UINavigationBar 拒绝在模态视图控制器中显示

我在 RootViewController 中使用以下代码加载模态视图控制器：

[self.navigationController presentModalViewController:accountViewController animated:YES];

在 accountViewController xib 文件中，我设置了一个导航栏。我的 MainWindow.xib 和 RootViewController.xib 也正确设置了导航栏。此外，我的应用程序委托已正确设置导航控制器（我假设）：

UINavigationController *aNavigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController];
self.navigationController = aNavigationController;

[window addSubview:navigationController.view];

但是，当我加载 accountViewController 时，UINavigationBar 无处可见。是否无法在模态视图中显示 UINavigationBar？我打算用它来隐藏后退按钮，并添加一个右键......

I am loading a Modal view controller using the following code in my RootViewController:

[self.navigationController presentModalViewController:accountViewController animated:YES];

In the accountViewController xib file, I have set a navigation bar. My MainWindow.xib and RootViewController.xib also have the navigation bar setup correctly. Additionally, my app delegate has setup the navigation controller (I assume) correctly:

UINavigationController *aNavigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController];
self.navigationController = aNavigationController;

[window addSubview:navigationController.view];

However, when I load my accountViewController the UINavigationBar is nowhere to be seen. Is it not possible to show a UINavigationBar in a modal view? I was planning to use it to hide the back button, and add a right button...

sha的答案是正确的，但我给出了我自己的答案，并用代码示例对其进行了扩展，以使其清楚。

你可能想要这样的东西：

- (void)showAccountViewController
{
    AccountViewController* accountViewController = [[AccountViewController alloc] initWithNibName:@"AccountView" bundle:nil];
    ...
    // Initialize properties of accountViewController
    ...
    UINavigationController* navController = [[UINavigationController alloc] initWithRootViewController:accountViewController];
    [self.navigationController presentModalViewController:navController animated:YES];
    [navController release];
    [accountViewController release];
}

sha's answer is correct, but I'm giving my own answer to expand on it with a code example to make it clear.

You probably want something like:

- (void)showAccountViewController
{
    AccountViewController* accountViewController = [[AccountViewController alloc] initWithNibName:@"AccountView" bundle:nil];
    ...
    // Initialize properties of accountViewController
    ...
    UINavigationController* navController = [[UINavigationController alloc] initWithRootViewController:accountViewController];
    [self.navigationController presentModalViewController:navController animated:YES];
    [navController release];
    [accountViewController release];
}
