Well, generally speaking, swizzling your isa pointer is a dangerous thing

I tend to agree with John on my own right, but if you look at his signature
you'll probably want to give his words some weight.
I found that the greatest difficulty about coming to Cocoa from other OO
languages is that it takes a while to start "thinking" Cocoa; it takes a while
before you grok it. I've now been playing with Cocoa for about a year and
though I feel like I'm finally starting to approach it with the right mindset
to fully utilize Cocoa. I've programmed (for a living) in C++ and Java and
a host of other non-OOP languages, scripts, reporting languages, etc. and
I found Objective-C's syntax very easy to master (though the Smalltalk-influenced
parts of the syntax didn't "feel" right at first). It really didn't take
very long before I started to get comfortable with the NextStep classes. I
still don't know them all, but I'm comfortable enough that armed with the
headers and doc files, I can accomplish most things I need to without pestering
the list =).
That wasn't enough, though, and it didn't really start to sink in till I'd
been playing with it for about six months and had completed a few applications.
Cocoa gives you an incredible amount of flexibility: Use it. Keep playing
with it and you'll soon find yourself thinking outside of the lines that C+
+ or other languages have trained you to think within. Before long, you'll
probably come to realize that the problem you're trying to solve either 1)
doesn't really need to be solved because you're just not doing it in a "Cocoa"
way, or 2) that it can be solved easily by approaching it differently..
Cheers and good luck.
