NSFetchedResultsController refresh refetch?

Question

I want to refetch data from my NSFetchedResultsController using a different predicate which is set using a boolean value. How do I refresh NSFetchedResultsController to fetc

Answer 1

Here's how we do it in an application:

// Assuming these exist
NSPredicate * predicate;
NSString * cacheName;

[[fetchedResultsController fetchRequest] setPredicate:predicate];
[NSFetchedResultsController deleteCacheWithName:cacheName];

NSError * error = nil;
[fetchedResultsController performFetch:&error];
if (error) {
    // report error
}
