Question

My app is based on a tab bar architecture. In order to have an easy internationalisation mechanic, I do not write any string in XIB files. viewdidload permits to change programmaticaly the strings in the views.

When my app launches, I can see the 4 tabs. But in fact only the first one loads its view controller. The others wait for user click to be loaded.
Tabs title can be changed using [self setTitle:@”Mouhahaha”]; in viewDidLoad of loaded view controller.

If I want to keep my internationalisation mechanic available, I do not set in my XIB the name of tabbar items. But, as at start all tab’ view controllers are not loaded, I have blank titles for some tabs. The right title is set only when the user click on the tab.

I am looking for a way to set this title programaticaly for each tabbaritem. Do you have hints ?

Thanks a lot.

All you need to do is make an instance of UITabBarController, then alloc any views you want in it, then set the UITabBarController views. Make sure that your TabBarController is the one that is visible. Also make sure that any viewControllers you want in your tab bar are being imported with #import.

UITabBarController *c = [self tabBarController];
SecondViewController *s = [[SecondViewController alloc] init];
[s setTitle:@"Whatever"];
c.viewControllers = [NSArray arrayWithObjects:self, s, nil];
[s release];

Put this in the viewDidLoad method of the first controller allocated.

Alternatively you could just change the way your ApplicationDelegate sets up the TabBarController, but i won’t go into that.

Hope this helps
