Minor nit:  you shouldn't really have a partly initialized instance  
flying around.

That's the problem right here:


1. RTFDFromRange already returns an NSData, and what you are doing is  
initializing a second NSData object with the pointer of the NSData  
*object*.

2. RTFDFromRange is "an RTFD stream corresponding to the characters and  
attributes within aRange".  This is a pasteboard representation an not  
something you can directly/usefully save as a file.


So, what you need is -RTFDFileWrapperFromRange:documentAttributes: ,  
which returns a file-wrapper object that you can save.

More can be found in the fine documentation:    NSAttributedString  
class reference + some concept docs "RTF Files and Attributed Strings",  
referenced from the NSAttributedString class reference.
