将UITabBarController添加到UIViewController [英] Adding UITabBarController to a UIViewController

问题描述

我的应用程序目前有 UINavigationController ，我想在按钮的某个时刻按 UITabBarController 点击。我试图在Interface Builder上创建它（而不是以编程方式）。

My app currently has a UINavigationController and I'd like to push a UITabBarController at some point when a button is clicked. I am trying to create it on Interface Builder (as opposed to programatically).

所有在线教程都展示了如何创建基于标签栏的应用程序，其中涉及拖动 UITabBarController 进入 MainWindow.xib 这显然不是我想要的。

All online tutorials show how to create a tab bar based app, which involves dragging a UITabBarController into the MainWindow.xib which is obviously not what I want.

我所做的是创建 UIViewController 及其nib文件，拖动 UITabBarController 。现在将 UIViewController 推送到导航控制器将显示一个空视图（其空视图）。删除视图控制器中的视图会使应用程序崩溃。如何告诉 UIViewController 加载 UITabBarController 而不是自己的视图？

What I did was create a UIViewController, and its nib file, dragged a UITabBarController. Now pushing that UIViewController to the navigation controller will show an empty view (its empty view). Removing the view in the view controller will crash the app. How can I tell the UIViewController to load a UITabBarController instead of its own view?

对于那些投票给我的人：至少提供评论是不错的。问题不是一个糟糕的问题。问题是询问如何以非正统的方式使用UITabBarController的建议。我尝试了大部分建议而且没有用。如果你是投票，至少写一个评论。

推荐答案

问题是，因为我相信我已经提到过某个地方，就是XIB没有连接到它的UIView。当在XIB文件中删除UIView并添加UITabBarController时，XIB的视图属性必须连接到 UITabBarController 的观点。我连接它，它工作。这就是我获得SIGTRAP的原因。

The problem was, as I believe I've mentioned somewhere, is that the XIB does not have a UIView connected to it. When the UIView is deleted in a XIB file and a UITabBarController is added, the view property of the XIB has to be connected to the UITabBarController's view. I connected it and it worked. That was the reason why I was getting a SIGTRAP.
