Master data selects objects from an array - iPhone

Question

I was wondering if I can select objects based on a predicate with an array ... for example

code: [Challenger NSPredicateWithFormat: @ "id =% @", arrayOfID];

Will this work? If not, how can I do this?

Answer 1

The correct predicate will be

[NSPredicate predicateWithFormat:@"id IN %@", arrayOfID];

Assuming arrayOfId contains objects of the same type as id (e.g. NSNumbers or NSStrings).

Answer 2

Yes of course you can do it.

It looks like you need a little grounding in Core Data. I found the following tutorial really useful for getting me off the ground with Core Data:
