我可以使用一个视图控制器在选项卡栏控制器中处理多个视图吗

Question

I am making an app with a tab bar which will display three different timers. The three timers are almost identical aside from the time and a few labels. Currently I am using 3 view controllers on my story board for the timers which use the same class, and embedding these into a tab bar view controller. Is there a way I can have one view controller and then programmatically use it three times in the tab bar view controller? Is this even a good path to go down?

Answer 1

A view can only have one parent so you need three separate view instances to populate the three tabs. And since a view controller only has one view, each of the view instances in the three tabs needs its own view controller instance.

You can have one view controller class with three instances of that view controller, but you can't use one view controller instance and its one view instance to populate three tabs.
