use storyboard with custom UITabbarController - ios

Question

i have been working on this issue for some time now and cannot find a solution to my problem.
i have a tabbar view controller that i have tried to customise with images, i have the custom graphics working however i need to use code to display and init the tabbar's view controllers. i also have a problem with displaying a navigation bar at the top of one of my tabs which i think is connected to how i am initiating the tab view controllers
the storyboard shows that there should be a navigation bar at the top of the medication tab and that the view is connected to the tab bar via a segue
you can see i have tried to use storyboard segues to link my view controllers to the tab bar controller. i have the following code in the MedicationViewController.m

{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
TakenViewController *viewController2 = [[TakenViewController alloc] init];
MedsListViewController *viewController1 = [[MedsListViewController alloc] init];
MedsAlarmViewController *viewController3 = [[MedsAlarmViewController alloc] init];
self.viewControllers = [NSArray arrayWithObjects:viewController1,
viewController2,
viewController3,nil];
UITabBarItem *tab1 = [[UITabBarItem alloc] initWithTitle:#"Medication" image:[UIImage imageNamed:NULL] tag:1];
UITabBarItem *tab2 = [[UITabBarItem alloc] initWithTitle:#"Taken" image:[UIImage imageNamed:NULL] tag:2];
UITabBarItem *tab3 = [[UITabBarItem alloc] initWithTitle:#"Alarms" image:[UIImage imageNamed:NULL] tag:3];
UIImage* sel = [UIImage imageNamed:#"fmtabSel"];
[viewController1 setTabBarItem:tab1];
[viewController2 setTabBarItem:tab2];
[viewController3 setTabBarItem:tab3];
UIImage* tabBarBackground = [UIImage imageNamed:#"fmtab.png"];
UITabBar *tabBar = self.tabBar;
[tabBar setBackgroundImage:tabBarBackground];
[tabBar setSelectionIndicatorImage:sel];
}
return self;
}
- (void)viewDidLoad
{
UITabBar *tabbar = self.tabBar;
NSLog(#"%f %f", tabbar.frame.size.width, tabbar.frame.size.height);//used to find the size of the bar
[super viewDidLoad];
UIImage* tabBarBackground = [UIImage imageNamed:#"fmtab.png"];
UIImage* sel = [UIImage imageNamed:#"fmtabSel"];
UITabBar *tabBar = self.tabBar;
[tabBar setBackgroundImage:tabBarBackground];
[tabBar setSelectionIndicatorImage:sel];
// Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
with this code i get the tab but there is no navigation bar at the top of this tab.
can anybody suggest what i must do to resolve this?
if you require any more information feel free to ask and i will edit it into the bottom of this question.
thanks in advance :)

Answer 1

To have a Navigation bar, you have to put a UINavigationController between the tabbar controller and the first UIViewController.
All can be done in storyboard without needs of writing a line of code.

Answer 2

If you want the navigation bar to be at the top You should fill your tabbar controller with navigation controllers inited with root controllers, not just plain controllers.
Smth like that:
TakenViewController *viewController2 = [[TakenViewController alloc] init];
MedsListViewController *viewController1 = [[MedsListViewController alloc] init];
MedsAlarmViewController *viewController3 = [[MedsAlarmViewController alloc] init];
UINavigationController * nc1 = [[UINavigationController alloc] initWithRootViewController:viewController1];
UINavigationController * nc2 = [[UINavigationController alloc] initWithRootViewController:viewController2];
UINavigationController * nc3 = [[UINavigationController alloc] initWithRootViewController:viewController3];
self.viewControllers = [NSArray arrayWithObjects:nc1,
nc2,
nc3,nil];
