Answer 1

For a start, your colorNames should be an NSMutableArray rather than an NSArray. You can’t add or remove objects from a regular (non-mutable) array; you’d have to recreate it each time you made a change. Switching that will make this easier. For your implementation of -tableView:commitEditingStyle:forRowAtIndexPath:, you’ll then be able to do something like this:

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if(editingStyle == UITableViewCellEditingStyleDelete)
    {
        [colorNames removeObjectAtIndex:indexPath.row];
        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationLeft];
    }
}
