问题
I have a ViewControllerA, and its UI layout is designed in the Interface Builder (storyboard).
ViewControllerA has two concrete subclasses, ViewControllerB1 and ViewControllerB2; they have the same UI with its superclass ViewControllerA, but run with different logic.
How can I create two different concrete classes but they share the same UI with storyboard in which you must indicate the view controller's class?
回答1:
Unfortunately storyboard doesn't support subclassing.
You should create delegate in ViewControllerA for different logic.
