UITabbarController 的“完成"隐藏在 UINavigationController 后面的按钮 [英] UITabbarController's "Done" button hidden behind UINavigationController

问题描述

我正在使用 Xcode 4.2 构建一个项目，我也在使用 Storyboard.所以基本上，我有一个 UINavigationcontroller，它是我的初始视图，连接到我的主菜单"视图.在我的主菜单"中，我有一个链接到标签栏控制器的按钮，它有 20 个标签.因此，会出现更多"按钮，单击更多"按钮时会出现编辑"按钮.一切正常，但我遇到的唯一问题是，一旦我单击编辑，配置页面就会向上滑动，并且完成"按钮隐藏在导航栏后面.无论如何，我可以将配置页面向上滑动到导航栏的前面吗?

I'm building a project using Xcode 4.2 and I'm also using the Storyboard. So basically, I have a UINavigationcontroller which is my initial view, connected to my "Main Menu" view. Inside my "Main Menu" I have a button that is linked to a tabbar controller, which has like 20 tabs. Therefore, a "More" button appears and when the "more" button is clicked an "edit" button appears. Everything works fine, but the only problem I have is that once I click edit, the configure page slides up and the "done" button is hidden behind the Navigation bar. Anyway I can the configure page slide up infront of the Navigation bar ?

此外，我使用了 Xcode 4.2 的新功能.您可以在编辑器工具栏下嵌入 NavigationController"和嵌入 TabbarController".谢谢 ！

Also, I used the Xcode 4.2's new feature. Where you can "Embed in NavigationController" and "Embed in TabbarController" under the Editor Toolbar. Thank you !

推荐答案

UITabBarController 的实例应该只作为窗口的根视图控制器.将 UITabBarController 放在另一个容器视图控制器中，例如 UINavigationController，可能会导致未定义的行为.

An instance of UITabBarController should only ever be the root view controller of your window. Placing a UITabBarController inside another container view controller, like UINavigationController, can lead to undefined behavior.

来自 UITabBarController 类参考...

From the UITabBarController Class Reference...

因为 UITabBarController 类继承自UIViewController 类，标签栏控制器有自己的视图可以通过 view 属性访问.部署标签栏时界面，您必须将此视图安装为窗口的根目录.与其他视图控制器不同，标签栏界面不应该作为另一个视图控制器的子级安装.

Because the UITabBarController class inherits from the UIViewController class, tab bar controllers have their own view that is accessible through the view property. When deploying a tab bar interface, you must install this view as the root of your window. Unlike other view controllers, a tab bar interface should never be installed as a child of another view controller.
