- [Voiceover] Hi, this is Simon Allardice, and welcome to Core Data for iOS and OS X. In this course, I'll begin by talking about what core data is, and how it can help us. We'll explore the vocabulary and the ideas of core data, terms like managed objects, predicates, and what these mean. But we'll quickly get hands on. That starts by modeling our data, using the tools and xcode to describe our applications in a way that Core Data understands, and enables us to easily save, or persist that information. And if we've saved it, we need to be able to retrieve it.
We'll see how to fetch, bring our data back, and tie it into a user interface. Beyond the most trivial of applications, Core Data is what you should be using to work with data in your iOS and Mac applications. It's an essential competency for an Apple developer. Let's get started.
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.
