How to store a typedef enum in CoreData

Question

I have a typedef enum I use to represent a state of a job in a queueing system and it is defined as

typedef enum  {
kTWjobStateRunning,
kTWjobStateQueued,
kTWjobStateError
}TWjobState;

Everything is fine, but now I would like to store it as an attribute in CoreData. My first idea is that an enum is basically an integer, so would wrapping the TWjobState in a NSNumber work? Do I have to use casts to persuade the compiler?

Best practice question
I saw this use of enums often in Cocoa and Foundation classes and also the use of bitmasks. Is there a more modern, more object-oriented way to achieve the same?

Thanks for your help.

Answer 1

Storing enums in an NSNumber is the correct way to do this.
