标签栏项目未显示 [英] Tab bar item not showing

问题描述

    if(!isUserLoggedIn){

        var loginViewController = mainStoryBoard.instantiateViewControllerWithIdentifier("loginView") as! LoginViewController

        window!.rootViewController = loginViewController
        window!.makeKeyAndVisible()

    }else{

        var mainViewController = mainStoryBoard.instantiateViewControllerWithIdentifier("mainView") as! FirstViewController         
        var myDealsViewController  = mainStoryBoard.instantiateViewControllerWithIdentifier("myDealsViewController") as!MyDealsViewController            
        var settingsViewController  = mainStoryBoard.instantiateViewControllerWithIdentifier("settingsView") as! SettingsViewController            
        var centerNav = UINavigationController(rootViewController: mainViewController) as UINavigationController
        var myDealNavController = UINavigationController(rootViewController: myDealsViewController) as UINavigationController            
        let controllers = [centerNav,myDealNavController,settingsViewController]
        tabBarController.viewControllers = controllers

        window!.rootViewController = tabBarController
        window!.makeKeyAndVisible()          
    }

上面的代码正在运行，但应用程序没有显示标签栏项目，即使当我点击中心标签栏项目时它也能工作.

the above code is working but the app is not showing the tab bar item even though it works when I click on the center tab bar item.

推荐答案

将您的代码行替换为:

var myDealNavController = mainStoryBoard.instantiateViewControllerWithIdentifier("myDealNavController") as! UINavigationController

并将myDealNavController"设置为故事板中 UINavigationController 的标识符.

And set "myDealNavController" as identifier to your UINavigationController in storyboard.
