使用Core Data将Thrift结构保存到文件

Question

I was wondering if there is a nice way to save a Thrift struct to a file/SQLite using iOS's Core Data.

One way is to do the mapping manually between the Thrift declaration and Entities in Core Data, but that's a lot of work and is not very easy to maintain.

A second idea is to save the Thrift as a binary data field in an Entity.

Is there a more elegant way? Eg, a library that takes in a Thrift and takes care of this business?

Thank you, Silviu

Answer 1

You can use NSValue to wrap structures. In turn, NSValue objects can be stored in a transformable attribute.

However, if you want to search or manipulate the contents of struct within Core Data, then you should model the struct as an entity and provide a method in the custom subclass to return the struct if needed.
