It has been awhile since I read about the protocol but now I understand why it is so important. Btw, Hillegass in chapter 25 did not point out it's importance, I had to go online to be reminded. At least for me, the protocol is important as it allows you to relate to multiple objects without having to create all sorts of superclasses to relate things to one another. The protocol lays out the method shells and it is my job in the implementation file to fill in the programming within the methods. The key is that you can have multiple protocols called into one implementation.
I also started reading chapter 26 on Property Lists. Mostly through it but Hillegass is introducing a new Challenge, something he hasn't done in about 5 chapters. I will attack that today.
