How to add a number of weeks to an NSDate?

Question

I have in the past used the below function to add on a specific time interval using NSDateComponents to an existing date.

(NSDate *)dateByAddin         


        

Answer 1

I prefer to use dateByAddingUnit. It's more intuitive

return [NSDate[[NSCalendar currentCalendar] dateByAddingUnit:NSCalendarUnitMonth value:3 toDate:toDate options:0];
