Well, you could use a File Wrapper instead of a flat file if you REALLY
wanted to keep the different files separate. I have never personally used
file wrappers before, so you'd have to do the research yourself with Apple's
cocoa docs. All I know is you have to (in your document class) change the
methods dataRepresentationOfType and loadDataRepresentation to the
following:
- (NSData *)fileWrapperRepresentationOfType:(NSString *)aType;
and
- (BOOL)loadFileWrapperRepresentation:(NSData *)data ofType:(NSString
*)aType
respectively. That way, file wrappers are loaded instead. Beyond that, I
have no clue how to use them, so good luck! Hope I was of some help to you.
