当推入我的UITabBarController时，视图控制器隐藏的选项卡栏

Question

Note: And I tried to set the hidesBottomBarWhenPushed to false everywhere it was possible...

Here is how I initialize my UITabBarController in my AppDelegate file:

func initTabBarController()
{
    let myVC1 = MapVC()
    let myVC2 = MapVC()
    let myVC3 = MapVC()
    let myVC4 = MapVC()

    let controllers = [myVC1,myVC2,myVC3,myVC4]

    self.myTabBarController = UITabBarController()
    self.myTabBarController.viewControllers = controllers

    myVC1.tabBarItem = UITabBarItem(
        title: "Map",
        image: image1,
        selectedImage: image11)
    myVC2.tabBarItem = UITabBarItem(
        title: "Map",
        image: image2,
        selectedImage: image21)
    myVC3.tabBarItem = UITabBarItem(
        title: "Map",
        image: image3,
        selectedImage: image31)
    myVC4.tabBarItem = UITabBarItem(
        title: "Menu",
        image: image4,
        selectedImage: image41)

    self.tabNavigationController = UINavigationController(rootViewController: self.myTabBarController)

    self.tabNavigationController.navigationBar.translucent = false
}

Now Here is how I set the rootViewController of my main window:

let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
appDelegate.initTabBarController()
        appDelegate.window!.rootViewController =    
appDelegate.tabNavigationController
        appDelegate.window!.makeKeyAndVisible()

And here is finally how I try to push a new view controller inside one of my ViewController (MapVC):

    let v = UIViewController()
    v.view.backgroundColor = UIColor.yellowColor()

    self.tabBarController?.navigationController?.pushViewController(v, animated: true)

When this code is executed, the Yellow view is well displayed, but the bottom tab bar is hidden.

And I'd like to still have my Tab Bar!!!

I tried to set the property hidesBottomBarWhenPushed to false to any object I can, unsuccessfully.

Please help me!!!

Answer 1

It looks like you have embedded your tabBarController in a NavigationController. That is probably why the tabs are hidden when a new ViewController is pushed on the stack. Instead embed each of the tabBarController's ViewControllers inside their own NavigationController.
