在 iOS 7 状态栏上方添加 UIView 横幅 [英] Add UIView banner above status bar iOS 7

问题描述

我正在尝试在收到应用内推送通知时在状态栏上方添加横幅.从我读过的内容来看，似乎在 iOS 7 中动态更改状态栏样式的唯一方法是将 UIViewControllerBasedStatusBarAppearance 设置为 NO.这不仅真的很烦人，必须将我所有不同的视图控制器 prefersStatusBarHidden 更改为 [UIApplication sharedApplication].statusBarHidden，而且它也没有给出我想要的效果寻找.

I'm trying to add a banner above the status bar when receiving an in-app push notification. From what I've been reading, it seems like the only way to dynamically change the status bar style in iOS 7 is to set UIViewControllerBasedStatusBarAppearance to NO. This is not only really annoying to have to change all my different view controllers prefersStatusBarHidden to [UIApplication sharedApplication].statusBarHidden, but it also doesn't give the effect I'm looking for.

当横幅从顶部滑动时，我仍然希望状态栏提供的 20 pts 空间保留，但状态栏内容会消失，直到横幅滑动回来.有没有办法做到这一点或在状态栏上方添加子视图或窗口?

When the banner slides from the top, I still want the 20 pts of space that the status bar provides to stay, but the status bar content to disappear until after the banner slides back up. Is there a way to either do this or add a subview or window above the status bar?

基本上我希望这样做:

推荐答案

创建一个新窗口并将您的横幅视图添加到该窗口.当您需要显示横幅时，您可以设置 yourwindow.hidden = NO; 您可以进一步添加动画来显示和关闭它yourwindow.hidden = YES;.

Create a new window and add your banner view to that window. When you need to show the banner, you can set yourwindow.hidden = NO; You can further add animations to showing it and to dismiss it yourwindow.hidden = YES;.

这里的关键是设置yourwindow.windowLevel = UIWindowLevelStatusBar+1;

这将确保您的横幅视图和 yourwindow 始终显示在状态栏上方.

That will make sure your banner view and the yourwindow always appear above the status bar.

请随时提出有关上述任何问题的问题.
