使用故事板时，从UITabbarController添加/删除或显示/隐藏选项卡栏项 [英] Add/Remove or Show/Hide tab bar items from UITabbarController when using storyboards

问题描述

我有一个应用程序需要显示来自 UITabBarController 的不同内容，具体取决于用户是否已注册。有没有办法在运行时从 UITabBarController 添加和删除 ViewController ？显示和隐藏也很好。

I have an application that needs to show different content from a UITabBarController based on if the user is registered or not. Is there a way to add and remove ViewControllers from a UITabBarController at run-time? Show and Hide would be fine too.

在故事板之前，您可以调用 setViewController ，但这在使用stoaryboards时似乎不正确。

Prior to storyboards you could call setViewController but that does not seem to be the right way when using stoaryboards.

推荐答案

您可以删除标签栏项目，如下所示：

You can remove a tabbar item as follows:

NSMutableArray *tabbarViewControllers = [NSMutableArray arrayWithArray: [self.tabBarController viewControllers]];
[tabbarViewControllers removeObjectAtIndex: /*Any index*/];
[self.tabBarController setViewControllers: tabbarViewControllers ];
