You can use NSDateFormatter.

1. Convert your current string to NSDate object, so that you can convert it into any format you want.

   NSString *myString          =   @"3-3-2011";
   NSDateFormatter *dateFormatter  =   [[NSDateFormatter alloc]init];
   [dateFormatter setDateFormat:@"d-M-yyy"];
   NSDate *yourDate                =   [dateFormatter dateFromString:myString];
   

2. Now you can convert this NSDate to any format you want.

   [dateFormatter setDateFormat:@"d-MMMM-yyyy"];
   NSString *resultString          =   [dateFormatter stringFromDate:yourDate];
   [dateFormatter release];
   

Apple's documentation on NSDateFormatter is here.

Take a look at NSDateFormatter. In particular, take a look at the dateFromString: and stringFromDate: methods. You'll need to convert your original string to an NSDate, then convert that NSDate to another string.

One tip for using NSDateFormatter: be sure always to set a locale. If you don't manually set a locale, it has a bug regarding 12/24 hour clock settings. The example code on the page I linked to shows how to set a locale.

Use d-M-Y (or M-d-Y, depending on which is the month):

NSString *myString = 3-3-2011;
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc]init];
[dateFormatter setDateFormat:@"d-M-Y"];
NSDate *yourDate = [dateFormatter dateFromString:myString];

And see the Unicode standard referred to in the Apple docs.
