ios - How do I save and fetch audio data to/from CoreData with Objective-C?

Question

I'm a new to iOS development.

How can I save and fetch audio data to/from CoreData with Objective-C?

I just know that I have to use NSData and Binary Data.

As @shallowThought says in his comment, you should generally not store big binary data objects in Core Data. Save the sound files to your app's documents directory or one of the other sandbox directories, and then store a URL or path to the file in Core Data.
