ios – Restkit无法使用适当的映射

我使用Restkit 0.26.0来映射多层的
JSON,这个关键路径会导致麻烦:

productColorImages:   [
{
id: 10,
productId: "232",
color: "green",
url: "exampleURL.com"
},
{
id: 11,
productId: "232",
color: "red",
url: "exampleURL.com"
},
{
id: 12,
productId: "232",
color: "blue",
url: "exampleURL.com"
}
],

我的映射

      RKObjectMapping *transferProductColorImageMapping = [RKObjectMapping mappingForClass:[TransferProductColorImage  class]];
[transferProductColorImageMapping addAttributeMappingsFromDictionary:@{     @"identifier" : @"id",
                                                                            @"URL" : @"URL",
                                                                            @"productId" : @"productId",
                                                                                 @"color" : @"color"

[getProductPageMapping addRelationshipMappingWithSourceKeyPath:@“productColorImages”mapping:transferProductColorImageMapping];

目的地类

@interface TransferProductColorImage : NSObject

@property (nonatomic) NSNumber * identifier; // Mapps to id  ;int 64

@property (nonatomic) NSString * URL;
@property (nonatomic) NSString * productId;
@property (nonatomic) NSString * color;

问题是生成的对象属于正确的类,但属性未填充.

我在日志中搜索并发现了这个:

    2016-05-30 17:42:24.007 thebrandsapp[20697:7047455] T restkit.object_mapping:RKMappingOperation.m:1173 Performing mapping operation: <RKMappingOperation 0x7f9e3b9c11e0> for 'TransferProductColorImage' object. Mapping values from object {
    color = green;
    id = 10;
    productId = 232;
    url = "exampleURL.com";
} to object <TransferProductColorImage: 0x7f9e3b846d60> with object mapping (null)

在Model对象上,productColorImages是一个NSArray:

@property (nonatomic) NSArray <TransferProductColorImage *> * productColorImages;

这很奇怪,因为.如果映射为null,Restkit如何知道要使用的映射.是否有任何理由可以将对象映射设置为null?

更新:我发现标识符和颜色属性已正确映射,标识符和网址未正确映射.

最佳答案 我将URL属性更改为小写:“url”并将其映射为与之前完全相同且有效.似乎全帽属性名称抛出了RestKit.

我突然识别了标识符和id,现在它们也正确映射.
