# statusBarFrameUserInfoKey

A key whose value indicates the new status bar frame.

```
nonisolated class let statusBarFrameUserInfoKey: String
```

## Discussion

The key’s value is an <doc://com.apple.documentation/documentation/Foundation/NSValue> object that encapsulates a <doc://com.apple.documentation/documentation/CoreFoundation/CGRect> structure expressing the location and size of the new status bar frame. This key is used with [`didChangeStatusBarFrameNotification`](/documentation/UIKit/UIApplication/didChangeStatusBarFrameNotification) and [`willChangeStatusBarFrameNotification`](/documentation/UIKit/UIApplication/willChangeStatusBarFrameNotification) notifications.
