The localized message to display in the notification alert.
- iOS 10.0+
- macOS 10.14+
- watchOS 3.0+
Use this property to specify the body of the notification alert. If your app is not authorized to display alert-based notifications, this property is ignored.
The body text should contain the final text that you want to display, and should not contain any placeholder characters. To include a percent symbol (
%) in the message body, use two percent symbols (
%%). The system strips all other printf style escape characters from your string prior to display.
