Given the following code:
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] initWithEntityName:@"Relationship"];
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"%K = %@", @"parentObject.objectBaseUuid", wallUuid];
[fetchRequest setPredicate:predicate];
NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"id" ascending:YES];
[fetchRequest setSortDescriptors:[NSArray arrayWithObject:sortDescriptor]];
self.discussionFRC = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:context sectionNameKeyPath:NULL cacheName:NULL];
I'm getting an exception when trying to create the NSFetchedResultsController:
2012-01-24 11:31:12.184 ECXcollaborate[69599:f203] *** Terminating app due to uncaught exception 'NSObjectInaccessibleException', reason: 'This fetch request (0x6020240) was created with a string name (Relationship), and cannot respond to -entity until used by an NSManagedObjectContext'
The same code runs fine under iOS 5. Anybody has any idea on how to workaround that problem? I need the fetch request to create the fetched results controller and if I believe the exception description, I would have to have the managed object context do a fetch with the fetch request so that I can then use it to create the fetched results controller and do a fetch again? That seems rather counter-productive.
Comments? Ideas?
-Laurent.
