Start with your NSDocument subclass. Instead of overriding
-dataRepresentationOfType: and -loadDataRepresentation:ofType:,
override -fileWrapperRepresentationOfType: and
-loadFileWrapperRepresentation:ofType:.
Example code is always welcome.
I don't have any at hand, but in a nutshell it's pretty easy. Then add
one or more file wrappers - which are NSFileWrapper instances - to an
NSDictionary. Then use that dictionary to create a dictionary wrapper,
which is also an NSFileWrapper instance.
Blah. Never post before coffee. :-(
I meant to write, use that dictionary to create a *directory* wrapper...
Finally, use the directory wrapper's
-writeToFile:atomically:updateFilenames: method to write the whole
mess to disk.
