Again, I don't agree. Objective-C *is* C, so *obviously* you have to know C. It is a superset. But Objective-C with ARC is *not* manual reference counted Objective-C. It supersedes it. That's the whole *point* of ARC. Those are very different things, and they require very different pedagogy.
My iOS 4 book, as even a glance at the table of contents will reveal, *does* say "learn C before Objective-C". But in the iOS 5 revision of my book, my plan is to use ARC throughout. Of course I will *describe* manual reference counting, so that the reader understands the problem and can grasp what to do in situations where ARC needs a hint; but I don't expect the user to *learn* manual reference counting. That would be like learning to flake a stone tool before you're allowed to use a steel axe. I won't *use* manual reference counting in *any* code outside that explanatory chapter, and I will expect the reader to be using ARC throughout. m.
