How to create a page curl animation?

Question

Any way to emulate something like this? Isn't there an API for doing something like a "Half page curl" or something?

Answer 1

controller.modalTransitionStyle = UIModalTransitionStylePartialCurl;
[self presentModalViewController:controller animated:YES];

UIModalTransitionStyle Transition styles available when presenting view controllers modally. The below are the four different transition styles. The "UIModalTransitionStylePartialCurl" is the one you're after.

typedef enum {
    UIModalTransitionStyleCoverVertical,
    UIModalTransitionStyleFlipHorizontal,
    UIModalTransitionStyleCrossDissolve,
    UIModalTransitionStylePartialCurl,
} UIModalTransitionStyle;
