Join Simon Allardice for an in-depth discussion in this video Responding to changes in the underlying objects, part of Core Data for iOS and OS X.
At the end of the previous example it didn't look like objects were being created, but…in fact they were, and if I quit out of the application and run it again, it will reload…promptly and fetch those objects out of the data store.…So it is actually working, the issue being it wasn't refreshing itself.…So we're going to make that work now, and we're still going to work with that NSFetchedResultsController.…It does make our lives a lot easier when connecting fetch results to a Table View, but like everything…else in iOS, it can exist at several levels of complexity.…
And if we want to get more complexity out of it, like everything else in iOS, we're…going to use a touch of delegation.…So what I'm going to do is in this course's Table View Controller where we're already…using the fetched results controller, I'm also going to volunteer to be a delegate for it.…So everything I'm going to add will be in the CoursesTableViewController class file.…First off, I'm going to jump into the header file and volunteer, say that I can be a delegate…

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.
