RestKit映射關係錯誤

我真的不明白爲什麼我有一個錯誤：/ 有人可以看看它嗎？RestKit映射關係錯誤

JSON文件：

{ 
"total_count": 3, 
"incomplete_results": false, 
"winners": [ 
    { 
     "windate": "2015-05-26 17:11:30.0", 
     "gift": "foo", 
     "email": "foo", 
     "giftack": "foo", 
     "lastname": "foo", 
     "gender": "foo", 
     "firstname": "foo", 
     "updategiftdate":null 
    } 
], 
"nbWinners": 3 
}

映射文件：

//Winner List Mapping 
RKEntityMapping *winnerListMapping = 
    [RKEntityMapping mappingForEntityForName:@"WinnerList" 
         inManagedObjectStore:managedObjectStore]; 
winnerListMapping.identificationAttributes = @[@"nbWinners"]; 
[winnerListMapping addAttributeMappingsFromDictionary:@{ 
            @"total_count" : @"totalCount", 
          @"incomplete_results" : @"incompleteResults", 
             @"nbWinners" : @"nbWinners" }]; 

//Winner Mapping 
RKEntityMapping *winnerMapping = 
    [RKEntityMapping mappingForEntityForName:@"Winner" 
         inManagedObjectStore:managedObjectStore]; 
winnerMapping.identificationAttributes = @[@"winDate"]; 
[winnerMapping addAttributeMappingsFromArray:@[ 
              @"windate", @"gift", @"email", @"giftack", @"lastname", @"gender", @"firstname", @"updategiftdate"]]; 

//Link Winner to WinnerList 
[winnerListMapping addPropertyMapping: 
    [RKRelationshipMapping relationshipMappingFromKeyPath:@"winners" 
               toKeyPath:@"winners" 
               withMapping:winnerMapping]]; 

//Run Mapping 
RKResponseDescriptor *winnerListResponseDescriptor = 
[RKResponseDescriptor responseDescriptorWithMapping:winnerListMapping 
              method:RKRequestMethodGET 
             pathPattern:@"example.json" 
              keyPath:nil 
             statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful) 
]; 
[objectManager addResponseDescriptor:winnerListResponseDescriptor];

)

在此先感謝您的幫助！

我打賭這是錯誤。

//Link Winner to WinnerList 
[winnerListMapping addPropertyMapping: 
    [RKRelationshipMapping relationshipMappingFromKeyPath:@"winners" 
               toKeyPath:@"winners" 
               withMapping:winnerMapping]];

具體的toKeyPath:@"winners"你的贏家模型沒有winners屬性。

relationshipMappingFromKeyPath是一個WinnerList屬性，toKeyPath是一個json屬性，不是嗎？其目的是將WinnerMapping的所有內容（許多Winner對象）都是WinnerList對象。所以贏家不需要贏家屬性 – StrawHara

你是對的。我注意到一個無法識別的選擇器錯誤「[贏家贏家]」，並認爲是這樣。我猜你已經解決了這個問題，如果不是贏家映射對我來說看起來不對。也許這是導致解析錯誤。嘗試使用與上述winnerListMapping相同的字典。 –

是的，我解決了這個問題。但這不是真正的問題;）我真的不明白爲什麼它不工作，但我改變了我的方式來做到這一點，現在它的工作。謝謝：） – StrawHara
