ios - UITableView reloadData 的 UIMutableIndexPath 发布

Question

[UIMutableIndexPath release]: message sent to deallocated instance 0x205a2930当我尝试执行时，有时会因此错误而崩溃：

[self.detailsTableView reloadData];

cellForRowAtIndexPath 方法在这里：

- (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    DetailResultCell *cell = (DetailResultCell*) [aTableView dequeueReusableCellWithIdentifier:DETAIL_RESULT_CELL_ID];
    if(cell == nil)
    {
        [[NSBundle mainBundle]loadNibNamed:DETAIL_RESULT_CELL_ID owner:self options:nil];
        cell = detailResultCell;
    }
    cell.detailsResultatViagerViewController = self;
    [cell cellWithIndexPath:indexPath andChamp:[[self.resultats objectAtIndex:indexPath.section] objectAtIndex:indexPath.row]];

    return cell;
}

我怎样才能避免这种情况？我尝试在周围放置一个 try/catch 块，[self.detailsTableView reloadData];但崩溃仍然发生......
