Tabbar 未显示在 XCode 的扩展视图中 [英] Tabbar is not showing in extended views in XCode

问题描述

！我是一个客观的 c 初学者.我已经在这个问题上研究了几个小时并观看了 youtube 视频，但仍然无法解决这个问题 - 我创建了标签栏控制器，第一个视图作为图片中显示的第一个标签.然后我尝试用另外两个视图扩展第一个视图:一个主表视图和一个详细信息 UIView.第一个视图通过第一个视图上的按钮链接到主表视图.我编译运行该项目，一切都很顺利，除了主表视图和详细信息 UIView 上没有显示标签栏.我试图添加标签栏项目，但仍然没有显示任何内容.我还检查了属性检查器以确保底部栏属性设置为推断"，我现在可以做什么?谢谢你的帮助.

! am an objective c beginner. I have researched hours on this issue and have watched youtube videos but still cant solve this problem - I have created tabbar controller with first view as the first tab as dispalyed in the pic. I then tried to extend the first view with two more views: one master table view and one detail UIView. The first view is linked to the master table view through the button on the first view. I compiled to run the project, everything is smooth except the tabbar is not showing on the master table view and detail UIView. I tried to add in the tabbar item, but still nothing is shown. I also checked the attribute inspectors to ensure the bottom bar property is set to "infered", what can i do now? thanks for your help.

推荐答案

Tab bar 控制器加载的视图控制器必须是 UINavigationController.查看您在此处上传的图片，我认为您的情况不会发生这种情况.下面的图片一定能帮助你理解我的观点.

The view controller loaded by the Tab bar controller must be a UINavigationController. Looking at the image that you have uploaded here I don't think that is happening in your case. The following image must help you understand my point.

一旦你像上面那样设置你的故事板，你的问题就会解决.

Once you set up your storyboard like above your problem will be solved.
