Answer 1

First declare your tab bar controller in your delegate .h file

@property (strong, nonatomic) UITabBarController *tabBarController; 

then declare your root view controller and add it to navigation controller in .m file

UIViewController *homeViewController = [[[HomeViewController alloc] initWithNibName:@"HomeViewController" bundle:nil] autorelease];
    UINavigationController *navigationcontroller = [[[UINavigationController alloc] initWithRootViewController:homeViewController] autorelease];

then add the array of controllers to tab bar

self.tabBarController = [[[UITabBarController alloc] init] autorelease];
    self.tabBarController.viewControllers = [NSArray arrayWithObjects:navigationcontroller,secondViewController and so on, nil];
