Does anybody know what kind of view controller this app uses? I am trying to implement one somewhat like this but can not get the tab bar to appear at the bottom when I use the table view controller. I also can not get the title of the view to appear at the top where it says home.
I would say this is a tab bar controller. The home tab you show may just have a navigation bar placed on top of it as a sub view or it is embedded into a navigation controller.
My image shows a tab bar controller as the root controller and initial controller and the view from the first tab embedded in a navigation controller.
Hope this helps!
The screen you are looking at is a combination of a UItabBarController a UINavigationController and a UITableViewController.

I don't understand why SignIn and SignUp navigation Bar and the back buttons are not visible even when embedding both of these views in the navigation controllers.
Is there anything else we have to do in code. All top bars are inferred in this case and I haven't touched the visibility of any.
There is no back button because there is nowhere to go back to. Your sign up and sign in view controllers are the root view controllers of their respective navigation controllers.
There is no visible title because what you are looking at is the navigation item of the tab bar controller, which has no title.
Your architecture posits a navigation controller insider a navigation controller, which is illegal:
nav controller -> tab bar controller -> nav controller
You can't do that.
Also you can't put a tab bar controller inside a navigation controller. A navigation interface inside a tabbed interface is fine (as illustrate in Apple's own docs: https://developer.apple.com/documentation/uikit/uinavigationcontroller). The reverse, a tabbed interface inside a navigation interface, is not.
The simplest solution is to eliminate the first navigation controller completely, as there is no need for it (you are not pushing anything onto it beyond its root view controller).
IN SIMPLE TERMS
Logically, your Tabbar should not be embedded in a UINavigation Controller. Instead, delete the NavigationController and make the Tabbar the root Viewcontroller then embed each UIViewcontroller in a separate Navigation controller
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'm working on my first iOS app and I'm realizing just right now that I don't have a navigation controller. Since I'm already pretty far in the app and not completely sure of how I would implement a navigation controller, I was wondering if I would need one in order to implement a search controller, meaning a UITableViewController with like a navigation bar on top.
To implement a Navigation Controller you just need to select the View Controller in storyboard then Click up top Editor -> Embed In -> Navigation Controller. You could also just add a navigation bar to the top of the View Controller you are using.
These are the two options for adding a navigation bar, however, neither is required for adding a search bar.
You do not need to add a navigation controller just to display a navigation bar. Navigation bar can be added to any UIViewController.
You can also add just the search controller in a navigation controller, without affecting your other view controllers. This will add a Navigation bar to the search controller and also allow you to navigate to (Push) other view controllers.
I created master-detail template for the ipad application and now I want to add Tab Bar to either master view or detail view. I can easily add tab bar controller using editor->embed in ->tab bar controller. However when I run application tab bar is not showing.
Tab bar is showing in storyboard but I am also unable to add extra tab bar items. What am I doing wrong thanks?
You should embed the navigation controller (of either the master or detail VC) in a tab bar controller, then delete the connection between the split view controller and that navigation controller. Finally, remake the connection from the split view controller to the tab bar controller. You'll also need to make several code changes, because the template code refers to the detail controller by its hierarchy in the split view controller, which will now be different.
I searched about this case but I couldn't find how to embed tab bar controller inside a navigation controller properly.
To be more specific; I created navigation controller in didFinishLauncinhWithOptions method inside the appdelagete and I am navigating through my view controllers without any problem.
I have a mainViewController with has 3 button and every button is pushing anotherView to navigation controller. In one of the views I am redirected, I want to use a tabbar.
My question is where should I create my tabbar controller in this case and is it allowed to embed tabbar controller inside navigation controller ? If not what should I do because, I really wanna embed my navigation controller from start and have navigation bar thorough out the entire program.
Thanks in Advance.
After struggling some times, I managed to figured out the solution by inserting new view below the tabbar.
This thread really helped me much about the case;
Tab bar controller inside a navigation controller, or sharing a navigation root view
