TabBar application with NavigationBar - ios

Question

I'm building an App which is TabBar based. One of the tabs will display a TableView and I would like to have a NavigationBar at the top.
However I need to localize everything in this app to several languages so it needs to be done in code.
I have the tab bar set up in the AppDelegate;
#implementation AppDelegate
#synthesize window = _window;
#synthesize tabBarController = _tabBarController;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
UIViewController *viewController1 = [[HomeViewController alloc] initWithNibName:#"HomeView" bundle:nil];
UIViewController *viewController2 = [[RecycleViewController alloc] initWithNibName:#"RecycleView" bundle:nil];
UIViewController *viewController3 = [[SettingsViewController alloc] initWithNibName:#"SettingsView" bundle:nil];
UIViewController *viewController4 = [[SettingsViewController alloc] initWithNibName:#"SettingsView" bundle:nil];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2,viewController3, viewController4, nil];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
Each of the windows has the code for the information on the tab.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.title = NSLocalizedString(#"Home", #"Home");
self.tabBarItem.image = [UIImage imageNamed:#"home"];
}
return self;
}
So far so good, but the RecyclingView (TableView) need a navigation bar where I can set the title using NSLocalizedString.
I would be really grateful for some help.

Answer 1

you need to add a UINavigationController at the second index of your tabBarController's viewControllers instead of adding a view controller -
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
UIViewController *viewController1 = [[HomeViewController alloc] initWithNibName:#"HomeView" bundle:nil];
UIViewController *viewController2 = [[RecycleViewController alloc] initWithNibName:#"RecycleView" bundle:nil];
UIViewController *viewController3 = [[SettingsViewController alloc] initWithNibName:#"SettingsView" bundle:nil];
UIViewController *viewController4 = [[SettingsViewController alloc] initWithNibName:#"SettingsView" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController2];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, navController,viewController3, viewController4, nil];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
to set the title at navigation bar you can write this in your RecycleViewController's viewDidLoad
[self.navigationItem setTitle:#"title"];

Answer 2

You can localize the xibs with Interface Builder so you shouldn't have to do it programatically.

Answer 3

The answer for xcode 4.3.2 is:
alloc the UINavigationBar in RecycleViewController.m as this:
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:self];
self.view addSubview:navController.view;
But there is a bug, that navigation bar will display a blank at the top, about 10pixels.
So here is another solution:
use xib builder, add a navigation bar from libary in the top of view RecycleViewController.xib, press ctrl+"navigation Item", point to RecycleViewController.h to insert an IBOutlet,then you will have a good looking navigation bar to show.
