I now am the owner of Programming in Objective-C by Shephen G. Kochan. I am learning more about the syntax of Objective-C. I am also becoming more familiar with the key differences between procedural languages such as C and object oriented languages like Objective-C. I am finding it very helpful to hand type the example programs directly from the book. By not using pre-typed source code files I am learning more quickly and completely.
The book is divided into two main parts. The first part is about Objective-C itself in general. The second part is more specifically about the Foundation Framework. Thus far this is proving to be a review of things I learned about C and new things about the Objective-C extensions to ANSI C that are very interesting. I will tell you more as my study progresses.
