Is there a way to have some sort of rich text in a file, and load the file into an NSAttributedString? I looked into loading a .rtf file into an NSAttributed String:

NSString *filePathFooter = [[NSBundle mainBundle] pathForResource:kFooterFileName ofType:@"rtf"];

NSError *error = nil;
NSAttributedString *string = [[NSAttributedString alloc] initWithFileURL:[NSURL URLWithString:filePathFooter]
                                                                 options:nil
                                                      documentAttributes:NULL
                                                                   error:&error];

But this leaves me with:

Error Domain=NSCocoaErrorDomain Code=258 "The operation couldn’t be completed. (Cocoa error 258.)"

Is there a way to do this?
