UITableView didSelectRowAtIndex TabBar and Subview Not working

Question

I'm tearing my hair out over this gotcha and have been for a couple of weeks. XCode 4.2 with build aimed at IOS4, so I'm dealing with .XIB files.

I'm writing an iphone app with two tabs provided via tabBar, 1) my artists, 2) all artists. Each of the tabs has a UITableview that is fancy. There is also a detail view which desplays more information about the work. (There is also a HUD display which is a copy of Matej Bukovinski's MBProgressHUD)

When I call didSelectRowAtIndexPath I can't bring up the detail view to save my life. (It does fire correctly.

I know I've got to be missing something basic but... I just can't find it to save my life.

Thanks in advance.

In AppDelegate.m, you must add UINavigationController to tab bar view controler instead of normal View controller :

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    //Test on navigationController
    //navigationController = [[UINavigationController alloc] initWithRootViewController:MyArtistsViewController];
    // Override point for customization after application launch.
    UIViewController *artistsVC = [[[MyArtistsViewController alloc] initWithNibName:@"MyArtistsViewController" bundle:nil] autorelease]; //remove autorelease if ARC support
    UINavigationController *viewController1 = [[[UINavigationController alloc] initWithRootViewController:artistsVC] autorelease];

    //UIViewController *tvc = [[TicketViewController alloc] initWithNibName:@"TicketViewController" bundle:nil]; 
    //self.navigationController = [[UINavigationController alloc] initWithRootViewController:_tabBarController];


    UIViewController *viewController2 = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil];
    self.tabBarController = [[UITabBarController alloc] init];
    self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2, nil];


    self.window.rootViewController = self.tabBarController;
    [self.window makeKeyAndVisible];
    return YES;
}
