In our current project we had a tab bar controller, and every corresponding view had a tab bar controller. Lately we decided to use another navigation approach and we removed the tab bar controller.
Unfortunately the tab bar items in the views seem to be unremovable in the SB. In the running app they are not visible. We even tried to reconnect them to a tab bar controller, but no avail. Also, they don't show up in the document outline.
Is there anyone who can spread some wisdom how to remove them?
Try making the bottom bar to none in the attribute inspector of viewcontorller

I have a UITabBarController. Originally I had it connected to 4 UINavigationControllers and each tab would function as expected. Each would navigate to the appropriate view and the tab bar would remain visible allowing the user to switch between tabs.
Now I wanted to connect another UINavigationController to the UITabBarController; essentially creating a fifth tab. I connected the UITabBarController to the new UINavigationController using a Relationship Segue successfully creating a fifth tab. However, when the fifth tab is pressed, the view is shown but there is no tab bar, thus preventing the user from navigating to any other screen.
The Bottom Bar setting is set to 'Inferred' just like the other views but it still does not show the tab bar. Why is the tab bar not showing and how can I make it appear?
Note that the UIViewController not displaying the tab bar has connections to it from other View Controllers but I don't see why this would affect the tab bar displaying.
Silly error on my part. The check box to Hide Bottom Bar When Pushed was checked so unchecking this solved the problem.
I have a problem that my iphone project, my storyboard Tab Bar Controller, become different, like the picture.
When i delete the tab bar controller connect and reconnect that become normal, and i save the project, but when i open it, tab bar controller become different, how could i solve the problem, thanks!
The status bar is disappear, when the Tab Bar Controller become fat.
I have a navigation based app, in one of the screen I now want to add a tab bar. Can any one please share code snippet on how I can do that. Thanks
the common way is to add a navigation view to one within a tab view, not vice versa. as far as i know it is not possible to add a tab bar to a navigation view.
You could call a modal view that uses an underlying tab bar. Another idea is to use the tab bar for the whole app and hide the bar for the views where you don't want it to show up.
I would like to have a view (Hierarchy structure) under Navigation Controller (the top blue navigation bar) that has a TabBar (the black one in the bottom part) to show additional views (each for tab) at the same level.
If you select one of theese views (black tab bar) you should always have the TabBar visible to jump to another view of the same level. In case you want to go back to the upper hyerarchical level you have to select the "back" navigation button in the top bar (blue one) and the "tab bar" should disappear.
Why Apple suggests (it seems to me) to avoid that ?
I'm quoting from "View Controller Programming Guide for iPhone OS" page 39 where is written:
It’s very common to combine tab bar and navigation controllers, as illustrated in Figure 4. To do this, you simply add navigation controllers to a tab bar controller (however, you should never add a tab bar controller to a navigation controller).
Instead I would add a "Tab Bar" under a "Navigation bar" (the manager)
Do I think wrong ?
Thanks for your help !

What they mean is that a tab bar should never be the child of a navigation view. The tab bar is really meant to define different "modes" of your application, while navigation controller's are to show hierarchal data.
If you want some kind of mode within a navigation controller, I think a toolbar tends to be used. For example the toolbar at the bottom in the Mail app.
UIToolbar Docs
The following is correct according to what I have managed to dig on severals forums and documentations:
Tab Bar Controller > Navigation Controller > View
You do a lot just with the interface builder and then bind the TabBarItems, NavigationItems and Controllers to outlets in your code.
Some doc samples:
Building an iPhone App Combining Tab Bar, Navigation and Tab (YouTube)
iphonedevsdk (Forum)
Add NavigationController to TabBarController (Forum Tutorial)
Good luck, you can't do much if you stick to documentation. Visit forums and look for videos.
What they mean is that navigation controller should never get pushed a tab bar view controller because it cannot support it, however a tabbarviewcontroller can support a navigation view controller so you can do it like that. You can also just add a tab bar to your navigation view controllers view (not the navigation stack) and have the navigation view manage the tab bar instead of the UITabBarViewController.
I am trying to make a program with three subviews after the title screen. Two of the views are just standard nib files with UIViewController subclassed to control them, and the third is a Tab Bar view. I can't seem to get the tab bar items to display though. I walked through the Tab bar chapter in "Beginning iPhone Development" which adds the Tab Bar Controller right off the bat as a subview of Window in the app delegate and that works fine. What I want to do though is load up my rootView controller after the third section was chosen from the title screen and then add a Tab Bar view to that. Every time I do this though I get a blank Tab Bar with no tab bar items.
Any help you can provide would be greatly appreciated seeing as I've been working at this for a few days now.
Thanks
You can't push a tab bar controller to a navigation controller, which I assume is what you're trying to do. However, you can use a plain UITabBar and implement your own view switching in a UIViewController subclass (rather than a UITabBarController). See this related question.
