Answer 1

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:

Answer 2

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 ;)

Answer 3

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

Answer 4

[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.containerView cache:YES];

Answer 5

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.
