Tab Bar Item title before appear Storyboard

Question

my app starts with a tab bar controller which have 5 tabs. At start the first one in presented with its name but the other four don't have a name until I click on them. Then the name appears depending which language the user has. How can I set the name of the tabs before the tab bar appears? I am using storyboard. Is there a way to set title at the tab bar programmatically when all the rest is done with storyboard? I tried in the AppDelegate something like [FirstViewController setTitle:NSLocalizedString(@"Titel1", nil)]; But I got an error that there is no class method for selector setTitle. Thanks.

I had the same problem today. I'm using storyboard too. In my case i used the following way.

I've created a new "Objective-C class" with the name "MainTabBarViewController" as a subclass of "UITabBarController".
In my storyboard in "identity inspector" i changed "Custom class" to "MainTabBarViewController".
In the method "viewDidLoad" in "MainTabBarViewController" i added:

[[self.viewControllers objectAtIndex:0] setTitle:NSLocalizedString(@"home", nil)];

[[self.viewControllers objectAtIndex:1] setTitle:NSLocalizedString(@"statistics", nil)];

[[self.viewControllers objectAtIndex:2] setTitle:NSLocalizedString(@"settings", nil)];

[[self.viewControllers objectAtIndex:3] setTitle:NSLocalizedString(@"info", nil)];

I guess it is not the perferct way, but for me it works perfect.

I can't believe it!! I've been looking for this solution for so long. Thank you so much :) – thedp Oct 14 '13 at 00:36
See my solution below, it doesn't require setting titles with indices. – Markus Rautopuro Mar 23 '14 at 17:29
Thank you for the answer. It works for updating the UITabBarItem images too. – Eneko Alonso Jan 18 '16 at 01:17

I had a configuration with two tabs like this:

MainTabBarController : UITabBarController
    +- MessagesNavigationController : UINavigationController
    +- ContactsNavigationController : UINavigationController

In a configuration with Storyboard and ARC I overrode the initWithCoder: selector in the custom classes of my UITabBarController view controllers (in this case ContactsNavigationController) and initialized the tabBarItem.title there like this:

@implementation ContactsNavigationController

...

- (id)initWithCoder:(NSCoder *)decoder
{
    self = [super initWithCoder:decoder];
    if (self) {
        self.tabBarItem.title = NSLocalizedString(@"Contacts", nil);
    }
    return self;
}

When using storyboards the iOS calls (id)initWithCoder: instead of -(id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil when the storyboard view controller is initialized during UITabBarController launch. Also note that viewDidLoad doesn't get called until the view controller tab is selected from the tab bar.

In the app delegate, where you are creating the view controllers, set the title property here (rather than in viewDidLoad), for example:

vc1 = [[VC1 alloc] init];
vc1.title = @"List";

vc2 = [[VC2 alloc] init];
vc2.title = @"Map";

tabBarController.viewControllers = [[NSArray alloc] initWithObjects:vc1, vc2, nil];

I am using storyboard. So I created them in storyboard. Is there another way to do this in storyboard? – halloway4b Apr 10 '12 at 12:43
I don't know as I don't use storyboard. – Andy Sinclair Apr 10 '12 at 13:20

If you take a look at the FirstViewController created by Xcode using the template Tab-Bar application based in the - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil method you can see something like this:

if (self) {  
    //check your language
    self.title = NSLocalizedString(@"First", @"First");
    self.tabBarItem.image = [UIImage imageNamed:@"first"];  
}

So you have to check for your language and then set the title property, this will set the title on the tab bar and in the navigation bar.

I have a Tab Bar View Controller in Storyboard and when it is presented I want all tab bar title to be shown depending which language the user has configured in his iPhone. – halloway4b Apr 10 '12 at 13:46

Try this, in every view u have to use this method

Suppose this is you first view

-(id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

    if (self) {
        self.title = NSLocalizedString(@"homepage", @"homepage");
        [self.tabBarItem setTag:0];
        self.tabBarItem.image = [UIImage imageNamed:@"homepage"];
    }
    return self;
}

In you app delegate class write this code to add UITabBarController

self.tabBarController = [[[UITabBarController alloc] init] autorelease];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2,viewController3,viewController4,viewController5, nil];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];

Add above code in

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {}

i don't know about the story bored but it will defiantly work in other projects — freelancer, Apr 10 '12 at 13:13
