Answer 1

To tell the fetch request to sort your data…

NSFetchRequest *fetchRequest = [NSFetchRequest fetchRequestWithEntityName:@"myEntity"];
NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"index" ascending:YES];
fetchRequest.sortDescriptors = [NSArray arrayWithObject:sortDescriptor];

Now when you fetch, the data will be sorted according to the index field.
