其他ViewController中的选项卡栏控制器方法和属性

Question

I have been looking around and I can't find any clear answers. How can I access methods and properties written in the TabBarController from a ViewController attached to it?

The TabBarController has ViewControllers A and B attached to it. VCA has VA1, and VCB has VC2 each connected by a segue. How can I allow VC1 to use methods and properties found on TabBarController.

在这种情况下，可以通过子VC的parentViewController来访问选项卡栏控制器，除非它们位于其自身的容器中，例如导航VC，那么您将需要上一层。
