Tab Bar on top of App in iOS instead of bottom, and customized?
提问by Jake Weso
Is there a way to customize the tab bar to be a custom design instead of how the iOS default design is, and have it at the top of the app instead of the bottom?
有没有办法将标签栏自定义为自定义设计，而不是 iOS 默认设计，并将其放在应用程序的顶部而不是底部？
Basically I have a custom design for tabs in the app we want to implement and it is on the top, looking similar to below:
基本上，我在我们想要实现的应用程序中对选项卡进行了自定义设计，它位于顶部，类似于下图：
Can I use the Tab Bar controller to achieve this, or do I just have to design it all in a normal view controller and just code everything myself to achieve it?
我可以使用 Tab Bar 控制器来实现这一点，还是我只需要在一个普通的视图控制器中设计它，然后自己编写所有代码来实现它？

You will have to do it custom. If you're doing this with storyboards I suggest looking for a tutorial on how to implement a vertical tab bar controller (like the one in the Twitter iPad app). There are a few examples out there.
你将不得不做定制。如果您使用情节提要来执行此操作，我建议您查找有关如何实现垂直标签栏控制器（如 Twitter iPad 应用程序中的控制器）的教程。有几个例子。

You need a custom container vc for the nav, and separate VC for each content area.
您需要一个用于导航的自定义容器 vc，并为每个内容区域使用单独的 VC。
