   -(NSInteger) ComputeYearMonth

  NSDateFormatter *format = [[NSDateFormatter alloc] init];
[format setDateFormat:@"yyyy-MM-dd"];

NSDate *DateOfBirth=[format dateFromString:[NSString stringWithFormat:@"%@-%@-%@",year,month,day]];
NSDate *currentTime = [NSDate date];

NSLog(@"DateOfBirth======%@",DateOfBirth);

NSInteger years = [[[NSCalendar currentCalendar] components:NSYearCalendarUnit
                                                   fromDate:DateOfBirth
                                                     toDate:currentTime options:0]year];

NSInteger months = [[[NSCalendar currentCalendar] components:NSMonthCalendarUnit
                                                    fromDate:DateOfBirth
                                                      toDate:currentTime options:0]month];
NSLog(@"Number of years: %d",years);
NSLog(@"Number of Months: %d,",months);



    return years;
