以编程方式设置UITabBar标题

我按照下面的方式添加了tabbar： –

FirstViewController *obj_FirstViewController = [[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil]; SecondViewController *obj_SecondViewController = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil]; ThirdViewController *obj_ThirdViewController = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil]; navigation1 = [[UINavigationController alloc] initWithRootViewController:obj_FirstViewController]; navigation2 = [[UINavigationController alloc] initWithRootViewController:obj_SecondViewController]; navigation3 = [[UINavigationController alloc] initWithRootViewController:obj_ThirdViewController]; MainTabBar = [[UITabBarController alloc] init]; MainTabBar.delegate=self; [MainTabBar setViewControllers:[NSArray arrayWithObjects:navigation1,navigation2,navigation3,nil]]; MainTabBar.view.frame=self.view.frame; MainTabBar.selectedIndex=0; [self.view addSubview:MainTabBar.view] 

通过在(void)viewDidLoad写这个，我在viewcontroller中得到了3个选项卡。 但问题是我想将标签的名称设置为1）首页2）collections夹3）关于我们

我试过写下面的代码：

 - 1)obj_FirstViewController.tabBarItem.title=@"Home"; 2)self.title = @"My View Controller"; 

但这不起作用。 任何人都可以帮我如何编程这样做。 在哪里写行，以便在我的tabbar中获得这3个名字

Answer 1

试试这种方式……

 NSMutableArray *controllers = [[NSMutableArray alloc] init]; FirstViewController *obj_FirstViewController = [[FirstViewController alloc] init]; [obj_FirstViewController setTitle:@"first"]; UITabBarItem *item = [[[UITabBarItem alloc] setTabBarItem: [[[UITabBarItem alloc] initWithTitle: @"First") image:[UIImage imageNamed:@"first.png"] tag:2] autorelease]]; [obj_FirstViewController setTabBarItem:item]; [controllers addObject:obj_FirstViewController]; [obj_FirstViewController release]; 

Answer 2

请试试这个

 FirstViewController *obj_FirstViewController = [[FirstViewController alloc]initWithNibName:@"FirstViewController" bundle:nil]; SecondViewController *obj_SecondViewController = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil]; ThirdViewController *obj_ThirdViewController = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil]; navigation1 = [[UINavigationController alloc] initWithRootViewController:obj_FirstViewController]; navigation2 = [[UINavigationController alloc] initWithRootViewController:obj_SecondViewController]; navigation3 = [[UINavigationController alloc] initWithRootViewController:obj_ThirdViewController]; navigation1.title=@"Home"; navigation2.title=@"Second"; MainTabBar = [[UITabBarController alloc] init]; MainTabBar.delegate=self; [MainTabBar setViewControllers:[NSArray arrayWithObjects:navigation1,navigation2,navigation3,nil]]; MainTabBar.view.frame=self.view.frame; MainTabBar.selectedIndex=0; [self.view addSubview:MainTabBar.view]
