我是iPhone开发的新手......现在我正在尝试构建一个应用程序,我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
和那些控制器添加标题。
我试过了:
firstView.title = @"First View";
和
tabItemOne.title = @"First View";
但这两个不起作用..我该如何做到这一点?

设置 aViewController.title 为 navigationItem 和 tabBarItem 设置标题。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";

UITabBarItem *item = [[UITabBarItem alloc] initWithTitle:@"First View" image:[UIImage imageNamed:@"First View.png"] tag:0];
[tabItemOne setTabBarItem:item];
[item release];
如果我是对的。

要设置控制器选项卡的标签,请执行以下操作:
tabItemOne.tabBarItem.title = @"First View";
(顺便说一下,你可能想重新考虑一下你的变量名。它们很混乱。tabbar听起来应该是UITabBar的一个实例,当它实际上是一个UITabBarController时。的firstView和secondView声音就像UIView的实例一样它们实际上是UIViewController子类的实例.tabItemOne和tabItemTwo听起来像UITabBarItem的实例,当它们实际上是UINavigationController的实例时。)

UITabBarItem *item= [[[[appDelegate tabBarController]tabBar]items ]objectAtIndex:0];
//item.image=[UIImage imageNamed:@"hometab.png"];
item.title=@"First View";
item= [[[[appDelegate tabBarController]tabBar]items ]objectAtIndex:1];
//item.image=[UIImage imageNamed:@"hometab.png"];
item.title=@"Second View";
