How to record and later get sound in / c Core Data?

Question

Objective-C

All the best!
Here I am trying to work with Core Data, I have already learned how to record and also retrieve some data. Please tell me how to save it there and then get the sound?
So I understand that the algorithm is similar to saving pictures, also NSData and Binary Data

Answer 1

Two options:
1) Translate the sound into NSData and store it as NSData
2) Implement the NSCoding protocol, specify Transforamble in the model, save as a sound object
In the model, it is better to take the sound object into a separate class and check the Allows External Storage checkbox.
