问题描述
在Steve Jobs今年早些时候的iPhone SDK 4的主题演讲中，其中一张幻灯片显示，半卷曲页面转换是新SDK的一部分：
In Steve Jobs' keynote announcement of the iPhone SDK 4 earlier this year, one of the slides showed that a "Half curl page transition" was part of the new SDK:
我浏览过iOS API docs和我似乎找不到这个转换。
I've looked through the iOS API docs and I can't seem to find this transition. Does anyone know where it is?
推荐答案
这不是一个转换，而是一个 modalTransitionStyle 。您可以在这里查看文档： http://developer.apple.com/iphone/library/documentation/uikit/reference/UIViewController_Class/Reference/Reference.html#//apple_ref/occ/instp/UIViewController/modalTransitionStyle a>
It's not a transition, but a modalTransitionStyle. You can check the docs here: http://developer.apple.com/iphone/library/documentation/uikit/reference/UIViewController_Class/Reference/Reference.html#//apple_ref/occ/instp/UIViewController/modalTransitionStyle
如果您创建了一个新的 UIViewController ，请设置 modalTransitionStyle 到 UIModalTransitionStylePartialCurl ，然后 presentModalViewController：animated：，你会得到所需的半卷曲页效果。
If you create a new UIViewController, set its modalTransitionStyle to UIModalTransitionStylePartialCurl, and then presentModalViewController:animated: it, you'll get the desired "half curl page" effect.
