推荐答案

而不是以下组织(您当前正在使用):

Rather than the following organization (which you're currently using):

NavController -> TabBarController -> ViewControllerA
                                  \
                                   -> ViewControllerB

您必须执行以下操作:

TabBarController -> NavControllerA -> ViewControllerA
                 \
                  -> NavControllerB -> ViewControllerB

UITabBarController s应该始终是根视图.每个子视图控制器都需要自己的导航控制器，以实现所需的导航栏+选项卡栏效果.这是一个结构外观的示例:

UITabBarControllers should always be the root view. Each child view controller needs its own navigation controller to achieve the navigation bar + tab bar effect you desire. Here is an example of what the structure should look like:

完成上述操作后，要将导航项/标题添加到每个视图控制器，请确保将导航项拖到每个视图控制器上.您可以在实用工具"视图底部的对象库"中找到导航项:

As for adding navigation items / titles to each view controller once you've done the above, make sure to drag Navigation Items onto each view controller. You can find the Navigation Item in the Object Library at the bottom of the Utilities view:
