Dear all,
I have been working with Cocoa for some time to build some
toy projects, and now I need to do something more serious.
For this, I would like to understand more about the tech-
nologies that Apple provides, i.e., about KVC, KVO, and KVB.
Are there any books, links, Wiki's out there that discuss
these technologies in greater detail?
Here is why I ask: I manage to work with these technologies
for most of the time, but at certain points I am not 100%
sure what is going on. (Ask me "does this value that you
are fetching here in this C program lie on the stack or on
the heap?" and I can tell you without doubts. But a
question like "is this controller really needed here or could
you do without it" or "is this feature part of Objective-C
or is it implemented in Objective-C?" or "does this feature
change the isa-pointer of an instance?" might be too much for
me right now.)
So I am NOT asking for some tutorials that tell me how to
connect and bind this and this with that and that. This
helped me a lot to get started but won't help me when I am
faced with a more complicated CoreData bug. Also, most
of the Apple documentation is mostly a reference and not
an indeep-discussion of how you do things and why not
to do them in some other way. (Even worse, you cannot (?)
just look up how the technologies are implemented and
try to understand what is going on...)
Thanks a lot,
Kaspar
