copied!<p>I finally gave up on FetchController in edit mode since I need to reorder my table cells as well. I'd like to see an example of it working. Instead I kept with having a mutablearray being the current view of the table, and also keeping the CoreData orderItem atrribute consistent. </p> <pre><code>NSUInteger fromRow = [fromIndexPath row]; NSUInteger toRow = [toIndexPath row]; if (fromRow != toRow) { // array up to date id object = [[eventsArray objectAtIndex:fromRow] retain]; [eventsArray removeObjectAtIndex:fromRow]; [eventsArray insertObject:object atIndex:toRow]; [object release]; NSFetchRequest *fetchRequestFrom = [[NSFetchRequest alloc] init]; NSEntityDescription *entityFrom = [NSEntityDescription entityForName:@"Lister" inManagedObjectContext:managedObjectContext]; [fetchRequestFrom setEntity:entityFrom]; NSPredicate *predicate; if (fromRow < toRow) predicate = [NSPredicate predicateWithFormat:@"itemOrder >= %d AND itemOrder <= %d", fromRow, toRow]; else predicate = [NSPredicate predicateWithFormat:@"itemOrder <= %d AND itemOrder >= %d", fromRow, toRow]; [fetchRequestFrom setPredicate:predicate]; NSError *error; NSArray *fetchedObjectsFrom = [managedObjectContext executeFetchRequest:fetchRequestFrom error:&error]; [fetchRequestFrom release]; if (fetchedObjectsFrom != nil) { for ( Lister* lister in fetchedObjectsFrom ) { if ([[lister itemOrder] integerValue] == fromRow) { // the item that moved NSNumber *orderNumber = [[NSNumber alloc] initWithInteger:toRow]; [lister setItemOrder:orderNumber]; [orderNumber release]; } else { NSInteger orderNewInt; if (fromRow < toRow) { orderNewInt = [[lister itemOrder] integerValue] -1; } else { orderNewInt = [[lister itemOrder] integerValue] +1; } NSNumber *orderNumber = [[NSNumber alloc] initWithInteger:orderNewInt]; [lister setItemOrder:orderNumber]; [orderNumber release]; } } NSError *error; if (![managedObjectContext save:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); // Fail } } } </code></pre> <p>If anyone has a solution using fetchController please post it. </p>
