I have a running project with 2 xibs for 2 UIViewControllers (no storyboard). I am looking for the shortest way to add tabs at the bottom of the screen being able to switch between the views via the tabs.
Thanks,
Simon
SHORT ANSWER:
In your MainWindow add a UITabBarController
In your UITabBarController add UITabBarItems for a UINavigationController
For each of those UINavigationControllers set the RootViewController to be the UIViewControllers that you have already
EDIT: More detailed steps, but not necessarily perfect:
Find out which view is loaded when your app is loaded (depending on your XCode, this may well be MainWindow.xib or its RootViewController)
Edit the thing from #1 (if defined in code, edit in code; if designed through XIB, edit through XIB) so that it is pointing to a UITabBarController (ie mainWindow.rootViewController = tabBarController in code)
Foreach view controller you want to add, add a UINavigationController. If you are using XIB, then just drag new navigation controllers to the tab bar. If you are using code, use tabBarController.viewControllers = #[navController1,navController2,navController3,...]
Foreach of the nav controllers you just created, set its rootViewController to be your ViewController you want to add.

I have an iOS app written in Swift with UITabBarController with 5 UIViewControllers. Now, I have a bunch of UIViewControllers that are not part of the UITabBarController. I'd like to be able to show that same tabbar but I have no idea how to do that. Any clue?
More details: This is one of the View Controllers that the tabbar has. I use storyboard references and split my view controllers into separate more manageable storyboards.
So, the big picture:
There's no initial ViewController since I use storyboardId to get to the initial Navigation Controller. From there we have a ViewController embedded in the same Navigation controller. In that ViewController, there are 2 Container views - one of the size of the bottom ViewController that contains the "hamburger" button that toggles the other Container View which has an embedded UITableView in. When a specific cell is selected it should go to Profile ViewController that's not even in the same storyboard. The segue is set to be Push. Either way, doesn't show the UITabBar on the Profile ViewController
how you doing?
I don't know if I understood, but you are trying to show tabbar after going to another screen, right? If the answer is 'yes', try to change your segue to show(e.g. push).
-----Edit-----
You can do with two ways:
Presenting Modally -> using Current Context
Use push(e.g.) with a navigation view controller, you can also hide the navigation bar if you go to Navigation controller -> Attributes inspector -> Navigation Controller -> Uncheck Shows Navigation Bar
Hope now it works!
Best regards
I am trying to modify a newly placed UITabBarItem item from a UIViewController to a UINavigationController in XCode 4.
Here is a screenshot of a new view controller called "Near Me" and existing view controllers.
Notice how the new one is a UIViewController, I need this changed to a UINavigationController.
Something as simple as this was easily done in Xcode 3.2 and now that Apple has introduced Xcode 4 - it is just horribly difficult to re-learn this new IDE.
You shouldn't modify a UIViewController to be a UINavigationController. Even though a UINavigationController is a subclass of UIViewController, its job is to manage other View Controllers, not Views.
In IB you should create a UINavigationController and then set the existing UIViewController as the root controller of the new UINavigationController.
You can change it in the menu on the right hand side. Just change the class. I hope this is what you are asking for.
First you create window based application an in that MainWindow.xib file put tabBar Controller. Then delete that two UIView controller and add navigation controller under tabBar Controller. You can see below in screen shot.
How would I set a UITabBarController with all its individual view controllers as the root view in a split view? IB doesn't seem to let me change the class of the root view controller to anything else…I'm using Xcode 4.
Are you using the split-view based application-option? In that case, it worked for me to just extend : UITabBarController in the RootViewController.h-file. I'm not sure what behaviour you want here, but if you set it up like that, you should get the tabbar with all your views (you have to add them in RootViewController.m ofc) in the "root"-option on the navigation bar.
If you want the DetailView to show the same, you have to add a navigationcontroller to the detailview as well.
As for the "more elegant" solution with IB, I'm afraid I'm not very fond of or very experienced with IB.
You want to add tabbarcontroller to your split view at rootview side and its very simple.
create as many viewcontrollers subclasses with xib for ipad as u want to put in tabbarcontroller.
Then expand your splitview , u have two things navigationcontroller(which in turns contain rootview controller),detailview controller(right side view).
Open your library just drag tabbar controller exectly onto navigationcontroller ,so it will replace all that navigation controller and rootviewcontroller(i assume u dont need that rootview controller or u can create it later).
now expand this tabbar controller u can see viewcontroller 1 - viewcontroller 2 etc.
Now simply select view controller 1 , open attributes and select nib file on [command 1 attribute] and select controller file for that nib file by press[command 4 attribute].
Reapet this for view controller 2 in tabbarcontroller and save close IB.
run program select landscape then u can see its done.
Thanks to dh14-sl and lecou—the solution was a combination of both your answers. I was trying to drag a tab bar controller from the library onto the list of elements but it wasn't working—turns out I had to drag it to the view itself. Then I had to change the parent class of my rootvc and re-setup connections, but now it seems to work! Thanks guys!
I want to have a UIView inside of a NavigationController that has 4 buttons. Clicking on any of these 4 buttons will push a UITabBarController that contains a NavigationController with a respective UIView.
Is this possible? Tweetie seems to do something similar.
On my application, I have a tab bar view controller, then inside of that, I have navigation controllers going to individual views in my interface builder. I believe if you just copy this format, it will work.(-> means connected)
Tab Bar View Controller->4 separate Navigation Controller->ui views
I hope this helps
I have created an UITabView application. Each view selected from the bar is a seperate controller with own nib file. I switch between them succesfully.
In the first view I have two buttons (check out the screenshot). When clicking them I want to switch to another views which are the parts of the current view controller. I use:
[self presentModalViewController:anotherViewController animated:NO];
That switches the view, but hides the UITabBar. How to keep the bar on the screen after the switch?
P.S. Sorry for the blurred image. I am not allowed to share to much info.
Well I think you are misusing the modal view controller. For a problem like this I'll say you should put them in a view controller stack using UINavigationController. Instead of making each tab a UIViewController make it a UINavigationController, then you can push and pop view controllers on it, which still show the tab bar.
See http://developer.apple.com/iphone/library/documentation/UIKit/Reference/UINavigationController_Class/Reference/Reference.html
use: tabBarController.selectedViewController = newViewController
edit: UINavigationController is not needed here.
