ios - 带有 UITabBarItem 的主从细节？

Question

可以在 UITabBarController 中嵌入分割 View Controller 吗？我在窗口的 appdelegate 中有一个 UITabBarController，我尝试向我的 Split View Controller 添加一个 segue，但是当我按下 DetailViewController 的相关选项卡时，它只显示一个空白屏幕？是否可以将分割 View Controller 作为选项卡 Controller 中的选项卡？

UISplitViewController 必须位于 Controller 层次结构的根部。来自 Apple 的 Split View Controllers文档:

A split view controller must always be the root of any interface you create. In other words, you must always install the view from a UISplitViewController object as the root view of your application’s window. The panes of your split view interface may then contain navigation controllers, tab bar controllers, or any other type of view controller you need to implement your interface. Split view controllers cannot be presented modally
