Question

My app is a tab bar application, which one of the tabs is a TableViewController instead of a viewController which works fine (the table displays great) but where and how do I add UINavigationController to it? 🙂

Answer 1

You can do this 2 different ways… in IB or code. If I’m dealing with a TabBar I usually do it in IB. All you have to do there is is drag a NavigationController object where your tableview object currently sits… then just make your tableviewcontroller the first child of your new navigation object.

TabBarController
-(Tab Bar)
-NavigationController
--(Navigation Item)
--TableViewController

or

If you want to do it in code… I would just set it up within your app delegate (usually because a tab bar is at the highest point in your app… meaning it appears right away after loading):

// Create a tabbar controller and an array to contain the view controllers
tabBarController = [[UITabBarController alloc] init];
NSMutableArray *localViewControllersArray = [[NSMutableArray alloc] initWithCapacity:numberOfTabs];

// setup the view controllers
UINavigationController *myNavigationController;
myNavigationController = [[UINavigationController alloc] initWithRootViewController:myTableViewController];

// add to tab bar controller
[localViewControllersArray addObject:myNavigationController];
tabBarController.viewControllers = localViewControllersArray;

// add the tab bar to the window
[window addSubview:tabBarController.view];

You should then release the objects you just created since they will be retained by the TabBarController and Navigation Controller. Hope this helps
