iOS RestKit實體管理器映射對象陣列

Question

我有一個奇怪的問題，將對象數組映射到核心數據項。

用戶實體映射和的ObjectManager代碼：

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)]]; 

下面是用戶實體的陣列的簡單例子。

{ 
    User1, 
    User2, 
    User3 
} 

查看來自RestKit的調試日誌，所有內容都映射到正確的值。但是當我查看最終結果時，映射數組的項目數量正確，但它們都是User3。同樣，數據庫也有User3。用戶1和用戶2從不存儲在數據庫中。

我一直在想弄清楚我出錯的地方。任何幫助表示讚賞。

UPDATE：

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

    }, 
    "id": 632, 
    "roles": [ 
     "company_admin" 
    ], 
    "created_at": "2013-10-23T16:07:12.295-05:00", 
    "updated_at": "2013-11-01T20:11:26.607-05:00",

    "first_name": "User", 
    "last_name": "Three", 
    "email": "", 
    "phone": "", 
    "job_title": "" 
}

爲了重申在成功塊映射的結果示出了在陣列3項和所有都是用戶3。我也查詢核心數據，並確認它僅添加/爲用戶模型更新了一行。

FIX 不必分發帖回答自己..所以加入作爲更新

我忘了補充identificationAttributes我的用戶模型。一旦我將它設置爲我的ID，一切都像魅力..... =。=睡眠剝奪是不好的......

Answer 1

在上面的代碼中，您設置了一個名爲objectMapping的RKEntityMapping。然後，您設置另一個名爲userMapping的RKEntityMapping。您不要再次引用objetMapping。

您發佈的代碼中缺少某些內容，或者從未使用過objectMapping，並且您沒有爲您的請求設置映射。
