设置导航控件的标题

发布于 2024-12-09 02:08:13 字数 297 浏览 0 评论 0原文

我将基于窗口的应用程序转换为基于导航的应用程序，但我无法设置导航栏的标题。

controller = [[bookDisplayViewController alloc] initAndCreateView];

UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:controller];
nav.title=@"Application";
[window addSubview:nav.view];

原文

I converted window based application into navigation based but I am not able to set the title for the navigation bar.

controller = [[bookDisplayViewController alloc] initAndCreateView];

UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:controller];
nav.title=@"Application";
[window addSubview:nav.view];

您可以将其放入

self.navigationItem.title = @"YourName";

另一个视图的viewDidLoad中吗？我会尝试这种方式，看看它是否有效。

Is it possible for you to place

self.navigationItem.title = @"YourName";

in the viewDidLoad of the other view? I'd try it that way and see if it works.

您必须在 UIViewController 中设置标题。试试这个：


controller.navigationItem.title=@"Application";

事实上，苹果文档中 UINavigationItem 的“title”属性指出：

title
A localized string that represents the view that this controller manages.

@property(nonatomic, copy) NSString *title
Discussion
Subclasses should set the title to a human-readable string that represents the view to the user. If the receiver is a navigation controller, the default value is the top view controller’s title.

Availability
Available in iOS 2.0 and later.

You must set the title from within the UIViewController. Try this:


controller.navigationItem.title=@"Application";

Infact apple docs on UINavigationItem for the "title" property states that:

title
A localized string that represents the view that this controller manages.

@property(nonatomic, copy) NSString *title

Subclasses should set the title to a human-readable string that represents the view to the user. If the receiver is a navigation controller, the default value is the top view controller’s title.
