4-year iphone shortdate

I'm sure I just missed something. But I searched for this for several days, trying to find how to show a 4-digit year when displaying NSDate with NSDateFormatterShortStyle style. Please let me know if you have a solution. Here is the code I'm using now.

[NSDateFormatter setDefaultFormatterBehavior:NSDateFormatterBehavior10_4];
    NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease ];
    [dateFormatter setDateStyle:NSDateFormatterShortStyle];
    [dateFormatter setTimeStyle:NSDateFormatterNoStyle];

    // add label for birth
    UILabel *birthday = [[UILabel alloc] initWithFrame:CGRectMake(125, 10, 100, 25)];
    birthday.textAlignment = UITextAlignmentRight;
    birthday.tag = kLabelTag;
    birthday.font = [UIFont boldSystemFontOfSize:14];
    birthday.textColor = [UIColor grayColor];
    birthday.text = [dateFormatter stringFromDate:p.Birth];

If you need four-digit years, set dateformat:using the exact format you want. The downside is that you lose the automatic formatting of the locale.

NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setDateFormat:@"MM/dd/yyyy"];

...

birthday.text = [dateFormatter stringFromDate:p.Birth];

If you need localization, you can try changing the format of the short style date.

NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease ];
[dateFormatter setDateStyle:NSDateFormatterShortStyle];
[dateFormatter setTimeStyle:NSDateFormatterNoStyle];

if ([[dateFormatter dateFormat] rangeOfString:@"yyyy"].location == NSNotFound) { 
    NSString *fourDigitYearFormat = [[dateFormatter dateFormat] stringByReplacingOccurrencesOfString:@"yy" withString:@"yyyy"]; 
    [dateFormatter setDateFormat:fourDigitYearFormat];             
}
