Issue #471

let navigationController = UINavigationController(rootViewController: viewControllerA)
navigationController.pushViewController(viewControllerB, animated: true)

In view controller B, need to set hidesBottomBarWhenPushed in init

final class ViewControllerB: UIViewController {
    let mainView = EditPaymentMethodView()
    var scenario: PaymentMethodScenario!

    init() {
        super.init(nibName: nil, bundle: nil)

        hidesBottomBarWhenPushed = true
    }

    required init?(coder: NSCoder) {
        fatalError()
    }
}
