iOS Navigation Back Button

Question

I’m having a scenario,   I had 3 controllers, lets assume A,B and C. When app launches I’m transitioning from A to C using segue. Later, in C by using a button I’m moving to B using segue again. So, now I’m in B when I click “Back” it is transitioning to C, but it has to move to A.

  How is this possible, any hint/idea?

If you're moving in direction of A -> C -> B, how can you think is possible to go "back" to A from B? O.o You can skip the C controller, but it's not the meaning of "back" — Luca D'Alberti, Jun 03 '16 at 13:18
assign the tag properly on your question in which language you ask — Anbu.Karthik, Jun 03 '16 at 13:19

Put this code in B controller's back button.

for viewcontroller in self.navigationController!.viewControllers as Array {
            if viewcontroller.isKindOfClass(HomeVC) { // change HomeVC to your viewcontroller in which you want to back.  
                self.navigationController?.popToViewController(viewcontroller as! UIViewController, animated: true)
                break
            }
        }

OR If Class A is your RootView controller

self.navigationController?.popToRootViewControllerAnimated(true)

If your Class A viewController is root, you can set this code on back button:

self.navigationController?.popToRootViewControllerAnimated(true)
