Question

我有一个带有5个子视图控制器的标签ViewController（A）（B）我想从我的一个子视图控制器传递到我的故事板中的另一个视图控制器（C））

我在子视图控制器（B）中创建了一个按钮并将其链接到我的（C），并在我的故事板中推送，但是当我点击它时，这就是我得到的：

Answer 1

您应该添加UINavigationControllers作为标签，并使用ViewControllers（B）作为这些导航控制器的根。只有这样才能执行push。否则，您必须使用模态演示文稿，它将部分或全部覆盖您的Tab栏控制器。

从子Viewcontroller（Tab）传递到视图控制器
