如何在UITabBarController中設置不同選項卡的標題？

Question

我在TabBarApplication中具有以下標簽。 我從主頁導航到此TabBar。

UIViewController *viewController1 = [[ExpenseRecorderViewController alloc] initWithNibName:@"ExpenseRecorderViewController" bundle:nil];

UIViewController *viewController2 = [[TaxCalculatorViewController alloc] initWithNibName:@"TaxCalculatorViewController" bundle:nil];

UIViewController *viewController3 = [[CurrencyConverterViewController alloc] initWithNibName:@"CurrencyConverterViewController" bundle:nil];

UIViewController *viewController4 = [[emiCalculatorViewController alloc] initWithNibName:@"emiCalculatorViewController" bundle:nil];

self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2,viewController3, viewController4, nil];

現在，如果我嘗試通過類似以下方法來設置這四個標簽的標題，

[[tabBarController.tabBar.items objectAtIndex:0] setTitle:@"title A"];
[[tabBarController.tabBar.items objectAtIndex:1] setTitle:@"title B"];
[[tabBarController.tabBar.items objectAtIndex:2] setTitle:@"title C"];

那就行不通了。 我想我需要在頂部設置導航欄的標題。 但是該怎么做呢？

應該這樣做：

appDelegate.newsNavController = [[[UINavigationController alloc] initWithRootViewController:newsViewController] autorelease];
    appDelegate.newsNavController.navigationBar.tintColor = [UIColor blackColor];
    appDelegate.newsNavController.tabBarItem.image = [UIImage imageNamed:@"IdCard.png"];
    appDelegate.newsNavController.tabBarItem.title = NSLocalizedString(@"Title_News", @"");
