ios - 没有主键的 MagicalRecord 导入

Question

有没有办法用没有primaryKey或relatedByAttribute的Magical Record导入数据？

我的 JSON 看起来像这样。如您所见，这是员工也可以访问的服务列表。我也没有唯一的 ID 可以关联。

{
   "status":0,
   "statusMessage":"Call success",
   "details":{
      "items":[
         {
            "status":0,
            "statusMessage":"Employee service schedule list returned",
            "details":{
               "itemsReturned":2,
               "items":[
                  {

导入这些没有唯一 ID 的神奇记录的最佳方法是什么？

Answer 1

MagicalRecord 导入应该仍然可以处理这些数据。由于您已经通过 json 键获得相关的对象，我们可以知道您想要将核心数据实体与什么相关联。此外，只要您正确地将 json 属性映射到核心数据属性，这也为导入库提供了足够的信息来确定什么应该与导入的内容相关。
