在标签之间切换时，如何创建保留在屏幕上的视图？ [英] How do I create a view that stays onscreen while I switch between tabs?

问题描述

我有一个标签栏控制器有5个不同的项目，每个代表不同的意见。这些视图表示拨号盘，联系人，通话记录等。选择不同的选项卡切换到不同的视图控制器，并显示不同的视图，这是标准的。

I have a tab bar controller with 5 different items, each representing different views. These views represent a dialpad, contacts, call history, etc. Selecting a different tab switches to a different view controller and displays a different view, as is standard.

我想显示一个持久的视图，当在选项卡栏上进行不同的选择时不切换。

However, I'd like to display a persistent view that does not switch when different selections are made on the tab bar. How can I display such a view that remains onscreen at all times?

推荐答案

创建共享视图控制器。并在必要时在窗口上添加视图，并将该视图置于前面。

Crete a shared view controller. And add the view on window whenever its necessary, and bring that view to front.
