Today I finished up the Object-Oriented Programming with Objective-C white paper from the Apple Developer site. It was a nice high level discussion of Objective-C. There were a few new concepts but it was mostly for reinforcement of what I already learned. There was not an ounce of code to be had.
After that I started another Objective-C book, the Apple Developer's The Objective-C Programming Language. I remember when I started back in May I asked myself if I should start out with this guide prior to reading the Kochan books. Good thing I didn't. It assumes I know C, which by now, I should have at least a fundamental understanding. My understanding is still suspect. When the book described the id I kind of blanked out and did not really get it. I will revisit it tomorrow. Regardless of all this, I have seen so much discussion regarding dynamic typing and polymorphism that it is coming out of my ears. I think I get it by now.
Tomorrow I will continue with this book. I am hoping it will answer a lot of the questions I still have. Otherwise, I may do a week or two with Kochan again.
