Learning Core Data for iOS teaches you all you need to know to build database-enabled iOS apps with Core Data. This is the first Core Data book to fully reflect Apple's latest platform innovations, especially the dramatic improvements to iCloud support in the next version of iOS. Hands-on from start to finish, this tutorial teaches you step-by-step as you create a modern iOS app using ARC, iOS and Xcode 4 with Storyboards. You'll walk through: - Discovering how Core Data simplifies the incorporation of database functionality
- Adding Core Data to an existing project
- Configuring and upgrading data models
- Using the MOC and storyboarding
- Working with the Table Views and Views design patterns
- Preloading your data
- Instrumenting your apps and overcoming performance pitfalls
- Seamlessly backing up and restoring data
- Generating PDFs, emails, and more
One step at a time, you'll extend your skills — even mastering advanced techniques such as iCloud Dropbox integration, backup/restore, Table Views change notification, and web service integration. A downloadable version of the main project will be available at the end of each chapter, so you can see exactly what your app project should look like — and get cookbook-style code for your own future projects, too. Exercises at the end of each chapter offer opportunities to explore further — and making the book as useful for iOS app development courses as it is for self-learners.
