UIStoryboard更改选项卡栏按钮文本

Question

我正在使用MainStoryBoard编写程序。我有UITabBarController有5个选项卡。在每个uiviewcontroller的viewdidload中，我这样设置。但是，只有我去那个页面才会这样做。所以，我打算在我的AppDelegate中为所有标签做。我该如何以编程方式进行？我可以在UIStoryBoard中设置文本，但我需要以编程方式设置。

self.title = @"Some title";

为此，您应首先获取故事板实例。然后从故事板获取tabbar。在AppDelegate的以下方法中执行此操作。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
  {
        UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:@"Storyboard" bundle:nil];
        UITabBarController *tabBar = [storyBoard instantiateInitialViewController] ;
        NSLog(@"%@",tabBar.viewControllers);
       // You will get list of your viewcontrollers added to tabbar .Get the instances of those view controllers and set title to them here.
       return YES;
  }
