在 MonoTouch 选项卡式应用程序中显示标题
也许我错过了一些超级简单的东西，但我似乎无法在基本选项卡式应用程序中包含的视图顶部显示标题。我按照以下步骤操作...
- 新解决方案、通用情节提要、选项卡式应用程序
- 运行该应用程序，您将有两个基本视图“第一个视图”和“第二个视图”。
- 默认情况下，这两个视图都没有标题栏，但默认代码显示设置
this.Title。
为什么标题栏不显示？我如何让他们展示？我尝试了几种方法来显示这些内容，例如...
- 将界面生成器中的“顶部栏”设置为“导航栏”。然后它会显示在 Interface Builder 中，但不会在运行时显示。
- 我还尝试在 ViewDidLoad() 中设置 this.TabBarController.Title 但这似乎也没有做任何事情。
想法？
Maybe I'm missing something super simple, but I can't seem to get a title to show up at the top of Views contained within a basic tabbed application. I follow these steps...
- New Solution, Universal Storyboard, Tabbed Application
- Run that and you have two basic Views "First View" and "Second View".
- Neither View by default has a title bar, but the default code shows setting a
this.Title.
Why don't the title bars show up? How do I get them to show? I've tried several things to get these to show such as...
- Setting "Top Bar" in Interface Builder to "Navigation Bar". It then shows in Interface Builder but never shows on runtime.
- I've also tried in
ViewDidLoad()to setthis.TabBarController.Titlebut that doesn't seem to do anything either.
Thoughts?

您正在寻找的功能称为导航栏，如果没有与之关联的导航控制器，则可以通过 IB 手动将其添加到您的视图中。如果有导航控制器，那么导航栏将自动显示。
因此，要回答您的问题，如果您想要一个导航栏，请转到 IB 并从对象库中添加一个导航栏，然后您应该能够将导航栏上的标题操作为您心中的内容。
The feature you are looking for is called a NavigationBar and can be added manually via IB to your view if it does not have a NavigationController associated with it. If there is a navigation controller then the NavigationBar will show up automatically.
So to answer your question if you want a NavigationBar go to IB and add one from the objects library you should then be able to manipulate the Title on the nav bar to your hearts content.
