如何在 UIView 动画之前更新 UI

发布于 2024-10-03 17:28:21 字数 469 浏览 0 评论 0原文

我在程序中向 UIView 添加了一个动画。视图中有很多控件。我试图在动画之前隐藏一些控件，所以我将隐藏属性设置为YES。但它不起作用。在动画过程中它仍然在图层上可见。

这是一些代码：

button.hidden = YES;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0f];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES];
[UIView commitAnimations]

谁能告诉我如何在动画之前隐藏控件？或者如何更新控制雕像（控制位置，可见等）

谢谢

I add an animation to UIView in my program. There are many controls in the view. I tried to hide some controls before animation, so I set hidden property to YES. But it didn't work.It still visible on the layer during the animation.

here is some code:

button.hidden = YES;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0f];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES];
[UIView commitAnimations]

Could any one tell me how to hide controls before animation?
Or how to update control statues(control position, visible, etc)

thanks

如果您尝试为视图设置动画，则设置其新值的语句（例如（button.hidden = YES））应位于动画块内，如下所示。

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0f];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES];
button.hidden = YES;
[UIView commitAnimations];

If you're trying to animate a view, the statement that sets its new value, like (button.hidden = YES), should be located INSIDE your animation block, like so.

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0f];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES];
button.hidden = YES;
[UIView commitAnimations];
