Using Custom Push Segue in Storyboard
提问by Ali
In iPhone, when we use push Segue in Storyboard, it always navigates from rightto left. Can we implement any mechanism that it navigates leftto right, or downto top?

I know about how to create CustomSegue, but it does not work the same like Push. Can you help me?

If you are developing an App for iOS 5, you can create a class that implement UIStoryboardSegue (to have custom segue), and then override the Performmethod in this way:
如果您正在为 iOS 5 开发应用程序，您可以创建一个实现 UIStoryboardSegue 的类（具有自定义 segue），然后Perform以这种方式覆盖该方法：
-(void)perform {
UIViewController *sourceViewController = (UIViewController*)[self sourceViewController];
UIViewController *destinationController = (UIViewController*)[self destinationViewController];
CATransition* transition = [CATransition animation];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromLeft;
[sourceViewController.navigationController.view.layer addAnimation:transition forKey:kCATransition];
[sourceViewController.navigationController pushViewController:destinationController animated:NO];
}
