## Declaration

```swift
func CFUserNotificationCancel(_ userNotification: CFUserNotification!) -> Int32
```

## Parameters

- `userNotification`: The user notification to cancel.

## Return Value

## Discussion

Discussion You must cancel a user notification if you want to remove its dialog from the screen before the user dismisses it. It is not sufficient to just release the object.
