Well, ask Chuck Toporek ;)

do you know C well? If so, just read the ObjC on-line doc, and start playing
with it.

Nope. C++ would not teach you anything worth the effort (but using the '//'
comments ;). Do learn C well, and then go ObjC. Some SmallTalk experience
would not hurt, but it's *NOT* mandatory by far.
p> Can you recommend a good book for "Learning ObjC"?
I was quite satisfied with the old good "Object-Oriented Programming -- an
Evolutionary Approach" by Brad Cox. I don't know whether it is currently
available, though -- it's a quite old thing.
Anyway, in my experience the ObjC is simple enough not to need a special
book. Just learn it with Cocoa.

void addOneFibonacciNumberTo(NSMutableArray *a) {

if (count<2) [a addObject:[NSNumber numberWithInt:1]];
[a addObject:
[NSNumber numberWithInt:
[[a objectAtIndex:count-1] intValue]+[[a objectAtIndex:count-2] intValue]]];
}

for (i=1;i<1000;i+=3) // wahatever...
[a addObject:[NSNumber numberWithInt:i]];
