By I got some great feedback on my first screencast - thank you! A few of you asked: how can you show a different view for each of the rows in the table view, instead of just showing the same view for each row?
I can think of a couple of ways to do this. One is to create different view for each row by creating a separate class for each type of view you want to display, and then select the specific view to display in tableview:didSelectRowAtIndexPath: in the BooksTableViewController depending on which row is selected.
As another option, I decided to use the same view, the BookDetailView, but customize the view with a different image for each book. To do this, I created a new model class, BooksModel, and stored the titles of the books, and images for each book in this class. Then, based on the row selected, I set the appropriate image in the view (from tableview:didSelectRowAtIndexPath: when the view controller for the detail view is created) before displaying the view.
Here's a new screencast that expands on the previous O'Reilly Books example. I have also attached the updated code below. I hope this answers your questions, and if you have any feedback, please do leave a comment.

hi
thanks for this helpful example .
i am asking if i want to view 2 or more images each view that you made gust one image in each view. and to move from one to another by touching and moving ?
thanks agin
This has been a nice pair of tutorials-- thanks much!
A question related to the change from "cell.text" to "cell.textLabel":
Your example has this code:
UILabel *cellLabel = cell.textLabel;
cellLabel.text = [self.booksModel getBookTitleAtIndex:row];
Can one not set the text directly:
cell.textLabel = [self.booksModel getBookTitleAtIndex:row];
Why do you create the intermediate object?
Thanks for any info!

Peter -
That's a good question - I don't think I needed to create the intermediate object at all. At the time, I probably did it because the cell label was new to me, so I was being really explicit in my thinking about it.
Thanks for the comment!

Hi Elisabeth!
Loved both tutorials. Really helpful for me in getting past a stubborn sticking point. :) And, you've got a GREAT voice and pace for screencasts. Please do more! Regarding the deprecated text property for cell, I believe the correct syntax (without the need of an intermediate syntax) is:
cell.textLabel.text = [self.booksModel getBookTitleAtIndex:row];
Just using cell.textLabel throws an error for me.
