使用UITabBarController时覆盖整个屏幕的视图？ [英] Overlay a view over whole screen, when using UITabBarController?

问题描述

我想在UITabBarController设置中在整个屏幕上叠加HUD风格的透明图形。执行此操作的按钮位于第一个选项卡的屏幕（FirstViewController）中，覆盖图也应覆盖选项卡......这可能吗？

I want to overlay a HUD-style transparent graphic over the entire screen in a UITabBarController setup. The button to do this is in the first tab's screen (FirstViewController), and the overlay should also cover the tabs... is this possible?

推荐答案

您可以直接将新视图附加到窗口。

You could attach your new view to your window directly.

[[[UIApplication sharedApplication] keyWindow] addSubview:myNewView];
