Question

    NSCalendar *gregorian = [[NSCalendar alloc]
                         initWithCalendarIdentifier:NSGregorianCalendar];

NSUInteger unitFlags = NSMonthCalendarUnit | NSDayCalendarUnit;

NSDateComponents *components = [gregorian components:unitFlags
                                            fromDate:dateBegin
                                              toDate:dateEnd options:0];
totalDays = [components day];

That not gives me the total days between the 2 dates but simple the difference between the 2 days of the 2 dates. it dateBegin is 8 sep 2012 and dateEnd is 10 nov 2012 the result is 2! Why ?

Answer 1

Change your bellow line

NSUInteger unitFlags = NSMonthCalendarUnit | NSDayCalendarUnit;

to

NSUInteger unitFlags = NSDayCalendarUnit;
