                                        self.window!.rootViewController = appdelegate!.initialViewController!
                                        self.window!.makeKeyAndVisible()

                }else {
                    print("touch id not available...")
                }
            }else {
                if UserDefaults.standard.value(forKey: "PlanSelected") as? Int ?? 0 == 90 {
                    self.initialViewController  = Homescreen_iPhoneVC(nibName:"Homescreen_iPhoneVC",bundle:nil)
                }else {
                    self.initialViewController  = Homescreen6_iPhoneVC(nibName:"Homescreen6_iPhoneVC",bundle:nil)
                }
            }
        }
        let navigationcontroller = UINavigationController()
        navigationcontroller.viewControllers = [appdelegate!.initialViewController!]
        navigationcontroller.navigationBar.barTintColor = AppBG1Color
        navigationcontroller.interactivePopGestureRecognizer?.delegate = self as UIGestureRecognizerDelegate
        navigationcontroller.interactivePopGestureRecognizer?.isEnabled = true
        let frame = UIScreen.main.bounds
        window = UIWindow(frame: frame)
        window!.rootViewController = navigationcontroller
        window!.makeKeyAndVisible()
    }else {
        initialViewController = Login_iPhoneVC(nibName: "Login_iPhoneVC", bundle: nil)
        let frame = UIScreen.main.bounds
        window = UIWindow(frame: frame)
        window!.rootViewController = initialViewController
        window!.makeKeyAndVisible()
    }

    UINavigationBar.appearance().tintColor = .white
    let tapGesture = UITapGestureRecognizer(target: self, action: #selector(dismissKeyboard(_:)))
    tapGesture.cancelsTouchesInView = false
    window?.rootViewController?.view.addGestureRecognizer(tapGesture)

    return true
}

这是我的 Appdelegate 代码，在我的其他条件下，我希望在用户已经启用触摸 id 时首先弹出触摸 id 弹出窗口让用户询问触摸主页按钮登录，但它会直接崩溃，我希望用户已经启用触摸 id 然后他每次他再次打开应用程序时都可以通过触摸访问应用程序。如果任何人都可以提供帮助，那将是非常感谢的。
