  试试这个：

  NSCalendar *cal = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
  [cal setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
  NSDate *date1 = yourDate;
  NSDate *date2 = [NSDate date];//Current Date
  unsigned int unitFlags = NSDayCalendarUnit|NSYearCalendarUnit|NSMonthCalendarUnit|NSHourCalendarUnit|NSMinuteCalendarUnit|NSSecondCalendarUnit;                   
  NSDateComponents *diffComps = [cal components:unitFlags fromDate:date2 toDate:date1 options:0];
  [diffComps month] //gives you month
  [diffComps day] //gives you day
  [diffComps year] // gives you year
  [cal release];
