How to drag a navigation controller into a tab bar controller within a storyboard? - ios5

With xibs if you wanted to combine a navigation controller and tab bar controller you could just drag n drop the navigation controller into the tab bar controller.
However this is not possible now with storyboards (in Xcode 5). Is there some other way of doing it graphically?
Note I don't want the navigation controller to cause a tab to appear in the tab bar controller as will happen if you ctrl drag from the tab bar controller to the nag controller. I want a navigation bar and tab bar combined in one view.
There's dozens and dozens of tutorials for this out there, but they are all using nibs or old versions of storyboards/xcode, and when I try to do it for Xcode 5 it isn't possible. I was wondering if there's some new trick to get the same behavior as was previously possible.

In a storyboard, you can control-drag or right-click drag from the UITabBarController to the UINavigationController to add it as one of the view controllers for the tab bar.

Interface builder's not showing the navigation controller's navigation bar inside a UITabBarController

I recently switched to Xcode 4 from 3.2 and so far everything's been fine. There's one thing that's driving me nuts for the last hour or so. In my main window xib, I have a Tab Controller with 4 tabs. Three of them are regular UIViewControllers, but one is a UINavigationController. The problem is that with Xcode 4's Interface Builder, I can't see the navigation controller's navigation bar. I just get a window that says "Address List Table View Controller inside of a Contacts Navigation Controller". Why doesn't Xcode show the nav bar? In Xcode 3's IB I could see it, add buttons, change the title, etc. I can't seem to do that here.
If you watch this video, the person drags a UINavigationController into the tab bar and you see the bar just fine.

I set the custom class to my ContactsNavigationController, and the changes I make in the nav controller's xib don't reflect in the tab controller like the regular view controller's xib changes do.
So, I'm a little confused. I'm not new at this, I've been at Xcode programming since Day One, but I'm quite lost as to why the nav bar doesn't show up in the tab controller's view, and why when I set the nav controller to my custom class (even set the nib file), it doesn't work. Everything else does.
i just had this issue on an older project. i changed the size in the properties for the root view controller and this seems to have flushed interface builder, including it showing the navigation bar on views that were linked to nav controllers, but in IB had no nav bar displaying

No top navigation bar in a tab bar controller application

I'm pretty new in iphone programming and have stumbled upon this issue which I guess should be pretty basic stuff.
I am using a tab bar application created from a template in XCode IOS 5.1. It works fine and creates 3 screens in the storyboard (tab bar controller + + 2 descended views) but when I try adding a top bar to these 2 views there is a problem...
I do this by adding the top navigation bar in interface builder from object inspector for the tab bar controller. After ticking this option the top bar shows perfectly in my storyboard for all 3 screens (tabbarcontroller + 2 descended views) but after I run the project the top navigation bar is no longer there.
What am I missing here? Why is there no top bar?
If you want to show a navigation bar on two ViewControllers of your tab bar based application, then you can do as follows:
Delete the viewcontroller1, then drag ViewController into storyboard from library and select it and go to Editor\Embed In\Navigation Controller.
From the UITabBarController, click on tabbar and right click, select relationship and drag it to the navigation controller. (means add the UINavigationController as a tab).
Hope this helps!
follow as Nuzhat Zari to show navigation bar on viewcontrollers of your tabBar based application
self.tabBar.frame =CGRectMake(0,0,self.view.frame.size.width,50);
This will make Tab Bar to appear at the top of controller.

IOS Storyboard when to use navigation controllers?

Hi I'm new IOS and have been using the storyboard feature, I followed this tutorial which resulted in a working app. I'm slightly confused when to use a navigation controller. In the tutorial above, every tab had a navigation controller. Is this necessary?
I'm in the process of creating a new app and it seems to work whether I add a navigation controller or not to each tab (see pic).
I'm just curios what is the correct process?
Thanks.
As your app is using a UITabBarController each tab will display a separate 'branch' of views. If any of these 'branches' needs its views to be wrapped in navigation functionality (or simply display the navigation bar with a title etc) then you would add a 'UINavigationController` as the primary view controller for that tab, in between the tab bar controller and the first view controller you wish to display for that tab.
If you want a tab to simply display a view controller which doesn't need hierarchical navigation or a navigation bar then you wouldn't need to use a UINavigationController and can directly set your view controller as the controller for that tab.

Add a navigation control to a single tab in xcode 4

I am fairly new to programming with objective-c and xcode 4 and I am trying to make a tab bar application and add a navigation control to a specific tab.
I am able to add a navigation controller inside the tab bar controller, by clicking dragging the navigation controller into the tab bar controller of the MainWindow.xib window. However, by doing this and linking the class and nib to the corresponding view controller and view, respectively, this adds a new tab, which I don't want (as I want a specific/already in existence tab to also contain the nav controller).
Thanks.
I'm not sure what you exactly want to do, but as my understanding, you want navigation controller under tabbar item that is already existed in the tabbar controller. It's not good practice to do it in that way. Rather than that, try add navigation controller first and then add ViewController inside of it (which makes your life easier). Usually Navigation Controller is root of ViewController, but not vice verse. Hope this help.

TabBar controller and Navigation Controller - who is the manager?

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.
