Dismiss and Pop a view controller

I want to go back two levels on my view controller stack. I have three segues in this order: Show, Show, Present Modally. There is a navigation controller in use. From my 4th view I want to go back to the 2nd view. I have tried using self.presentingViewController?.presentingViewController?.navigationController?.popViewControllerAnimated(false);

and

self.presentingViewController?.presentingViewController?.dismissViewControllerAnimated(false, completion: nil);

The second one works only if the 2nd and 3rd segues as 'Present Modally'. How can I get them to work with a dismiss and a pop?

Just call dismissViewControllerAnimated.It will automatically dismiss all view controllers including presented model viewcontroller.

Objective - C

[self.navigationController dismissViewControllerAnimated:YES completion:nil];

Swift

self.navigationController?.dismissViewControllerAnimated(false, completion: nil);

Try dismissing the presented view controller before popping the other two:

func dismissThenDoublePop() {

    // Get the presenting/previous view
    let previousView = self.presentingViewController as UINavigationController

    // Dismiss the current view controller then pop the others
    // upon completion
    self.dismissViewControllerAnimated(true, completion:  {

        // Get an array of the current view controllers on your nav stack
        let viewControllers: [UIViewController] = previousView.viewControllers as [UIViewController];

        // Then either pop two view controllers, i.e. pop
        // to viewControllers[viewControllers.count - 2], or
        // pop to the second view controller in the nav stack,
        // i.e. viewControllers[1]. (In this case I've used the
        // first option.)
        self.navigationController!.popToViewController(viewControllers[viewControllers.count - 2], animated: true);

    });
}
