I'm assuming you have the book (2nd ed).
---
I'm angry because the editor missed some real editor things - not technical:
- things like parallelism
- thought encapsulation
- backreferencing previous discussions
We can't do anything about that, but I'm hoping that maybe someone on
this list can help with some of the technicalities of this book.
I'm particularly baffled about the mention of setEmployees: under the
heading "adding undo to raiseman". Why is this function here? I think
it's so that the NSArrayController can talk to MyDocument -- but what
calls it? I understand the retain and release etc. -- but when is this
called, by what, is this part of the default behavior of NSArrayController?
--
p. 146 - How does the insert: message equate into the just explained
'insertObject:inEmployeesAtIndex" ?
Anyone able to explain these bits?
Thanks,
Steven
