在故事板中使用自定义推送Segue

Question

在iPhone中,当我们在Storyboard中使用push Segue时,它总是导航right到left.我们可以实现它导航left到的任何机制right,还是down实现top？

我知道如何创建CustomSegue,但它不像是一样Push.你能帮助我吗？

如果您正在为iOS 5开发App,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];
}
