如何限制UITabBarController上的选项卡数量？ [英] How to limit the number of tabs on a UITabBarController?

问题描述

我有一个带有UITabBarController的iPhone应用程序。一切正常。该应用程序有更多的选项卡，可以在显示器的纵向宽度上显示，因此我们总共看到5个选项卡（最后一个是更多选项卡）。问题是，我们希望将一些不太有趣的东西放在更多标签背后。我知道如果我只有2个视图控制器，那么我只会看到2个标签，依此类推，直到我超过5个标签。

I have a working iPhone app with a UITabBarController. It all works fine. The app has more tabs than can be shown across the portrait width of the display, so we see 5 tabs in total (the last being the "more" tab). The thing is, we want to relegate some of the "less interesting" things to be behind the "more" tab. I know that if I had just 2 view controllers, then I'd see just 2 tabs, and so on until I exceeded 5 tabs.

我们怎样才能显示4个标签（3加上更多标签），而不是5？

How can we show just 4 tabs (3 plus a "more" tab), instead of 5?

我的猜测是：只有设置属性才能实现这一点（这当然很方便！ ），因为我在文档中找不到任何内容，或者坦率地说，在其他方面建议。

My guess is: this is not possible by just setting an attribute (which would certainly be convenient!), since I cannot find anything in the docs, or here frankly, to suggest otherwise.

没有实现我自己的更多选项卡，并提供标签栏控制器只有4个视图控制器（最后一个是我自己的更多控制器），任何提示，技巧或提示都表示赞赏。谢谢！

Short of implementing my own "more" tab, and supplying the tab bar controller with only 4 view controllers (the last being my own "more" controller), any tips, tricks, or hints are appreciated. Thanks!

推荐答案

只是想把它包起来。最后，我实现了自己的更多控制器，并为UITabBarController提供了4个视图控制器，最后一个是我的更多控制器。

Just wanted to wrap this up. In the end, I implemented my own "More" controller, and supplied the UITabBarController with just 4 view controllers, the last being my More controller.

自定义更多控制器是我创建UITabBarController的主要选项卡和相关控制器时创建的通用UITableViewController子类。然后，我将行标题和相应的UIViewControllers添加到更多视图控制器中的数组。当该标签可见并点击一行时，我只需按下相应的视图控制器。

The custom More controller is little more than a generic UITableViewController sub-class that I create when I create the UITabBarController's main tabs and associated controllers. I then add row titles and corresponding UIViewControllers to an array in the More view controller. When that tab is visible and a row is tapped, I just push the appropriate view controller.

整个效果看起来完全是库存，除了我有4个标签而不是这也不像我想象的那样麻烦。永远是奖金。

The whole effect looks totally "stock", except I have 4 tabs instead of 5. It was less of a hassle than I thought it would be to implement, as well. Always a bonus.

希望这可以帮助有人下线。
