【问题描述】：

let tabBarController = UITabBarController()

    let VC1 = ConstDetailViewController()

    VC1.tabBarItem.image = UIImage(named: "Home.Re.png")
    let VC1Navigation = UINavigationController(rootViewController: VC1)

    let VC2 = LeaderboardViewController()

    VC2.tabBarItem.image = UIImage(named: "search3.png")
    let VC2Navigation = UINavigationController(rootViewController: VC2)

    let VC3 = MapViewViewController()
    VC3.tabBarItem.image = UIImage(named: "graphRe.png")
    let VC3Navigation = UINavigationController(rootViewController: VC3)

    let VC4 = UserProfileViewController()
    VC4.tabBarItem.image = UIImage(named: "UserRe.png")
    let VC4Navigation = UINavigationController(rootViewController: VC4)

    let loginVC = ConstituencyViewController()

    let VC5Navigation = UINavigationController(rootViewController: loginVC)

    let controllers = [VC1Navigation, VC2Navigation,VC3Navigation,VC4Navigation]

    tabBarController.viewControllers = controllers


    self.window!.backgroundColor = UIColor.white

    self.window?.rootViewController = VC5Navigation

    self.window!.makeKeyAndVisible()

我已经在我的 appdelegate 中配置了标签栏。但现在我错过了我的标签栏。它在标签栏的位置显示一个空白区域。请帮我解决问题。

【问题讨论】：

您的问题还在吗？你按照stackoverflow.com/questions/41584371/…的步骤操作了吗？
@Amanpreet。我仍然想念我的标签栏。
登录页面是否需要标签栏？
@Amanpreet。不，我不想要登录页面上的标签栏。
那么，您是否遵循了这些步骤？根据您的要求，您不需要在应用程序委托中执行选项卡栏控制器任务。请按照这些步骤操作，如果您有任何问题，请告诉我。

    let tabBarController = UITabBarController()

    let VC1 = UIViewController()

    VC1.tabBarItem.image = UIImage(named: "Home.Re.png")
    let VC1Navigation = UINavigationController(rootViewController: VC1)

    let VC2 = UIViewController()

    VC2.tabBarItem.image = UIImage(named: "search3.png")
    let VC2Navigation = UINavigationController(rootViewController: VC2)

    let VC3 = UIViewController()
    VC3.tabBarItem.image = UIImage(named: "graphRe.png")
    let VC3Navigation = UINavigationController(rootViewController: VC3)

    let VC4 = UIViewController()
    VC4.tabBarItem.image = UIImage(named: "UserRe.png")
    let VC4Navigation = UINavigationController(rootViewController: VC4)

    let loginVC = UIViewController()

    let VC5Navigation = UINavigationController(rootViewController: loginVC)

    let controllers = [VC1Navigation, VC2Navigation,VC3Navigation,VC4Navigation]

    tabBarController.viewControllers = controllers


    self.window!.backgroundColor = UIColor.white

    self.window?.rootViewController = tabBarController //TabBarController

    self.window!.makeKeyAndVisible()

    return true
}
