    <p><strong>For the impatient:</strong> </p> <p>I want to have a navigationcontroller who's root viewcontroller is a tabbarcontroller, similar to the iPad application. I am using IOS 5 and Storyboards.</p> <p><strong>For the reading inclined:</strong></p> <p>In my storyboard I have 6 tabs in a UITabBarController that is embeded in a UINavigationController, giving it a "More" button after 3 tabs are shown.</p> <p>doing so gives me two navigation bars when more is pressed:</p> <p><img src="https://i.stack.imgur.com/O32x9.png" alt="double nav bar... what does it mean?!"></p> <p>So I subclass TabBarController:</p> <pre><code>//@implentation MyTabController - (void)viewDidLoad { self.moreNavigationController.wantsFullScreenLayout = NO; self.delegate = self; } - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { // hide nav bar if current controller is "More" controller self.navigationController.navigationBarHidden = viewController == self.moreNavigationController; } </code></pre> <p>Great, this gives me:</p> <p><img src="https://i.stack.imgur.com/yTeTs.png" alt="almost there"></p> <p>My guess was that i needed to relayout the views to account for the statusbar, so i try</p> <pre><code>[self.view setNeedsLayout:YES]; </code></pre> <p>but i get an error saying UIView does not contain a selector for setNeedsLayout so... How do I get the moreNavigationController.navigationBar to account for the statusbar?</p> <p><strong>Update</strong>:<br> I have a second related issue with this. When I hit the "Edit" button the edit controller shows modally. Its navigationbar displays <em>underneath</em> the insured controller (after an animation), and does not receive touches.</p>

    1. COSo the TabBarController was pushed into the NavigatorController? If that's the case, that's not recommended, you should set a NavigatorController for every tabBar View controller, and set the TabBarController as the main window root view controller. If that's not the case, I have no idea what's happening :P.

    2. CO@Raspu That would solve most of my problems, but what about the back button? since to do it this way I would present the tab bar modally and even if I added a back button to each navigation controller it would not have the <__| shape.

    3. COSo you want to be able to go back to the screen before showing the tabbar?. A solution is to push in all the navigator controllers the previous view controller followed by the one you want to show (that way all navbars has the backbutton). Alternative you can set the hidesBottomBarWhenPushed = YES to the first view controller, that way it won't show the tabBar.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
