Chapter 4 Delegation Pattern

Guys, thanks for the good book, I reference it regularly for ideas and refresher. I have been using a delegate pattern for UITableviews for several years now so I was surprised that the chapter talked about delegation but then made the ViewController the delegate to conform to UITableViewDataSource and UITableViewDelegate. While correct, I think a good update would be to show the protocols being satisfied by a helper class thus showing the true power of the delegate protocol.

Thanks for considering
