That actually would not have helped, because it's an instance

clear way for a manually constructed instance of NSKeyedUnarchiver
to decode a file previously saved using the convenience method.
But really, I've no problem here to solve. The file is long gone. I
just remember going through the docs at the time and throwing my
hands up in frustration that they didn't mention the "root object
key" used by the convenience method. I tried "Root" as the key and
the plain "decodeObject" method, but neither worked. Thanks to
Patrick I now know the key is "root", which I should have tried, but
ought to be documented.
Ak OK, I understand.
I checked back in my own code which uses this and has always worked OK
- I'm using the convenience method to archive for binary files, and a
manual archiver for XML files, and the same manual dearchiver for both
- so I wondered how this was working. Turns out that *by pure chance*
I happened to choose the key "root". Lucky, that.
You're right, it should be documented.
