Question

I am in a context where From some 3 classes I am navigating to a class say classX, and I have a back button on classX, on click of that back button I need to navigate to the class from which it has been navigated, so I need to check from which viewcontroller its been navigated, is it possible to do with out using UINavigationController ?

Answer 1

You would check whether the type of the presenting view controller is the type you expect via:

if ([self.navigationController.presentingViewController isKindOfClass:[ParentController class]]) {
     ...
}
