Talk:Copy a string

From Rosetta Code

Objective-C Example[edit]

Well I don't know Objective-C, but looking at the examples isn't there an error on this line:

NSString *newMutable = [original mutableCopy];

shoudn't it be this below ?

NSMutableString *newMutable = [original mutableCopy];
Well, it's not wrong -- since NSMutableString is a subclass of NSString -- it just makes it less useful. --164.67.199.150 05:34, 18 November 2009 (UTC)
