How to fetch complete objects (not faults) from CoreData?

I'm new to CoreData concept, and may be I'm getting something wrongly, but I want to fetch fully-qualified array of da开发者_如何学JAVAta from CoreData (not these abstract faults).

My problem is that I displaying a list of objects from CoreData to user in UITableView and at the same time refreshing data in background thread. If user is scrolling TableView at the same time as some of objects were deleted/changed I'm getting CoreData could not fulfill a fault exception

Thanks

Ok, it is actually easy, need to set request's property ReturnsObjectsAsFaults to NO

like this:

[request setReturnsObjectsAsFaults:NO];

I'ts strange nobody answered this simple question
