Core data select objects from an array - iPhone

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

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

Will it work? If no, how can I do it?

The correct predicate would be 

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

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

Yes, of course you can do it.

Sounds like you need a bit of grounding in Core Data. I found the following tutorial really useful in getting me off the ground with Core Data:
