I have this code that simple returns Today's date as a string formatted:

+(NSString*) getTodayString_YYYY_MM_DD {

  NSDate    * today = [NSDate date];

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

  return [[formatter stringFromDate:today] autorelease];

}

With instruments I'm not getting a memory leak, but when I Analyze, XCode says:

Object sent -autorelease too many times

If I understand correctly, I have to release manually the formatter as I'm creating it using 'alloc', but I can't release here because I have to return the value, so I add the autorelease.

How I can do it better to improve it ?

thanks,
