按editButtonItem不启用/禁用删除滑动

Question

Using this tutorial，我已经能够覆盖我的表编辑，以允许按下editButtonItem来切换＆＃34;添加行＆＃34;按钮。但是，我还希望它不允许滑动删除，除非打开编辑 - 但始终启用滑动删除。

我已经查看了同样问题的其他Stack Overflow问题，但似乎我已经实现了其他用户建议需要实现的所有内容。我一定错过了什么。

以下是我的表编辑代码：

发现了这个问题。我将editingStyleForRowAtIndexPath方法中的主要if语句更改为self.editing而不是self.aTableView.editing：

// Detemine if it's in editing mode
    if (self.editing) {
        //use the + icon(add icon) on row
        //if this is the additional row created in setEditing:animated:
        if(indexPath.row >= tableData.count){
            return UITableViewCellEditingStyleInsert;
        }
        else {
            //use the delete icon on this row
            return UITableViewCellEditingStyleDelete;
        }
    }
    else
        return UITableViewCellEditingStyleNone;
