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.
