Join Simon Allardice for an in-depth discussion in this video Switching modes in a view controller, part of Core Data for iOS and OS X.
So we currently have this DetailViewController just showing up un-clickable, just displaying the data.…I'm also going to make this work in Edit mode so it allows us to edit the item that we are currently looking at.…So jumping back onto the Storyboard, I am going to work with this DisplayEditViewController again,…open up my Utilities panel, and I want a couple of buttons I am going to drag on. I can just…remind myself where these text fields are because I currently have them without a boundary.…I am going to drag on a couple of buttons just up at the top here, and just so they don't…interfere a little bit, I will make them a little bit smaller.…
One says edit, the other says done, I am actually going to change the done button so that it is hidden…and then shift into Assistant View so we should be looking at the DisplayEditViewController…on the right-hand side, and I'm going to drag from both of these buttons and create actions for both of them.…Although I also want outlets as well, so let's do both of them.…

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.
