iphone - 从左到右翻转 UIView pre-iOS 4

Question

我知道有一种简单的方法来实现它，但是你如何在 iOS 4 之前UIViewAnimationOptionTransitionFlipFromLeft做类似的事情（即翻转），例如在 .UIViewiPad

Answer 1

[UIView beginAnimations: @"flipOverCard1" context: nil];
[UIView setAnimationDuration: 0.5f];
[UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft forView: card1 cache: YES];

// Stuff to do while transitioning

[UIView commitAnimations];
