I have a table view. I want to add data into it. I have surfed net and found some sample codes for that. However many of the them are using NSKeyedUnarchiver (encoding, decoding). Why do we need to do this? Any specific reason?

It’s a way to save and restore data in your app. There are several ways to store and retrieve data in iOS; Core Data, SQLite, plists.
NSKeyedArchiveris an easy to understand and easy to use class for data persistence. I’d say the reason you’re seeing it so much is because it’s an easy concept for beginners. The other data persistence methods are less easy to understand.
