首先添加一个UIView，甚至是导航栏

问题描述

我希望在任何其他视图之上显示甚至是导航栏，这是一种pop-up视图，如下所示：

I want to display, above any other views, even the navigation bar, a kind of "pop-up" view that looks like this:

• 全屏黑色背景，0.5 alpha，看到另一个 UIViewController 下面。


• a UIView 中间带有一些信息的窗口，（如果你想了解所有内容，则为日历）。

• full screen black background with a 0.5 alpha to see the other UIViewController underneath.
• a UIView window in the middle with some information, (a calendar if you want to know everything).

为此，我创建了一个包含两个 UIViews （背景和窗口）的UIViewController，我正在尝试显示它。我尝试过一个简单的 [mySuperVC addSubview：myPopUpVC.view] ，但我仍然有上面的导航栏。

To do that, I've created a UIViewController that contains the two UIViews (background and window), and I'm trying to display it. I've tried a simple [mySuperVC addSubview:myPopUpVC.view], but I still have the navigation bar above.

我试图将它作为模态呈现，但下面的 UIViewController 消失了，我失去了透明效果。

I've tried to present it as a modal, but the UIViewController underneath disappears, and I lose my transparency effect.

任何想法都这样做，我相信这很简单...

Any idea to do this, I'm sure it's quite simple...

谢谢！

推荐答案

您可以通过将视图直接添加到keyWindow来实现：

You can do that by adding your view directly to the keyWindow:

UIView *myView = /* <- Your custom view */;
UIWindow *currentWindow = [UIApplication sharedApplication].keyWindow;
[currentWindow addSubview:myView];
