How to set a priority for a reminder - Objective-C

While creating a reminder, I can set alarm for reminder. But I am not able to find any property or method to set priority using objective-c.

EKReminder *reminder = [EKReminder reminderWithEventStore:self.eventStore];
reminder.title = @"Title";
reminder.calendar = self.calendar;
reminder.dueDateComponents = [self dateComponentsForDefaultDueDate];

EKAlarm *alarm = [EKAlarm alarmWithAbsoluteDate: reminderdate]; 
[reminder addAlarm:alarm];

Solution

EKReminder has a priority property.

   reminder.priority = 1;

It's there, but undocumented, since (it was added in iOS 7, but) the EKReminder Class Reference documentation hasn't been updated since iOS 6.
