I'm using a TabController which has a Navigation Controller as it's root and all works fine thus far except i would like to show the NavigationBar of the child viewcontrollers within the tab bar but for now just the tabcontroller's Navigation Bar shows.
This is how the tab bar shows now. with It's NavBar
This is the Navbar of the child ViewController I want to show
Embed a UINavigationController for each tab bar item rather than a UIViewController. You can then make the root view controller of each UINavigationController point to the view controller you want to use for that tab.
This allows each tab to have its own navigation bar and navigation stack.
EDIT
Also, if you intend on keeping your current navigation controller as the initial view controller, make sure you hide it's navigation bar by unselecting "Shows Navigation Bar" in interface builder
or by setting it in UITabBarController:
self.navigationController?navigationBar.isHidden = true
or by setting it in UINavigationController:
self.navigationBar.isHidden = true

In a view controller, I have an embedded NavigationController with disabled navigation bar. I want to use the navigation bar at the beginning for the embedded NC. How can I achieve that?
I'm trying to display the navigation bar at the top of the screen, but it's not showing in embed navigation controller.
Here is how it is in the storyboard:
And here it's in the simulator:
As you can see, I created a custom TabBar (following this tutorial) at the bottom of the screen so I can navigate between the different views.
I believe that I'm going to have to load the navbar programatically because the only solution that I found was to set the navigation controller as the initial view controller, but I already set another view as the initial one so I can't do that.
Issue :
When you instantiate a viewController using storyBoard identifier they wont come with free embedded navigation controller, even if you have added a NavigationController to them. As a result you are adding a viewController without navigation bar to your tab bar VC.
Solutions:
Solution1: If you want each child viewControllers to carry their own navigation controller hence their own navigation stack, provide a storyboard identifier to Navigation Controller behind your child viewControllers and instantiate the Navigation controller itself rather than ViewController. And add NavigationController as you tab bar looking VC's child. Because navigation controller loads the embdedded VC by default you will see your child VC with nav bar.
Solution2: All that you care for is only nav bar than add the Navigation Controller behind the VC containing tab bar looking View.
Hope it helps
Have you tried constraining the navigation bar to your view? Otherwise it can move offscreen.
You need to point the tab bar controller segue to the navigation controller of your view - otherwise if you point the segue straight to the view you're just loading the view without any navigation controller attached.
I have a RootViewController which is a TabBarController which have 5 ChildViewControllers. Each child is a NavigationController. Each child will be able present a FullScreenController which have modalTransitionStyle set to OverFullScreen and present by calling showDetailViewController. The FullScreenController need to be able to further navigate which will push another ViewController into the current NavigationController.
The problem I am facing is that the FullScreenController is presented by the TabBarController, and I cant present the original TabBarController again since it is the PresentingViewController of the FullScreenController.
Anyone know how to properly support a ViewController hierarchy with the following requirements
Should support a navigation bar and a tab bar
Should be able to present a FullScreenController which don't have navigation bar and tab bar
The FullScreenController can navigate to another ViewController which have both navigation bar and tab bar
Should support navigate backward
Each tab on the tab bar represent its own navigation stack
You can add full screen view as child controller to Each Tab bar controller and keep the close button from full screen view (close will take them back to tab bar view).
Hope this will help.
First I created a VC with TabBarController like this.
The other tabs and the main controller are at other storyboards.
Then, I added the Navigation Controller from the Editor > Embed In > Navigation Controller.
And the TabBarItem immediately disappears.
How can I change my tab bar icons and names?
In your storyboard you can change the tab icon from the Navigation controller. (Provided you have different navigation controllers for different tabs of your tab bar controller). YOUR NC will look something like this. (NC -> VC)
I checked your attach images. There are no issue with your navigation controller it will work fine with your tab bar.
I instantiate my UITabBarController by calling navigationController.viewControllers = #[[self.storyboard instantiateViewControllerWithIdentifier:#"tabController"]];
My Tab bar controller has a child view that is embedded in a navigation controller. However the bar button (item) is unresponsive when I touch them (the buttons in the navigation bar). I have tried logging the action but it appears as if the button is not firing at all.
The only thing that I have done differently is the way i instantiated the tab bar controller. Am I missing something?
I connected the navigation bar button from the storyboard to an action so it is hooked up successfully. Please note there is also a navigation Controller pointing to the UITabbarController not shown below.
The unwanted behaviour maybe because this flow (navigation controller to tabbar controller) is ill advised in the Apple HIG. More information can be found here: Storyboard with NavigationController and TabController. The solution I found was to hide the navigation bar on the navigation controller that links to the navigation bar (can be done in interface builder), then make it reappear in the new navigation controller that the tab bar links to. Confusing I know, I can help anyone who ever has a similar issue.
Is there any specific reason you are doing this:
navigationController.viewControllers = #[[self.storyboard instantiateViewControllerWithIdentifier:#"tabController"]];
You can simply drag an outlet from the UITableViewController to the UINavigationController using only the Storyboard.
I think you forgot to add the navigationItem. In the storyboard, add a navigation Item to your viewController and move your bar button items to the navigation bar that appears on the top.
