As you can see from the repeatInterval property, that you can specify only the predefined calendar units.

enum {
   NSEraCalendarUnit = kCFCalendarUnitEra,
   NSYearCalendarUnit = kCFCalendarUnitYear,
   NSMonthCalendarUnit = kCFCalendarUnitMonth,
   NSDayCalendarUnit = kCFCalendarUnitDay,
   NSHourCalendarUnit = kCFCalendarUnitHour,
   NSMinuteCalendarUnit = kCFCalendarUnitMinute,
   NSSecondCalendarUnit = kCFCalendarUnitSecond,
   NSWeekCalendarUnit = kCFCalendarUnitWeek,
   NSWeekdayCalendarUnit = kCFCalendarUnitWeekday,
   NSWeekdayOrdinalCalendarUnit = kCFCalendarUnitWeekdayOrdinal
   NSQuarterCalendarUnit = kCFCalendarUnitQuarter,
};

So, if you want the notification to repeat on any of these above intervals you can use the repeatInterval property with any of these values. But if you want the notification to repeat on intervals some like "Every Two Days" or on some irregular intervals, then you have to create individual notifications for each of those reminders.
