Good day, needed some help. My Navigation bar can be seen in Story.board but not during runtime.
It was displaying well before I added an Embedded Tab Bar controller to the screen. Now I don't even know how to remove the Embeded Tab Bar controller.
Any help would be appreciated. :-)
(sorry my reputation too low and cannot post picture.)
If you are instantiating the view programmatically, make sure you instantiate the storyboard ID for the NavigationController and not the View Controller itself. That was my issue..
So I had exactly the same problem today and found that that it needs to be within a Navigation Controller in the story board hierarchy.
As well as this I found if you present something modally then this needs to be embed in another Navigation Controller too.
Hope this helps

hi
i am currently working in iphone navigation based application. so my app have 30 screen,after navigating five screen i need a TabbbarController . I add tabbar Controller OverMy viewController ( [self.View addSubView:tab.View];) my application work fine and navigation work perfect but my problem is that after navigating from tabScreen to other myViewController which inside tabbbar controller are not relaods but navigated view controller work fine .
so above my code adding tabbar is wrong then plz help me ,thanks in advance.
I have to say, that I don't fully understand your question, I guess this is due to the language barrier, but maybe you can elaborate your explanation a little more. However, I think that I understood your problem. You want a UITabbarController (respectively it's view) to be a subview of a UINavigationController. Is that correct?
The answer to this question is simple, but, I'm afraid, unsatisfying your you: You can't do that and even if you could, you shouldn't. Please have a look at Apple's excellent ViewController guide. It says:
Thus, a navigation controller can incorporate custom view controllers, and a tab bar controller can incorporate both navigation controllers and custom view controllers. However, a navigation controller should not incorporate a tab bar controller as part of its navigation interface. The resulting interface would be confusing to users because the tab bar would not be consistently visible.
I have an app where the appDelegate has a UITabBarController. Each of the tabs has a navigation controller which I currently use to push a single detail view onto the stack in each tab. I am hoping to replace my navigation controller on each of the tabs with a splitViewController. I use the Interface builder to provide the UINavigationController for each tab. I am having trouble loading a nib for each tab that has a UISplitViewController in it. I am getting an instance of the UITableViewController class displaying on the screen, but I am not getting the UISplitviewController or the Popover or the detail view etc. These classes are all working in a standalone app, but I am not able to get them into each of the tabs in one app. Although I am currently using the Interface Builder I am open to doing this programmatically. If someone has suggestions, or an example small project of a Tab based app with individual split views in the tabs I would appreciate it very much. (As this is my first question I am not sure how much code or other pictures from IB would be helpful for me to post. If you need further detail please let me know and I would gladly amend this post.)
Apple documentation
"The split view controller’s view should always be installed as the root view of your application window. You should never present a split view inside of a navigation or tab bar interface."
Moving on...
Not only shouldn't you -- if you do so, an error is thrown when you run. It's impossible.
I'm developing an iPhone application and I'm trying to do this:
I want an application with tree views. The view shown first, doesn't have a navigation bar. If the user tap on a button, I need to open the second view with a navigation bar and a table view. The user can also add new items to the table view. If the user do so, the application will show the third view where the user can add fields (this view has also a navigation bar).
It may seem simple, but for me it is not. I don't know how to use the UINavigationController and have not found yet a similar example for what I do (paragraph translated by google).
UPDATE
I don't know how where to put UINavigationController.
How can I do that? Can I use a UIViewController to call a UINavigationController?
Thank you.
take a look at the Recipes example (it also uses core data which may confuse things a little) http://developer.apple.com/iphone/library/samplecode/iPhoneCoreDataRecipes/Introduction/Intro.html#//apple_ref/doc/uid/DTS40008913
There is also a simpler starting point here http://developer.apple.com/iphone/library/samplecode/TableViewSuite/Introduction/Intro.html#//apple_ref/doc/uid/DTS40007318 but the Recipe example covers just about everything you need.
EDIT:added the following
For the very simplest example use XCode to build a new application - a navigation based application (sorry, I'm in front of a PC today so that is from memory). That will give you a blank application with the navigation controller created. You then use the navigation controller to push and pop your view controllers
ViewController Programming Guide
I've been playing around with the iPad SDK looking for ways to improve my current iPhone app. I've got a couple place where I think the new "SplitView" would look pretty good. My question is if it's possible to navigate to a "SplitView" with my current navigation based application? Mainly I'm not sure how to push that SplitViewController onto my current stack of views. Any thoughts?
It should always be the root controller according to Apple.
The split view controller’s view
should always be installed as the root
view of your application window. You
should never present a split view
inside of a navigation or tab bar
interface.
You can use a UISplitViewController in a UITabBarController without any problems. I have not attempted to push a UISplitViewController into an UINavigationController however.
(At least) with iOS 8 (which runs on any ipad except the first one) it's possible to use a "present modally"-segue to display a splitviewcontroller.
Drawback is that an existing navigation bar isn't displayed.
Check out the Multiple Detail Views sample app on Apple's Documentation, this could give you a good idea on how to deal with navigation structure and how to display views on the "splitViewController".
Hey everyone, running into a bit of an issue,
I have created all my views through IB, with the main window having a NavigationController, and a TabBarController which loads a TableViewController in its first tab.
The problem happens when i use the searchbarcontroller in the navigation controller, everything works fine with the exception that when the navigation bar at the top disappears, the table expands too high, and i can't figure out what im doing wrong.
Attached is an image of what im referring to, any help would be greatly appreciated.

Some more information:
i have my MainWindow with a UINavigationController, and a UITabBarController. On the first Tab, i have it loading another nib "AVN_TableController" which is a UITableViewController nib, with the Searchbar delegate.
If you've set your view sizes correctly in Interface Builder and are using the "Simulated Interface Elements" to cause the status bar, navigation bar, and tab bar to display, it should work correctly. If not, then what comes to mind is this issue where displaying an action sheet has it's tappable rectangle offset by the height of the tab bar because it is added to the wrong view. Not sure if that would apply here, but it's at least something to consider.
I ended up going the route of creating my own tabbarcontroller, as that was causing the issue.
