UITableView 删除cell 的问题

 // 错误写法

-(void)deleteTabelCellAction:(NSIndexPath *)indexPath{    [_tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];    [_questionArray removeObjectAtIndex:indexPath.row];}

// 正确写法

-(void)deleteTabelCellAction:(NSIndexPath *)indexPath{    [_questionArray removeObjectAtIndex:indexPath.row];    [_tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationLeft];}
