将对象数组映射到核心数据条目时遇到了一个奇怪的问题。

用户实体映射和objectManager代码：

RKEntityMapping *objectMapping = [RKEntityMapping mappingForEntityForName:@"User" inManagedObjectStore:[RKObjectManager sharedManager].managedObjectStore];

[objectMapping addAttributeMappingsFromDictionary:@{@"id": @"user_id",
                                                    @"first_name": @"first_name",
                                                    @"middle_name":@"middle_name",
                                                    @"last_name":@"last_name",
                                                    @"phone":@"phone",
                                                    @"job_title":@"job_title",
                                                    @"roles":@"roles",
                                                    @"email":@"email",
                                                    @"created_at":@"created_at",
                                                    @"updated_at":@"updated_at",
                                                    @"avatar_urls":@"avatar_urls",
                                                    @"skills":@"skills",
                                                    @"interests":@"interests",
                                                    @"birth_date":@"birth_date"}];


RKEntityMapping *userMapping = [User entityMapping];

[manager addResponseDescriptor:[RKResponseDescriptor responseDescriptorWithMapping:userMapping
                                                                            method:RKRequestMethodGET
                                                                       pathPattern:@"users/:id"
                                                                           keyPath:nil
                                                                       statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]];

[manager addResponseDescriptor:[RKResponseDescriptor responseDescriptorWithMapping:userMapping
                                                                            method:RKRequestMethodGET
                                                                       pathPattern:@"users"
                                                                           keyPath:nil
                                                                       statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]];

以下是User Entity数组的一个简单示例。

{
  User1,
  User2,
  User3
}

从RestKit查看调试日志，所有内容都映射到正确的值。但是当我查看最终结果时，映射的数组具有正确的项目数，但它们都是User3。同样，数据库也有User3。 User1和User2永远不会存储在数据库中。

我一直想弄清楚哪里出错了。任何帮助表示赞赏。

更新：

 [manager getObjectsAtPath:@"users"
                   parameters:@{@"token":token}
                      success:success failure:failure];

}

在成功块中重申映射结果显示数组中有3个项目，并且都是用户3.我还检查核心数据并确认它只为用户模型添加/更新了一行。

FIX 没有积分可以自己发布答案..所以添加为更新

我忘了为我的用户模型添加identificationAttributes。一旦我把它设置为我的身份，一切都像魅力..... =。=睡眠剥夺是坏的....

Answer 1

在上面的代码中，您设置了一个名为objectMapping的RKEntityMapping。然后设置另一个名为userMapping的RKEntityMapping。您没有再次引用objetMapping。

您发布的代码中缺少某些内容或者从未使用过objectMapping，并且您没有为您的请求设置映射。
