:3.0 options:UIViewAnimationOptionTransitionFlipFromLeft completion:nil];

//containerView.frame = CGRectMake(275, 415, 30, 30);

[containerView setStartTransform: CGAffineTransformIdentity];
[containerView setEndTransform: CGAffineTransformMakeScale(0.1, 0.1)];

[UIView commitAnimations];

（您可能也需要对变换应用翻译。）

Rather than setting the frame, try using a transform instead:

- (void)setStartTransform:(CGAffineTransform)transform;
- (void)setEndTransform:(CGAffineTransform)transform;

Something like

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:2.0];
[UIView transitionFromView:mainView toView:smallView duration:3.0 options:UIViewAnimationOptionTransitionFlipFromLeft completion:nil];

//containerView.frame = CGRectMake(275, 415, 30, 30);

[containerView setStartTransform: CGAffineTransformIdentity];
[containerView setEndTransform: CGAffineTransformMakeScale(0.1, 0.1)];

[UIView commitAnimations];

(You might need to apply a translate to the transform too.)

试试这样：

[UIView transitionWithView:mainView
           duration:0.2
           options:UIViewAnimationOptionTransitionFlipFromLeft
           animations:^{ 
              containerView.frame = CGRectMake(275, 415, 30, 30)
            }
           completion:NULL];

Try it this way:

[UIView transitionWithView:mainView
           duration:0.2
           options:UIViewAnimationOptionTransitionFlipFromLeft
           animations:^{ 
              containerView.frame = CGRectMake(275, 415, 30, 30)
            }
           completion:NULL];
