Dismiss View Controller to Particular View Controller

Question

My View Contollers Login -> Main Menu -> A -> B -> C -> D

How do i dimiss all view controllers and go back to main menu

For Logout from my view controllers I am doing the following which takes back to Login

func logout{

    self.view.window!.rootViewController?.dismissViewControllerAnimated(false, completion: nil)
 }

Now what i am doing is this

class AppDelegate: UIResponder, UIApplicationDelegate {
     var viewControllerStack: [BaseViewController]!
}

override func viewDidLoad() {
    super.viewDidLoad()
    super.appDelegateBase.viewControllerStack.append(self)  
}

func go_To_MainMenu(){
    var countOfNumberOfViewCOntrollers = self.appDelegateBase.viewControllerStack.count 

        switch countOfNumberOfViewCOntrollers{

             self.presentingViewController?.presentingViewController?.dismissViewControllerAnimated(true, completion: nil)
            break;
        case 2:

            self.presentingViewController?.presentingViewController?.presentingViewController?.dismissViewControllerAnimated(true, completion: nil)
            break;
   }
}

Are you using segues? If so, use an [unwind segue](https://stackoverflow.com/questions/12561735/what-are-unwind-segues-for-and-how-do-you-use-them) — Paulw11, Jul 13 '17 at 08:31

If your MainMenu VC always comes AFTER your Login VC, you could simply use the same method:

To MainMenu:

self.view.window!.rootViewController?.presentedViewController?.dismissViewControllerAnimated(true, completion: nil)

Instead of presenting/dismissing you can use UINavigationController to push/pop view controllers. That way you can use UINavigationController's popToViewController(_:animated:) which can pop to any view controller in navigation stack.

You can use Unwind Segue if MainMenu isn't your rootViewController. Look at this article, hope it will help. Unwind Segue with Swift

This works for me

var presentingViewController = PresentingViewController()
self.dismiss(animated: false) {
    presentingViewController.dismiss(animated: false, completion: nil)
}

Use unwind segue instead of using RootViewController. Using unwind you can go back to any ViewController. DismissViewController always send the controller out from NavigationController.
