是否可以在ModalPopup中创建UINavigationController？

问题描述

您好，我有一个modalViewController，我弹出使用

Hi I have a modalViewController that I am popping up using

[self presentModalViewController:myController animated:YES];

我有一个事件发生在myController，我想导致另一个控制器被推到导航堆栈在myController的顶部（它再次被模态地呈现）。我如何做到这一点？

I have an event occurring within myController which I would like to result in another controller being pushed onto the navigation stack ON TOP OF myController (which again has been presented modally). How can I do this?

我已经在myController内尝试过以下操作：

I have tried the following from within myController:

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

这不起作用....

推荐答案

首先创建您的第二个modalViewController

First create your second modalViewController

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

然后像这样创建navigaitonController

then create navigaitonController like this

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

然后将您的navigationController显示为modalview控制器

then present your navigationController as modalview controller

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

在这里。希望它有帮助。

Here you go. Hope it helps.
