Question

后端的JSON如下

  "data": [
    {
      "id": 108,
      "userId": "84945dd7-4ebe-418a-b5ec-bd418d226778",
      "notificationType": 0,
      "messagingService": 1,
      "status": 2
    },
    {
      "id": 109,
      "userId": "84945dd7-4ebe-418a-b5ec-bd418d226778",
      "notificationType": 0,
      "messagingService": 2,
      "status": 2
    },
    {
      "id": 110,
      "userId": "84945dd7-4ebe-418a-b5ec-bd418d226778",
      "notificationType": 1,
      "messagingService": 1,
      "status": 2
    },
    {
      "id": 111,
      "userId": "84945dd7-4ebe-418a-b5ec-bd418d226778",
      "notificationType": 1,
      "messagingService": 3,
      "status": 2
    }
  ]

我从后端

获取记录到数组

@property(nonatomic, strong)NSArray *userPreferences;

我想要成功的是用相同的键显示那些记录＆＃34; notificationType＆＃34;在单个单元格中呈现不同类型的其他键＆＃34; messagingService＆＃34;。最后点击任何indexPath.row并知道我选择了哪条记录并执行我的主动/非主动选项。

谢谢你的消息Jordan Bonitatisfor，基于你的例子，这就是我提出的：

strip_attributes except: [:password_digest]

如何将resultDict现在附加到正确的单元格。

Answer 2

经过严格的测试和试验以及错误后，我设法通过Generics（之前从未使用过）thx的帮助成功完成了我想要的所有帮助。

NSMutableDictionary<NSNumber*, NSMutableDictionary<NSNumber *, KYNotificationPreference *> *> *preferences = [NSMutableDictionary new];

                                       for(NSDictionary *rawPreference in (*response).data){
                                           KYNotificationPreference *preference = [KYDeserializer notificationPreferenceFromSerializedObject:rawPreference];
                                           NSMutableDictionary *notificationTypeDictionary = preferences[@(preference.notificationType)];
                                           if(!notificationTypeDictionary){
                                               notificationTypeDictionary = [NSMutableDictionary new];
                                               [preferences setObject:notificationTypeDictionary forKey:@(preference.notificationType)];
                                           }
                                           [notificationTypeDictionary setObject:preference forKey:@(preference.messagingService)];
                                       }
