    <p>I have a navigation controller as the root view controller. I have a UIView then a UITableView, then again a UITableView, then a TabbarView and each of my tabbarview is a hierarchy of views. Now my problem is that I am able to get the value of self.navigationcontroller till the last UITableView but the value gets null in the TabbarView. Now is there a way I can access the value in the Tabbarview. Do I have to create a new navigation controller for each tabs in the tabbarview and then assign the root navigation controller value to it? </p> <p>My below code does not work, The last controller where I can get the value of the navigationController is AssignmentViewController.</p> <p>Code from AssignmentViewController:</p> <pre><code>- (void)viewDidLoad { UITransTabViewController *transtvController = [[UITransTabViewController alloc] initWithNibName:@"TransTabViewController" bundle:nil]; self.transtabViewController = transtvController; transtvController.naviController=self.navigationController; [transtvController release]; } </code></pre> <p>In my UITranTabViewController.h I have the below code,</p> <pre><code>@interface UITransTabViewController : UIViewController &lt;UITabBarDelegate&gt; { NSArray *viewControllers; IBOutlet UITabBar *tabBar; IBOutlet UITabBarItem *arrivalsTabBarItem; IBOutlet UITabBarItem *departuresTabBarItem; UIViewController *selectedViewController; UINavigationController *naviController; } @property (nonatomic, retain) NSArray *viewControllers; @property (nonatomic, retain) IBOutlet UITabBar *tabBar; @property (nonatomic, retain) IBOutlet UITabBarItem *arrivalsTabBarItem; @property (nonatomic, retain) IBOutlet UITabBarItem *departuresTabBarItem; @property (nonatomic, retain) UIViewController *selectedViewController; @property (nonatomic, retain) IBOutlet UINavigationController *naviController; </code></pre> <p>I am trying to set the value of naviController from the AssignmentViewController, but still I get the </p> <pre><code>NSLog(@"MY NAV CONTROLLER IN TRANSTABVIEWCONTROLLER IS = %@", self.naviController); </code></pre> <p>value as NULL.</p>

    1. COMy answer was wrong as I presumed it was being called from one of the view controllers in the tab bar controller.

    3. COI try to print the value to the Console and it prints it fine, but I get the value as null if I try to print it form the TransTabViewController. So I guess it is not being assigned properly. Can you help me with that?

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.
