bookMarkNode's coders are below, this object has the one
NSNumber, and two NSStrings....
when i look in the debugger at "allItems", the NSNumber is not
well defined.
Well, your question is not very well defined. :)
You don't say specifically what is going wrong. An exception? Missing
values? You talk about numbers in an array, but your code doesn't put
any numbers in an array (that I can see), and nor do you encode an
array (that I can see). If 'allItems' is supposed to be an array of
BookMarkNode property values, it makes no sense to put the
BookMarkNode itself in there, and IAC you don't show us any code that
uses 'allItems', so it's just being leaked.
Whatever your question is, the answer likely is: don't try to use
'encodeObject:forKey:' to encode NSNumber objects. Use one of the
variants like "encodeInteger:forKey:" or "encodeInt32:forKey:" -- you
need to tell the archiver which *kind* of external representation to
use for the number. (Therefore, in your enumerator loops, you'll have
to test the class of the value object you're encoding.)
