How do I switch to using Core Data for a simple UITableView instead of an NSArray?

Question

I have an application that uses a UITableView to present data that I have stored in an NSArray.

I would like to switch over to using Core Data to host this information to be presented to the table view, but I'm not that familiar with Core Data.

I've created a new Core Data database within my project, but I'm lost as to how to proceed pst this point. What are the steps required to have my UITableView pull its information from the Core Data database?

Answer 1

You are asking for a lot here :) There are plenty of good tutorials in the wild web that you can read. Here is one :)

Also look at my answer to this question for your alternatives to Core Data

Property Lists is the easiest and most basic one in terms of functionality. It just lets you store primitives, but is good if your TODO list is just a collection of Strings.

Serilization using NSCoding is more powerful, but requires more work from the developer. With NSCoding you can create your own coders/decoders for your business objects that lets you persist the entire state. This would be good if you have your own Todo with a lot of properties, like title, priority, complete-by-date etc.

Answer 2

As has been pointed out, it would take a while to walk you through each step required to do this, so I recommend consulting the many good resources out there before starting to implement Core Data in your application.

There are several questions here that provide a long list of highly recommended resources for getting started with Core Data:

• Starting point in learning Core Data on iPhone?
• New to Core Data for iphone
• Cocoa Core Data newbie how-tos
• Best ressources for learning Core Data?
• Adding Core Data to an existing iPhone app
