Moving from C to Objective-C?

Question

I was wondering what I needed to know in terms of C to move onto Objective-C. I would be uber-grateful if you could let me know what you think is sufficient to move on Objective-C.

Thanks, ~Daniel

Answer 1

If you're looking to learn C before moving on to Objective-C (which, in my opinion, is a great idea), I would recommend to you Steve Kochan's 'Programming in Objective-C 2.0'. Very similar to his 'Programming in C' book, it will contain all the C you're going to need to use Objective-C, and it's a great primer for learning both languages.

If you're not looking to read a book, though, or you already have one, I would assume that after learning pointers, you will have covered most of the important parts of the C language (of course, it will depend on the order of material in the book, but pointers are usually sufficiently advanced to move on). Good luck!

Answer 2

Objective-C is an object oriented add-on to C language (like C++ for example). So anything valid in C is also valid in ObjC. Just grab some Obj-C specification from Apple - and it will do just fine.

Good luck.
