Join Simon Allardice for an in-depth discussion in this video Using the exercise files, part of Core Data for iOS and OS X.
If you're a Premium Member of lynda.com, or if you're watching this tutorial on a DVD, then you'll have access to exercise files for this title. I've expanded them here onto my desktop, and inside this folder, each of the relevant chapters will have its own folder, and there are some projects that I'll be working with during the course to provide some simple starter code to save us some time. We'll point out any files at the relevant time just by showing you the path to the file location. There are also some finished examples, if you want to compare and contrast what you've done with what I've done.
But they are all just for convenience. If you don't have access to the exercise files, you can follow along from scratch or with your own assets.

Q: In the CoursesViewController.m file, I receive a message that the method dismissModalViewControllerAnimated is no longer supported by Apple. Is there a newer method to use?
A: You may have received the warning that a call to the dismissModalViewControllerAnimated: method is now deprecated.
This is a recently deprecated method, so the code _will_ continue to work using that call, but to remove the warning, change the code from:
to the current recommended version:
[self dismissViewControllerAnimated:YES completion:nil];
It should take care of that message.
