I do appreciate mmalc's suggestion to start from the beginning and
develop an in depth background knowledge of cocoa, etc. I also
understand that not doing this will cause me to struggle, such as
I am with my "wish list". That said, as I said above, its not
really what I'm interested in. I guess you could say I want to
develop a functional knowledge of writing these programs, not an
academic one. But I'm sure, if this were a topic which I have a
more academic interest, I would have given the same advice that
mmalc gave me, so thank you for the advice.
It's not quite clear why regard the advice as "academic", it's
extremely *practical* and based on years of watching people
struggling with Cocoa because they haven't yet learned the basics.
What you're saying is akin to, "I just want to translate The Iliad,
so I don't really need to learn about declensions, conjugations,
tenses, or voices first".
Or in terms of differential equations, which you claim to be familiar
with, it's like someone insisting on learning the Laplace transform
before they've mastered addition, claiming that they don't really
need to understand how to add two numbers to do Laplace transforms.
I'm sure you can see both (a) how someone could argue this (since the
Laplace transform is an algebraic rather than arithmetic operation),
and (b) that they are mistaken.
There's nothing wrong with jumping in feet first for a toy
application, but:
1. Few people get good results first time using the feet-first
approach, so it's normally only appropriate for toy apps (and even
then you might find that, after doing it once, you want to re-
implement it with your new found knowledge).
2. It can be very confusing, particularly if you don't have
sufficient grounding in the basics first. Since the basics of ObjC
and Cocoa are very simple, it really is worth familiarising yourself
with them first.
Kind regards,
Alastair.
