Re: What Should I learn Before Cocoa?

What I really need is a conversion manual from Dev Studio to Project Builder/Interface Builder.

I understand the MVC philosophy, however, I am still a little slow in the learning how to implement it with PB/IB (Outlets and Actions) rather than a more connected method of development (DevStudio). Then again, it could just be that I have spent so much time in the MFC environment, much of it comes naturally now.. Who knows....

I come from a background of DevStudio, Borland Delphi, and pygtk/libglade.
I haven't had so much trouble with PB/IB per se, but it has taken 10 months
(granted, on my own time) to begin feeling comfortable with Cocoa.

You said it very well: I understand MVC, but am slow in figuring out
how familiar patterns are implemented in Cocoa. Maybe part of the
problem is that Cocoa offers more "recommended" ways of connecting software
entities to each other, and it's hard to figure out when each technique
is appropriate.

For example, years ago I implemented Callback and Observer components
in Python. The interfaces were simple, and the range of uses broad.

Cocoa provides several mechanisms -- the target/action paradigm,
NSNotificationCenter, informal delegate protocols which define "custom
adapters" for some types of notification -- to cover the same situations.
The interfaces for these mechanisms are comparatively "thick"; there's
more stuff to call. So it has been difficult to figure out which
mechanisms to use in which circumstances.

Anyway, to get back (or at least closer) to the thread, I'm _finally_
becoming comfortable enough with Cocoa to find "Cocoa Programming"
(Anguish, Buck, Yacktman) both understandable and interesting.
So after you've read some of the books on Objective-C and something
like "Building Cocoa Applications with Objective-C", you might want
to pick up a copy of "Cocoa Programming".
