Question

I have a tab bar app that has to display in different languages depending on a user’s preference but I can’t find much info on how to change the tab names at run-time. I need the tabs to show the correct names at startup, not when the tabs are accessed.

Best info I could find was running

self.tabBarController.selectedIndex = 1;
tabBarController.selectedViewController.tabBarItem.title = @"Tab Name";

from the app delegate but this first makes the tab active & then sets the name.

Is there not a better way to set tab names at run-time? Ideally I’d like to set them all in one go.

The 2 responses didn’t work for me, I eventually did it like this:

// Create temp strings to hold tab names
NSString *tab0Name;
NSString *tab1Name;
NSString *tab2Name;
NSString *tab3Name;
NSString *tab4Name;

// Set strings according to language
if ([UIAppDelegate.iStegAppLanguage isEqualToString:@"FR"])
{
    tab0Name = @"Accueil";
    tab1Name = @"Produits";
    tab2Name = @"Caisse";
    tab3Name = @"Branches";
    tab4Name = @"Plus";
}
else if ([UIAppDelegate.iStegAppLanguage isEqualToString:@"IT"])
{
    tab0Name = @"Home";
    tab1Name = @"Prodotti";
    tab2Name = @"Checkout";
    tab3Name = @"Filiali";
    tab4Name = @"More";
}
else if ([UIAppDelegate.iStegAppLanguage isEqualToString:@"EN"])
{
    tab0Name = @"Home";
    tab1Name = @"Products";
    tab2Name = @"Checkout";
    tab3Name = @"Branches";
    tab4Name = @"More";
}
else    // Default to german unless specifically set to another language
{
    tab0Name = @"Home";
    tab1Name = @"Produkte";
    tab2Name = @"Checkout";
    tab3Name = @"Filialen";
    tab4Name = @"Mehr";
}

// Set tab name
self.tabBarController.selectedIndex = 1;
tabBarController.selectedViewController.tabBarItem.title = tab1Name;
self.tabBarController.selectedIndex = 2;
tabBarController.selectedViewController.tabBarItem.title = tab2Name;
self.tabBarController.selectedIndex = 3;
tabBarController.selectedViewController.tabBarItem.title = tab3Name;
self.tabBarController.selectedIndex = 4;
tabBarController.selectedViewController.tabBarItem.title = tab4Name;
self.tabBarController.selectedIndex = 0;
tabBarController.selectedViewController.tabBarItem.title = tab0Name;    // Home last so it's shown first
