我UINavigation在委托类中使用控制器。在第三个视图类上导航两个视图类后，我需要一个tabbar控制器，它可以控制另外三个ViewControllers，并且在前两个视图控制器上不应该看到标签栏。我怎样才能做到这一点 ？

- (void)viewDidLoad
{

    [super viewDidLoad];

    self.title =@"Scan";

    tabController =[[UITabBarController alloc]init];

    ScanTicketView *scan =[[ScanTicketView alloc]initWithNibName:@"ScanTicketView" bundle:nil];

    SearchView *search =[[SearchView alloc]initWithNibName:@"SearchView" bundle:nil];

    HistoryView *history =[[HistoryView alloc]initWithNibName:@"HistoryView" bundle:nil];

   tabController.viewControllers=[NSArray arrayWithObjects:scan,search,history, nil];

    [self presentModalViewController:tabController animated:YES];

}

是的你可以。请参阅此链接的示例

在您想要推送给您的第三个视图（选项卡控制器）的第二个视图控制器中执行此操作

UITabBarController *tabBarController=[[UITabBarController alloc]init];
tabBarController.viewControllers=[NSArray arrayWithObjects:firstViewController,secondViewController,thirdViewController, nil];
//[self.navigationController pushViewController:tabBarController animated:YES];// this works too but since it seems to be against Apple's Human interface Guidelines you can present the view instead of pushing
[self presentModalViewController:tabBarController animated:NO];

理想情况下，TabBarcontroller 应该是应用程序的起始案例。但在极少数情况下，您希望在视图控制器中显示它，请遵循 .. 

 UITabBarController *tabBarController=[[UITabBarController alloc]init];
    tabBarController.viewControllers=[NSArray arrayWithObjects:firstViewController,secondViewController,thirdViewController, nil];

    [self presentModalViewController:tabBarController animated:NO];
