是否可以在ModalPopup中创建UINavigationController？

Question

嗨,我有一个我正在弹出的modalViewController

[self presentModalViewController:myController animated:YES];

我在myController中发生了一个事件,我希望将另一个控制器推送到导航堆栈ON TOP OF myController(它再次以模态方式呈现).我怎样才能做到这一点？

我在myController中尝试了以下内容:

UINavigationController* navController = [[UINavigationController alloc] initWithRootViewController:self];
  NewController* n = [[NewController alloc] init];
  [navController pushViewController:n animated:YES];
  [n release];

但这不起作用....

首先创建你的第二个modalViewController

NewController* new = [[NewController alloc] init];

然后像这样创建navigaitonController

UINavigationController* navigationController = [[UINavigationController alloc] initWithRootViewController: new];
navigationController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;

然后将您的navigationController呈现为模态视图控制器

[self presentModalViewController:navigationController animated:YES];
[navigationController release];

干得好.希望能帮助到你.
