Ios 从viewcontroller转到tabbar'；以编程方式创建视图

嗨，这是我的故事板，我想从第一视图控制器转到LoggedinViewController

UIStoryboard *myStoryBoard =[UIStoryboard storyboardWithName:@"Story_Board_Name" bundle:nil];
 UITabBarController *tabBarController = [myStoryBoard instantiateViewControllerWithIdentifier:@"TABid"];
self.tabBarController.selectedIndex = 0;
 [self.navigationController pushViewController:self.tabBarController animated:YES];

我通常使用

[self performSegueWithIdentifier:@"s1" sender:self];

但是，如果我添加了tab bar控制器，这行代码不起作用，我如何修复它？

从情节提要中为tab bar控制器指定一个标识符，然后执行类似的操作

 UIStoryboard *myStoryBoard =[UIStoryboard storyboardWithName:@"Your_Story_Board_Name" bundle:nil];
 TabViewController *tabBarController = [myStoryBoard instantiateViewControllerWithIdentifier:@"TAB_Identifier"];
 [self presentViewController:tabBarController animated:YES completion:nil];

希望这对您有所帮助

如果您已嵌入导航控制器，则可以使用以下功能

UIStoryboard *myStoryBoard =[UIStoryboard storyboardWithName:@"Story_Board_Name" bundle:nil];
 UITabBarController *tabBarController = [myStoryBoard instantiateViewControllerWithIdentifier:@"TABid"];
self.tabBarController.selectedIndex = 0;
 [self.navigationController pushViewController:self.tabBarController animated:YES];

或者试试这个

UIStoryboard *myStoryBoard =[UIStoryboard storyboardWithName:@"Story_Board_Name" bundle:nil];
 UITabBarController *tabBarController = [myStoryBoard instantiateViewControllerWithIdentifier:@"TABid"];
self.tabBarController.selectedIndex = 0;
[self performSegueWithIdentifier:@"s1" sender:self];

首先将“tabbarid”赋予故事板中的选项卡

UITabBarController *tabBarController1 = [self.storyboard instantiateViewControllerWithIdentifier:@"tabbarid"];
    tabBarController1.selectedIndex = 1;
    [self presentViewController:tabBarController1 animated:YES completion:nil];

如果

LogedViewController

嵌入了

UINavigationController

，该怎么办？在这种情况下，上层代码不起作用。在我使用此代码的场景中，它会将我带到

UITabbarController

，但不能通过按它们转到其他选项卡。看起来冷极了。我的解决方案是什么？谢谢
