Ihar:
I think I understand your motivation -- others have suggested this too
-- and I agree that doing it all from scratch is a great way to learn.
Of course nobody expects to do things this way forever. (Although for
example, does anyone remember WriteNow? Smallest, fastest word
processor ever... because it was almost completely done in assembly.
But the days for that sort of thing are over...)
I learned some useful things just from looking at the code Public Look
posted. And when I was writing my book
(
http://www.oreilly.com/catalog/objectcpr ... probably not the book you
are looking for, however) I learned a great deal from hacking around
the Objective-C runtime. Even though I have no desire to roll my own
method dispatch.
The approach of IB, designing not just objects but all their
interconnections, and then "re-animating" them at runtime, is great,
and will be around for a long time. But just accepting IB is not
learning.
I recall back in the day when I was fascinated by HyperCard (still am)
I posted a question on a CompuServe forum about how its intepreter
worked. I got lectured by none other than Danny Goodman that I didn't
need to know this stuff and I should just let HyperCard make my life
easy. This was quite annoying. But at least my academic interest led me
to grad school to study compilers and interpreters.
So, viva low-level details! :)
Andrew
