如何显示从选项卡栏列表中选定的选项卡栏
我有一个我想要的登录页面，如果用户已经登录，那么他/她可以查看比向未注册用户显示的更多选项卡。这意味着登录用户可以查看更多选项卡。 有人可以给我一些想法吗？

Can anybody please give me some idea?

创建您的LoginViewController。
如果登录成功，将视图推送到 TabBarController，这是您的根控制器，您可以在这里编写代码。
如果不成功，设置 UIAlerView 让他们知道登录不正确，并提供密码恢复机制。
如果你是从头开始，我建议你先获取 TabBarViewController (rootController) 并准备好一切。然后处理 LoginViewController 并将其推送到 rootController（如果登录成功）。
Create your LoginViewController.
If the login is Successful, push the view to the TabBarController, which is your rootController, and you can code your stuff here.
If it is not successful, set UIAlerView letting them know that Login was incorrect, and provide mechanism for password recovery.
If you are starting from Scratch, I suggest that you get the TabBarViewController (rootController) first and get everything ready. Then work on the LoginViewController and just push it to the rootController (if the login is successful).
您可以首先使用
Set，当您的用户未登录时，仅使用所有用户通用的选项卡，然后当用户登录时，使用 setViewControllers:animated: 您将能够添加新的“私有”选项卡。用
animated:YES添加它们会给你一个很好的动画效果。要自定义选项卡的项目，您可以使用此对象：

You can use
Set at first, when your user is not logged in, only the tabs common for all users, then when the user logs in, with setViewControllers:animated: you will be able to add the new and "private" tabs. Adding them with
