Hey there, guys. I have an NSMutableArray with several NSString in it, and I simply want to sort by alphabetical order. I can’t figure out how to do this though… can someone give me an example? I’m guessing the sortUsingSelector: will be the best way to do it, but I don’t understand how I would implement this sort of thing. Thanks for any and all help.


If all you want is alphabetical order, then use the selector compare: or caseInsensitiveCompare: as the selector. This selector is implemented by NSString. How sortUsingSelector: works is, it will pick an object from the array and send the selector to it, with an argument of another object. The selector has to return NSOrderedAscending/Descending/Same. sortUsingSelector: uses this to sort the array. compare: and caseInsensitiveCompare: follow this convention, so they’ll do the trick just fine. – DustinVoss
