How do I calculate the number of days in this year in Objective C

Question

How can i calculate the number of days in a year for any calendar, not just gregorian. I have tried this

NSUInteger *days = [[NSCalendar currentCalendar] range

Answer 1

I don't know if anybody is still interested in this thread, but is another possible solution:

NSCalendar *calendar = [NSCalendar currentCalendar];
NSDate *startOfYear;
NSTimeInterval lengthOfYear;
[calendar rangeOfUnit:NSYearCalendarUnit
            startDate:&startOfYear
             interval:&lengthOfYear
              forDate:[NSDate date]];
NSDate *endOfYear = [startOfYear dateByAddingTimeInterval:lengthOfYear];
NSDateComponents *comp = [calendar components:NSDayCalendarUnit
                                     fromDate:startOfYear
                                       toDate:endOfYear
                                      options:0];
NSUInteger numberOfDaysInThisYear = [comp day];

using only 2 calls to NSCalendar.
