I’m going to build this tutorial on the previous two so if you haven’t checked them out yet, you can see the first one here and the second one here. You can also download the source code on the bottom of each tutorial.

What we’ve done so far

We used UITableViewController to build out our root view controller that lists all the DVDs from our data file. Then we customized each cell by adding a DVD cover and some basic info about each movie. Tapping a row in the table caused the app to go to a detail page which was also a table displaying expanded info about the selected movie. That’s the part we’re going to work on now.

1. Download some source code to get your started

Since we’re going to be completely removing the detail view controller we used in the previous tutorials, let’s just start from there. Instead of walking you through deleting the controller and removing the appropriate functionality, download this source code that will get you started. You’ll get the root view controller with customized cells in it. However, tapping on any of the rows won’t do anything, yet. Download the primer project here: MyDVDLibrary03Primer.

2. Enhance test data file

Since our test data file only contains title, length, image and release date for each movie, that’s not going to cut it when trying to design a detail view page. We’ll at least want to add the description of the movie and maybe also its genre. This can be very tedious to do in a plist like we’re using right now but it will get a lot easier once we start using Core Data that I will cover in later tutorials.

I won’t make you add all the data by hand so for a shortcut, download the completed plist file here and replace your existing one that can be found in Xcode under the Resources folder: TestData.plist.

3. Create new DetailViewController class

In Xcode’s file browser on the left, right-click on the Classes folder and choose Add -> New File… . Under Cocoa Touch Classes group choose UIViewController subclass and make sure to check the With XIB for user interface checkbox. This will not only create our subclass but also the NIB file that we’ll use to layout our UI components.
