Question

I would like to work out the difference in months

at the moment I have this code:

dateInterval = [endDate timeIntervalSinceDate:startDate];

But that returns a value in seconds, I would like to see the difference between the dates in months.

How would I do this?

Thanks

Answer 1

NSDateFormatter *inputFormatter = [[NSDateFormatter alloc] init];
[inputFormatter setDateFormat:@"dd/MM/yyyy"];
NSDate *startDate = [inputFormatter dateFromString:@"07/03/2011"];
NSDate *endDate = [inputFormatter dateFromString:@"07/06/2011"];
NSInteger month_delta = [[[NSCalendar currentCalendar] components: NSMonthCalendarUnit fromDate: startDate toDate: endDate options: 0] month];
NSLog(@"---------------------------->>%d", month_delta);
[inputFormatter release]; // <-- in case not using ARC

it will log:
