Core Animation: How to make a page flipping transition?

Question

I want to create a page flipping transition for an iPhone app like the one in notes. Basically when you go to a new view the bottom or top of the page curls like if you were turning the page of a book.

Anyone know of a tutorial on how to do this?

Answer 1

[UIView beginAnimations:@"pageCurlUp" context:NULL];
[UIView setAnimationDuration:0.5];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:someUIView cache:YES];
[UIView commitAnimations];

Also look for UIViewAnimationTransition in documentation.

Answer 2

Xcode provides a template to create an utility application, in which there is a Info button, and a flipside view. You might want to have a look at this template.

You can do the same by setting the modelTransitionStyle of the controller to UIModelTransitionStyleFlipHorizontal

FlipsideViewController *controller = [[FlipsideVewController alloc] initWithNibName:@"FlipsideView" bundle:nil];

controller.modelTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModelViewController: controller animated:YES];

[controller release];
