Welcome back to our document-based iCloud app tutorial series!

In this tutorial series we are making a complete document-based iCloud app called PhotoKeeper, with features that go beyond just the basics.

In the first and second part of the series, we made a fully functional UIDocument-based app that works with local files with full CRUD support.

In this third part of the series, it’s finally time to dive into iCloud! We will get almost everything working on iCloud in this tutorial, except for some subtle bits which we’ll leave for the final part of the series.

This project continues where we left off last time, so if you don’t have it already grab the previous code sample and open up the project. It’s iCloud time, baby! Keep reading!

Welcome back to our document-based iCloud app tutorial series!

In this tutorial series we are making a complete document-based iCloud app called PhotoKeeper, with features that go beyond just the basics.

In the first part of the series, we created model classes for our app and a UIDocument wrapper. We also added logic to list and add local files.

In this second part of the series, we will make the app fully functional when it comes to local files. We will improve the look of our master view, implement the detail view, and add support for renaming and deleting files.

If you’re eager to get into iCloud, don’t worry – getting UIDocument support working like we’re doing here is a prerequisite! We’re laying a framework that will make switching to iCloud much easier.

This project continues where we left off last time, so if you don’t have it already grab the previous code sample and open up the project. Let’s begin! Keep reading!

Creating a document-based iCloud app is complicated. There’s a lot of different things to think about, and it’s easy to forget to implement something out or make a mistake along the way.

There are several tutorials on creating iCloud apps out there, including Apple’s Your Third iOS App tutorial and our own iOS 5 by Tutorials, which do a great job of explaining the basics of using iCloud.

What we really need is a tutorial that goes beyond the basics and puts everything together into a complete app that you (gasp) might actually be able to use. This is my attempt to put something like that together for you guys!

In this tutorial, we’re going to create a simple iCloud document based app called PhotoKeeper. It will show you how to do the following:

• Create, Read, Update, and Delete documents – both on iCloud *and* locally
• Create documents consisting of multiple files with NSFileWrapper
• Give previews of documents in the master view in an efficient manner
• Allow a toggle for the user to enable/disable iCloud in Settings
• Move/copy files to and from iCloud when user switches
• Alllow renaming and deleting files – the safe way
• Deal with conflicts and document updates

This is a four part tutorial series. In the first two parts we’ll get things working for local documents only, and then in the second two parts we’ll add iCloud support.

Are you ready to see how to put everything together with iCloud? Let’s get started! Keep reading!
