I need to use the same set of code in 4 view controllers. I am writing this code in -(void)viewWillAppear.
Is there any possibility that I can write this code once and use it in all 4 view controllers?
You could make a subclass of
UIViewControllerwith the common code, and then change each of your existingUIViewControllersubclasses to be a subclass of that new class.
