Ios Swift-带TabBar的导航栏工作不正常

就我而言，我正在制作一个实时聊天应用程序。我在主视图中使用大标题和搜索栏。但是，我想将tabBar添加到我的应用程序navigationController，tabBar无法正常工作

注意：我用代码做所有事情，请不要告诉我故事板

下面是应该是什么：

添加选项卡栏时发生了什么：

AppDelegate.swift：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    UIApplication.shared.statusBarStyle = .lightContent

    FirebaseApp.configure()
    window = UIWindow(frame: UIScreen.main.bounds)
    window?.makeKeyAndVisible()

    window?.rootViewController = UINavigationController(rootViewController: TabBarController())

    return true
}

TabBarController.swift：

override func viewDidLoad() {
    super.viewDidLoad()

    let messagesController = UINavigationController(rootViewController: MessagesController())
    messagesController.tabBarItem.title = "Sohbetler"
    messagesController.tabBarItem.image = UIImage(named: "chats")

    viewControllers = [messagesController]
}

您放置了两个导航栏，一个用于tabbar，另一个用于controller隐藏一个导航栏，您的问题将得到解决

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    UIApplication.shared.statusBarStyle = .lightContent

    FirebaseApp.configure()
    window = UIWindow(frame: UIScreen.main.bounds)
    window?.makeKeyAndVisible()
    let objNav = UINavigationController(rootViewController: TabBarController())
    objNav.isNavigationBarHidden = true
    window?.rootViewController = objNav

    return true
}

尝试在viewcontroller中显示选项卡栏的以下行

self.tabBarController?.tabBar.isHidden = false

等待时间限制，我将：）您是否需要TabBarController的导航控制器？您可以删除将解决此问题的UINavigationController。谢谢，但chirag的建议使一切都正确无误
