Presenting View Controller within Navigation Controller and TabbarController

Question

Coming from a separate IntroViewController, I'm trying to present a UIViewController that's embedded in a UINavigationController, which is also one of three option in a UITabbarController.

let tabVC = storyboard?.instantiateViewController(withIdentifier: "TabBarViewController")
self.present(UINavigationController(rootViewController: tabVC!), animated: true, completion: nil)

When I present my View Controller with the code above, the Navigation controller isn't complete, missing the bar items from all the View Controllers (see image).

I've been on this for a few hours, and can either only get the TabbarController to show, the UINavigationController, but not both. Thanks for any help. Much appreciated!

UPDATE: I should clarify, the problem only exists when I try to present it from another View Controller. When I use it as an initial View Controller, everything is fine.

Check this maybe it would help. stackoverflow.com/questions/44122404/… — Kegham K.

Use this code to init your viewControllers in tabBar controller class. I use different storyboard for every viewController and tabBarButton but you also can init them from one storyboard just init right view controller in makeTabBarItemForViewController method

private func loadViewControllers(animated: Bool){

    var viewControllers = [UIViewController]()
    viewControllers.append(self.makeTabBarItemForViewController(storyboardIdentifier: "CurrentChannels", title: LocalizationUtil.localizedString(forKey: "On Air"), selectedImageName: Assets.tabBarIconOnAir.rawValue, imageName: Assets.tabBarIconOnAirUnselected.rawValue))
    self.viewControllers = viewControllers;
    self.setViewControllers(viewControllers, animated: animated)
}


private func makeTabBarItemForViewController(storyboardIdentifier: String,title:String , selectedImageName:String , imageName:String)-> UIViewController{
    let storyboard = UIStoryboard(name: storyboardIdentifier, bundle: nil)
    let vc:UIViewController? = storyboard.instantiateInitialViewController();
    let selectedImage = UIImage(named: imageName)?.withRenderingMode(.alwaysOriginal)
    let notSelectedImage = UIImage(named:selectedImageName)?.withRenderingMode(.alwaysOriginal)
    let item = UITabBarItem(title: title, image: selectedImage, selectedImage: notSelectedImage)
    vc!.tabBarItem = item

    if let navVC = vc as? UINavigationController{
        navVC.delegate = self
    }
    return vc!
}
