I'm guessing just an oversight.
Also, you can save a line of code with
NSArray *sortedkeys = [[countries allKeys]
sortedArrayUsingSelector:@selector(caseInsensitiveCompare:)];
If you need to do anything more than simple alphabetical sort it gets more
verbose, but for sorting country names this should suffice.
I suspect this is one of those things for which lots of people have their own
category methods on NSArray and/or NSString.
