How to make UITableView rearrange?

Question

I am trying to make my UITableView editable so that you can move cells. Right now, when I click the edit button, it allows me to delete, but not reorder.

I have the following methods:

Code:
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
    return YES;
}

- (void)setEditing:(BOOL)editing animated:(BOOL)animate
{
    [self.routineTableView setEditing: !self.routineTableView.editing animated:YES];

    if (self.routineTableView.editing)
        [self.navigationItem.leftBarButtonItem setTitle:@"Done"];
    else
        [self.navigationItem.leftBarButtonItem setTitle:@"Edit"];
}

-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
 {
     if (editingStyle == UITableViewCellEditingStyleDelete) 
     {
         NSManagedObjectContext *context = [self.fetchedResultsController managedObjectContext];
         [context deleteObject:[self.fetchedResultsController objectAtIndexPath:indexPath]];
         NSLog(@"fetched results : \n%@\n",[self.fetchedResultsController fetchedObjects]);

         NSError *error = nil;

         if (![managedObjectContext save:&error]) 
         {
             // Handle the error.
         }
    }

- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath
{
    return YES;
}

Answer 1

To properly reorder rows, the table view data source must implement methods such as:

-(BOOL)tableView:(UITableView *)tableView
canMoveRowAtIndexPath:(NSIndexPath *)indexPath;
-(void)tableView:(UITableView *)tableView
moveRowAtIndexPath:(NSIndexPath *)fromIndexPath
       toIndexPath:(NSIndexPath *)toIndexPath;

and his delegate can implement:

-(NSIndexPath *)tableView:(UITableView *)tableView
targetIndexPathForMoveFromRowAtIndexPath:(NSIndexPath *)sourceIndexPath
                     toProposedIndexPath:(NSIndexPath *)proposedDestinationIndexPath;

There is also this page giving you code examples.
