Understanding and implementing data persistence is a vital part of iOS app development. iOS has many persistent data storage solutions; in this lesson, you’ll use NSCoding as the data persistence mechanism in the FoodTracker app. NSCoding is a protocol that enables a lightweight solution for archiving objects and other structures. Archived objects can be stored on disk and retrieved at a later time.

There are many different ways to save your data to disk in iOS – raw file APIs, Property List Serialization, SQLite, Core Data, and of course NSCoding.

For apps with heavy data requirements, Core Data is often the best way to go.

However, for apps with light data requirements, NSCoding with NSFileManager can be a nice way to go because it’s such a simple alternative.

In this NSCoding tutorial, we’re going to take the “Scary Bugs” app that we’ve been working on in the How To Create A Simple iPhone App Tutorial Series and extend it so that it saves the app’s data to disk.

Along the way, we’ll cover how you can use NSCoding to persist your normal app data, and use NSFileManager to store large files for efficiency.
