iPhone SDK 4 "Half curl page transition"

In Steve Jobs' keynote announcement of the iPhone SDK 4 earlier this year, one of t开发者_JAVA技巧he slides showed that a "Half curl page transition" was part of the new SDK.

I've looked through the iOS API docs and I can't seem to find this transition. Does anyone know where it is?

It's not a transition, but a modalTransitionStyle. You can check the docs here: https://developer.apple.com/documentation/uikit/uiviewcontroller/1621388-modaltransitionstyle

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.

Are you talking about iBook style page turning animations? There's a blog piece about it here, with links to 2 GitHub projects with it:

Have you try Manga Rock Unity? They have a page turning really like iBook, moving by fingers. Not private API I guess, or else they cannot be on.

Can ask how they do that ;)

you can checkout XBPageCurl project on github it also provide example how to do that
