    <p>I know how to sort Core Data objects in a tableview by NsDate, but this by default seems to create a new section for each object. I want to sort them by a medium formatted date with NSDateFormatter. How would I do this?</p> <p>For example, if I have 3 objects created on the same day, I want them to be in the same section with the section title being that Day, no time needed.</p> <p>Each object has an NSDate property. Thanks for your help.</p> <p>This is the code I have in fetchedResultsController with rgeorge's suggestions. What am I missing here?</p> <pre><code>- (NSFetchedResultsController *)fetchedResultsController { if (fetchedResultsController != nil) { NSLog(@"get old fetched controller"); return fetchedResultsController; } else{ NSLog(@"get new fetched controller"); } NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"InTextEntity" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; [fetchRequest setFetchBatchSize:20]; NSSortDescriptor *dateDescriptor = [[NSSortDescriptor alloc] initWithKey:@"dateModified" ascending:NO]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:dateDescriptor, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:@"mediumFormattedDate" cacheName:@"Root"]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; NSError *error = nil; if (![fetchedResultsController performFetch:&amp;error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); } return fetchedResultsController; </code></pre> <p>} </p>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
