There is no way to do this (without groping inside private data structures.) In practice, all NSStrings are instances of a few CF-implemented string classes that support both mutable and immutable strings. These internal classes implement the API of both NSString and NSMutableString. I think you’ve posted about this stuff before? It really sounds like you’re on a wild goose chase down a rathole, with this archiving project. I suggest you back up a ways and look at the problem from a high level and find a different way to solve it. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
