Instance Property


The date by which the reminder should be completed.


@property(nonatomic, copy) NSDateComponents *dueDateComponents;


The use of date components allows the due date and its time zone to be represented in a single property. A nil time zone represents a floating date. Setting a date component without an hour, minute and second component will set the reminder to be an all-day reminder. If this property is set, the calendar must be set to NSGregorianCalendar; otherwise an exception is raised.

This components’s timeZone property is independent of time zone properties on startDateComponents and its super EKCalendarItem object. By default, the due date is set to the system time zone.

Special Considerations

On iOS, Event Kit requires that a start date is set if the due date is set, however this is not a requirement in macOS.
