Join Todd Perkins for an in-depth discussion in this video Understanding the UIDocument class, part of Developing for the Apple iCloud API with iOS (2013).
We've already looked at how to integrate with iCloud using key value pairs.…Another way to integrate with iCloud is by using individual documents.…You can use those documents through the UI document class.…The app I'm working in here is the same as the basic note taking app, except for…I have the MasterView method and MasterViewController that returns the instance.…And again, that instance is set in viewDidLoad.…We did write this code in previous a chapter, so you may already have it there.…
If you don't have access to the Exercise Files, just back up what you did before…working with the key value pairs, and just delete in your copy the key value pair…code from the data class and from AppDelegate.m. In order to work with the…documents in the cloud, you're going to have to create a subclass of UI…document, because the UI document class is an abstract class.…So let's create that subclass now by pressing Command+N on the keyboard.…I'll choose to create a new Objective-C class that I'll call CloudDocument.…
