Answer 1

You cannot add target to stock BackButton, but you can override a UINavigationBarDelegate method in your CustomNavigationController, like this:

class CustomNavigationController: UINavigationController {

@IBOutlet weak var ibNavigationBar: UINavigationBar!

    override func viewDidLoad() {
        super.viewDidLoad()

        ibNavigationBar.delegate = self
    }

}

extension CustomNavigationController: UINavigationBarDelegate {
    func navigationBar(navigationBar: UINavigationBar, shouldPopItem item: UINavigationItem) -> Bool {
        for viewController in viewControllers {
            if viewController.title == "YourTitledViewController" {
                popToViewController(viewController, animated: true)
            }
        }
        return false
    }
}
