moveRowAtIndexPath - Moving cells between sections

Question

In my UITableView I have this said relationship

Department -< Employees (array of names)

I have set up custom objects for each model.

Answer 1

Thanks to @Paulw11, the solution was that I did not account for the departmentFrom and departmentTo, as what I wanted was to Move Tom from Sales to Marketing;

Thus the fix I have is:

- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath
{
    if (fromIndexPath != toIndexPath ) {

        Department *departmentFrom = [_objects objectAtIndex:fromIndexPath.section];
        Department *departmentTo = [_objects objectAtIndex:toIndexPath.section];

        Employee *employee = [departmentFrom.employees objectAtIndex:fromIndexPath.row];

        [departmentFrom.employees removeObjectAtIndex:fromIndexPath.row];
        [departmentTo.employees insertObject:employee atIndex:toIndexPath.row];
        [tableView reloadData];
    }
}

Accepted Paulw11 answer.
