I would recommend against this approach (saving the predicateFormat string) if
you care about the internal structure of the predicate (and I think in this
case, you might).
If you have a predicate editor, with the outermost (topmost) predicate being
the compound predicate row (any/all/none of t
If it's still of use, I did this with predicateWithFormat: and -description
wrapped up in a NSValueTransformer subclass. In other words I store a string
representation in the core-data model. I don't know if this is always valid,
but it works well for the predicates in my app.

After some thought I found out that I can use NSkeyedArchiver and
NSKeyedUnarchiver to make an NSData and back to NSPredicate instance. Then it

I am building an application where I am using an NSPredicateEditor. Now I would
like to store the resulting NSPredicate from the NSPredicateEditor in Core
Data. I am not sure how to accomplish that.
I was thinking about using NSCoder, but not sure how to use NSCoder for this as
it usually is use
