If you'd like to just handle one owner per archive, it's real easy, use replaceObject:[NSNull null] withObject: then decode the root object.

With multiple replaced things it's more tricky if you'd like some tips, please email.

Andre.

Thanks.

However, it doesn't seem to work for me. Here's what I did for archiving:

NSArchiver *myArchiver = [[[NSArchiver alloc] initForWritingWithMutableData:[NSMutableData data]] autorelease];
[myArchiver replaceObject:self withObject:[NSNull null]];
[myArchiver encodeRootObject:theRootObject];

I then store [myArchiver archiverData]. Here's how I unarchive:

NSUnarchiver *myUnarchiver = [[[NSUnarchiver alloc] initForReadingWithData:theData] autorelease];
[myUnarchiver replaceObject:[NSNull null] withObject:self];
theRootObject = [myUnarchiver decodeObject];

Yet the unarchived object contains pointers to <null> instead of to the object doing the unarchiving.

What's wrong?
