Cannot hide tab bar in child view controller

Question

In my container that the UINavigationController is built into. NavController 2 viewControllers are connected to this. See image below.

Everything works well, except that both childViewControllers get a TabBar, which I cannot hide, no matter what. Here's how it looks on the device. Container background blue This is how I try to hide from childViewControllers

self.tabBarController!.tabBar.hidden = true self.navigationController!.toolbarHidden = true self.navigationController!.tabBarController!.tabBar.hidden = true self.navigationController?.setNavigationBarHidden(true, animated: false) 

and from the containing viewcontroller:

  self.childViewNavigationController.toolbarHidden = true self.childViewNavigationController.setToolbarHidden(true, animated: false) self.childViewNavigationController.tabBarController!.tabBar.hidden = true self.childViewNavigationController.setNavigationBarHidden(true, animated: false) 

The blue area is 49 points, so I think it is reserved for the tab bar.

Answer 1

The problem remained unresolved. Fortunately, the main view manager was supposed to be presented, not clicked, so the childview navigation manager did not inherit anything from the main navigation controller of the viewcontroller, and the area for the tab bar disappeared.
