This chapter on inheritance builds upon the prior chapter on classes. I am happy that the book is spending a lot of time on this discussion. However, I am still confused. I am reading and re-reading chapter 8. I even went back to chapter 7. I am hopeful that one day I will look back on my struggles and appreciate how hard I worked to figure things out.
This whole inheritance thing is not so simple. Again, it makes me realize that most people cannot just walk into the role of an Objective-C developer. Well, anyway, I was out late and so I was not at my sharpest today. I am very happy with myself as the more confused I am, the more I bear down. I never had the smarts to pick things up instantly. Rather my smarts come from tenacity and good long term memory. In other words, once I [really] get it, I get it. Right now I still don't get it.
In any event, chapter 8 is about creating sub-classes to extend parent classes. It is all very interesting and will be a paradigm shift for my thinking. I have done procedural programming for over 20 years. This is a different animal where I have to understand what I can use from a predecessor and what I can build with downstream classes. Tomorrow I will continue re-reading chapter 8 with no guarantees that I won't go back to chapter 7. I really hope to finish the reading tomorrow in chapter 8.
