我可以拥有多个UITabBarController吗？ [英] Can I have more than 1 UITabBarController?

问题描述

让我们想象一下这种情况：

Lets imagine the scenario:

UITabBarController
-UITabBar
-选项卡1：查看控制器A
-选项卡2：查看控制器B

UITabBarController - UITabBar - Tab 1: View Controller A - Tab 2: View Controller B

当我单击View Controller AI时，我想推另一个UITabBarController：

When I click on View Controller A I want to push another UITabBarController:

UITabBarController
-UITabBar
-选项卡1：视图控制器1
-选项卡2：视图控制器2
-选项卡3：视图控制器3

UITabBarController -UITabBar - Tab 1: View Controller 1 - Tab 2: View Controller 2 - Tab 3: View Controller 3

这可能吗？要拥有一个UITabBarController将另一个UITabBarController推入视图堆栈？

Is this possible? To have a UITabBarController push another UITabBarController onto the view stack?

推荐答案

您当然可以这样做，但是我会重新考虑您的设计。选择UITabBar项并更改选项卡栏本身与人机界面指南。此外，在您的示例中，如何返回到根视图控制器？

You can certainly do this but I would rethink your design. Selecting a UITabBar item and changing the Tab Bar itself goes against Human Interface Guidelines. Besides, in your example, how do you get back to the root view controller?

也许您应该使用UITableView，当您点击一个单元格时，它会推入一个包含以下内容的视图控制器一个UITabBarController（从技术上讲，这也可能与HIG背道而驰，因为选项卡栏在整个应用程序中应该是相同的，但是我有很多应用程序都采用了它，而且看起来很优雅）。因此，以您的示例为例：

Perhaps you should use a UITableView that when you tap a cell it pushes a view controller containing a UITabBarController (technically this might go against HIG too since a tab bar should be the same throughout an entire app but I've had plenty of apps adopt this and it seems elegant). So using your example:

RootViewController：
作为UINavigationController推送，其中UITableView包含两个单元格：
cell1& cell2

RootViewController: pushed as UINavigationController with a UITableView containing two cells: "cell1" & "cell2"

-在 cell1上轻按可推动包含UITabBar（I）的视图控制器，该视图控制器包含 View Controller A和 View Controller B。

-Tapping on "cell1" pushes a view controller containing UITabBar(I) which contains "View Controller A" and "View Controller B."

-轻按 cell2将推入包含UITabBar（II）的视图控制器，其中包含 View Controller 1， View Controller 2和 View Controller 3。

-Tapping on "cell2" pushes a view controller containing UITabBar(II) which contains "View Controller 1," "View Controller 2," and "View Controller 3."

在每种情况下，您都将获得一个后退按钮，而UITabBar本身不必更改。

In each case, you get a "back" button and the UITabBar itself doesn't have to change.
