    <p>I have setup a UITabBarController with two tabs, one is a simple UIViewController and the other is a UINavigationController using a second UIViewController as its rootController (this will later be used to setup a UITableView). My question is with regard to naming the tabs (i.e. setting the title of each UITabBarItem)</p> <p>For the first tab (simple UIViewController) I have added the following (see below) to the controllers -init method.</p> <pre><code>// FROM -[MapController init] - (id)init { self = [super init]; if(self) { UITabBarItem *tabBarItem = [self tabBarItem]; [tabBarItem setTitle:@"ONE"]; } return self; } </code></pre> <p>For the other tab I have added (see below) to the second controllers init (rootController).</p> <pre><code>// FROM -[TableController init] - (id)init { self = [super init]; if(self) { UITabBarItem *tabBarItem = [[self navigationController] tabBarItem]; [tabBarItem setTitle:@"TWO"]; } return self; } </code></pre> <p>Am I setting the second tabBarItem title in the right place as currently it is not showing, when I run the application the first tab says "ONE" the second is blank. Also tabBarItem (above) shows nil when I print the value or look via the debugger.</p> <p><strong>EDIT_001: Added full code from AppDelegate</strong></p> <p>I can correctly set the UITabBarItem from within the AppDelegate when I first create the controllers, ready for adding to the UITabBarController. But I really wanted to do this in the individual controller -init methods for neatness.</p> <pre><code>// UITabBarController UITabBarController *tempRoot = [[UITabBarController alloc] init]; [self setRootController:tempRoot]; [tempRoot release]; NSMutableArray *tabBarControllers = [[NSMutableArray alloc] init]; // UIViewController ONE MapController *mapController = [[MapController alloc] init]; [tabBarControllers addObject:mapController]; [mapController release]; // UITableView TWO TableController *rootTableController = [[TableController alloc] init]; UINavigationController *tempNavController = [[UINavigationController alloc] initWithRootViewController:rootTableController]; [rootTableController release]; [tabBarControllers addObject:tempNavController]; [tempNavController release]; [rootController setViewControllers:tabBarControllers]; [tabBarControllers release]; [window addSubview:[rootController view]]; [window makeKeyAndVisible]; </code></pre> <p><strong>EDIT_002: Solution so far, Update UITabBarItems in app delegate e.g.</strong></p> <pre><code>// TABLE CONTROLLER TableController *tableController = [[TableController alloc] init]; UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:tableController]; [tableController release]; [tabBarControllers addObject:navController]; UITabBarItem *tabBarItem_002 = [navController tabBarItem]; [tabBarItem_002 setTitle:@"TWO"]; [tabBarItem_002 setImage:[UIImage imageNamed:@"GT_TWO.png"]]; [navController release]; </code></pre> <p><strong>EDIT_003:</strong> is there a way to set the UITabBarItem in the UINavigationController or is the delegate (as it seems) really the best place to do it.</p>

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.
