iOS 有一个“细节”：酒吧随时可用
我想随时在我的应用程序顶部查看有关工具栏大小的小视图。该视图仅可用于显示一些文本详细信息。我正在考虑将根视图控制器设置为导航控制器并将提示设置为我想要显示的内容，但这似乎有点hacky。有人对如何做到这一点有其他想法吗？
I would like to have a small view about the size of a toolbar available at the top of my app at anytime. This view would be available only for displaying some textual details. I was thinking of setting the root view controller to be a navigation controller and setting the prompt to be what I want to display, but this seems kind of hacky. Does anyone have any other ideas on how to do this?

我的方法是将
UIView添加到应用程序委托的UIWindow中。例如，您可以转到application:didFinishLaunchingWithOptions:和[self.window addSubview:overlay];，其中overlay是以编程方式创建的UIView或在IB中。The way I do it is to add a
UIViewto theUIWindowof the application delegate. For example, you can go toapplication:didFinishLaunchingWithOptions:and[self.window addSubview:overlay];where overlay is aUIViewcreated programmatically or in IB.
