我一直在编写没有故事板的swift。通过这样做，我认为将标签栏添加到我的视图控制器会很有趣。我一直在研究尝试这种方法的不同方法，但是，我还没有找到适合我的应用的答案。
//This is my app delegate
window = UIWindow(frame: UIScreen.main.bounds)
window?.makeKeyAndVisible()
let mainController = UINavigationController(rootViewController: mainViewController())
let loginController = UINavigationController(rootViewController: LoginController())
FirebaseApp.configure()
userIsloggedIn = defaults.bool(forKey: "User is Logged In")
if userIsloggedIn == true {
window?.rootViewController = mainController
} else {
window?.rootViewController = loginController
}
UINavigationBar.appearance().barTintColor = GREEN_Theme
return true
}
//这是我的TabBar控制器，放在我的“mainViewController”
上class CustomTabBarController：UITabBarController {
override func viewDidLoad() {
super.viewDidLoad()
self.tabBar.barTintColor = GREEN_Theme
self.tabBar.isTranslucent = true
self.tabBar.tintColor = .white
let mainController = UINavigationController(rootViewController: mainViewController())
mainController.tabBarItem.title = "Find Jobs"
mainController.tabBarItem.image = UIImage(named: "job-search")
let settingsController = UINavigationController(rootViewController: settingsViewController())
settingsController.tabBarItem.title = "Settings"
settingsController.tabBarItem.image = UIImage(named: "settings")
let notificationsController = UINavigationController(rootViewController: notificationsViewController())
notificationsController.tabBarItem.title = "Notifications"
notificationsController.tabBarItem.image = UIImage(named: "notification")
let messagesController = UINavigationController(rootViewController: messagesViewController())
messagesController.tabBarItem.title = "Messages"
messagesController.tabBarItem.image = UIImage(named: "chat")
let historyController = UINavigationController(rootViewController: jobhistoryViewController())
historyController.tabBarItem.title = "Job History"
historyController.tabBarItem.image = UIImage(named: "medical-history")
viewControllers = [historyController, notificationsController, mainController, messagesController, settingsController]
return
}
}
//最后，这是我的mainViewController

我的目标是将customTabBarViewController与我的主View控制器结合使用。如果我运行我的应用程序，它将我设置为customTabBar，它与我的mainVC重叠。如果我退出并尝试登录，我将被置于黑色背景的默认tabBar屏幕。
答案 0 :(得分：0)
目前尚不清楚您的问题是什么。您说由于您的登录，您不希望将UITabBarController添加为rootViewController，但是在您的示例中，您提供的解决方案是根据登录情况调整要设置的视图控制器。（在登录后再次调用该条件。）
但是，要直接回答您的问题，如果您要将UITabBarController添加到UIViewController，则应使用遏制。
// Adding a contained view controller
addChildViewController(tabBarController)
view.addSubview(tabBarController.view)
tabBarController.didMove(toParentViewController: self)
// Removing a contained view controller
tabBarController.willMove(toParentViewController: nil)
tabBarController.view.removeFromSuperview()
tabBarController.removeFromParentViewController()
