How to select ViewController?

Question

1. The app starts on ViewContoller
2. I push TutoViewContoller
3. On some action, I pop TutoViewContoller

I would like to call a method of ViewContoller just after popping TutoViewController. How can I do that ?

Answer 1

You can implement viewWillAppear of ViewController. If you really need to distinguish between TutoViewController and other viewcontroller you have many options to call before you pop it: delegate pattern, passing reference of ViewController to TutoViewController etc.
