UICollectionView w/ NSFetchedResultsController & NSBlockOperation. Idea originated from Blake Watters (https://github.com/AshFurrow/UICollectionView-NSFetchedResultsController/issues/13)
- (void)controllerWillChangeContent:(NSFetchedResultsController *)controller
{
self.shouldReloadCollectionView = NO;
self.blockOperation = [[NSBlockOperation alloc] init];
}
- (void)controller:(NSFetchedResultsController *)controller didChangeSection:(id<NSFetchedResultsSectionInfo>)sectionInfo
atIndex:(NSUInteger)sectionIndex forChangeType:(NSFetchedResultsChangeType)type
{
__weak UICollectionView *collectionView = self.collectionView;
