iphone - 将标题添加到以编程方式创建的选项卡栏

Question

我是 iPhone 开发新手...现在我正在尝试构建一个应用程序，在其中以编程方式创建 UITabbarController ，如下所示:

UITabBarController *tabbar = [[UITabBarController alloc] init];
firstViewController  *firstView = [[firstViewController alloc] initWithNibName:@"firstViewController" bundle:nil];

UINavigationController *tabItemOne = [[[UINavigationController alloc] initWithRootViewController: firstView] autorelease];
secondViewController *secondView = [[secondViewController alloc] initWithNibName:@"secondViewController" bundle:nil];

UINavigationController *tabItemTwo = [[[UINavigationController alloc] initWithRootViewController: settings] autorelease];
tabbar.viewControllers = [NSArray arrayWithObjects:tabItemOne, tabItemTwo,nil]; 
tabbar.view.frame = CGRectMake(0,0,320,460);

[self.view insertSubview:tabbar.view belowSubview: firstView.view];
[self presentModalViewController:tabbar animated:NO];

在此，我如何向 tabbar 和这些 Controller 添加标题。 我尝试过:

firstView.title = @"First View";

和

tabItemOne.title = @"First View";

但这两个不起作用..我该如何完成这个？

Answer 1

设置aViewController.title可以设置navigationItem和tabBarItem的标题。如果您希望navigationItem和tabBarItem具有不同的标题，请执行此操作，

// First set the view controller's title
aViewController.title = @"First View Tab";

// Then set navigationItem's title
aViewController.navigationItem.title = @"First View";
