如何在iPhone中制作像地图应用一样的半卷曲动画？

发布于 2024-09-01 17:22:37 字数 314 浏览 5 评论 0原文

我正在使用以下代码进行页面卷曲动画

[UIView beginAnimations:@"yourAnim" context:nil];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:yourView cache:cacheFlag];
...
[UIView commitAnimations];

是否可以制作像 iphone/ipod 上的maps.app 一样的半卷曲动画？

有什么想法如何做出类似的效果吗？

谢谢

I am using the following code for page curl animation

[UIView beginAnimations:@"yourAnim" context:nil];

Is it possible to make the half curl animation like the maps.app on iphone/ipod ?

Any ideas how to make an similar effect ?

Thanks

从 3.2 开始，Apple 确实支持模态视图的呈现。这是有道理的：卷页效果旨在向用户发出信号，表明正在显示选项或设置页面，并且当他们完成更改后，它们将被发送回原始视图。 Apple 不希望动画推断出页面层次结构正在进行的更改，而只是一种必须返回其起始位置的模态更改。

使用起来非常简单；只需确保您从全屏视图开始，并使用 UIModalPresentationFullScreen 样式加载，我认为这是默认样式。

通常在 UIView 4.0 中添加的动画过渡可以使用类似的效果，但这是使用该效果的直接方法。

simpleVC * myModalVC = [[simpleVC alloc] init];
[myModalVC setModalTransitionStyle:UIModalTransitionStylePartialCurl];
[myModalVC setDelegate:self];

[self presentModalViewController:myModalVC animated:YES];
[simpleVC release];

关于 UIModalTransitionStyle 常量的 Apple 文档链接

Apple does support this for the presentation of modal views as of 3.2. This makes sense: the page curl effect is intended to signal the user that a page of options or settings is being revealed, and when they are done changing things, they will be sent back to the original view. Apple doesn't want the animation to infer an ongoing change to the page hierarchy, just a modal one that must return to its starting place.

It's pretty straightforward to use; just be sure that you are starting from a full screen view, and loading with the UIModalPresentationFullScreen style, which I believe is the default.

There are animation transitions to use a similar effect in UIViews generally that were added as of 4.0, but this is a straightforward way to use the effect.

simpleVC * myModalVC = [[simpleVC alloc] init];
[myModalVC setModalTransitionStyle:UIModalTransitionStylePartialCurl];
[myModalVC setDelegate:self];

[self presentModalViewController:myModalVC animated:YES];
[simpleVC release];
