Keep TabBar when moving to another view controller

Question

I have a storyboard like this

-> NavigationController -> LoginView -> TabBarController -> VC1 -> VC2

I didn't manage to make a "move" from VC1 to VC2 keeping the tab bar.

I tried the followings :

• Segue (Show type)

  self.performSegueWithIdentifier("toVC2segue", sender: self)
  

• instantiate programmaticaly :

  // prepare for future display
  let storyboard = UIStoryboard(name: "Main", bundle: nil)
  let navigationVC = UIApplication.sharedApplication().keyWindow?.rootViewController as! UINavigationController
  
  // prepare next view
  let vc = storyboard.instantiateViewControllerWithIdentifier("VC2id")
  
  self.tabBarController?.navigationController?.pushViewController(vc, animated: true)
  

but both make the tab bar disappearing.

I tried also

self.hidesBottomBarWhenPushed = false

but this didn't change anything.

Do you have another idea ?

PS : I updated my scheme above...

Edit : After reading the answers below, I tried to add another navigation controller :

-> NavigationController -> LoginView -> TabBarController -> NavigationController -> VC1 -> VC2

but I have now 2 navigation bars superposed in VC1 and VC2...

Answer 1

You need to set TabBarContoller as rootViewController of the app. So scheme should be as follow:

TabBarContoller -> Tab1 -> UINavigationController -> ViewContoller1 -> ViewContoller2.

In such case you can navigate between ViewContoller1 and ViewContoller2 and TabBarContoller will remain visible.

Answer 2

Your view hierarchy should not look like this if you want to keep the tabBar.

-> NavigationController -> TabBarController -> VC1 -> VC2

You should change it to -> TabBarController -> NavigationController -> VC1 -> VC2
