The string in this property may contain the special characters
%u as a placeholder for the number of messages with the same thread identifier. If the string in this property is declared in a
.stringsdict property list, the system formats the preview message using the information in that file. For more information about specifying a
.stringsdict property file, see Internationalization and Localization Guide.
