我正在使用 Restkit 0.20.x 从 json 映射对象，例如

{
    "d":{
        "results":[
            {
                "Web":[
                    "key1":"value1",
                    "key2":"value2"
                ],
                "Image":[
                    "key1":"value1",
                    "key2":"value2"
                ],
            },
        ],
    },
}

我的主要目的是管理“Web”和“Image”键。我正在尝试映射对象但停留在“结果”键（键“结果”的值是一个只有一个元素作为字典的数组）。在我的情况下如何使用 RestKit 映射对象？

我的失败实现：

WFSD.h

@interface WFSD : NSObject  
@property (nonatomic, strong) WFSResults *results;
@end

WFSResults.h

@interface WFSResults : NSObject
@property (nonatomic, strong) WFSResult    *result;
@end

WFSResult.h

@interface WFSResult : NSObject
@property (nonatomic, strong) WFSWeb    *web;
@property (nonatomic, strong) WFSImage  *image;
@end

我的控制器.m

RKObjectMapping* dMapping = [RKObjectMapping mappingForClass:[WFSD class]];
RKObjectMapping* resultsMapping = [RKObjectMapping mappingForClass:[WFSResults class]];

RKRelationshipMapping* rsMapping1 = [RKRelationshipMapping relationshipMappingFromKeyPath:@"results" toKeyPath:@"results" withMapping:resultsMapping];
[dMapping addPropertyMapping:rsMapping1];

RKObjectMapping* resultMapping = [RKObjectMapping mappingForClass:[WFSResult class]];
[resultsMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:nil toKeyPath:@"result" withMapping:resultMapping]];

RKRelationshipMapping* rsMapping2 = [RKRelationshipMapping relationshipMappingFromKeyPath:@"Image" toKeyPath:@"Image" withMapping:imageMapping];
[resultMapping addPropertyMapping:rsMapping2];

RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor     responseDescriptorWithMapping:dMapping
                                                                                       pathPattern:nil
                                                                                           keyPath:@"d"
                                                                                       statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

看看WFSResults从你的模型类中删除。实际上它只是一个WFSResult对象列表，因此您应该将其建模为：

@interface WFSD : NSObject  
@property (nonatomic, strong) NSArray *results;
@end

您还需要查看WFSResult，因为JSON 中的Web和Image也是数组。所以我希望看到：

@interface WFSResult : NSObject
@property (nonatomic, strong) NSArray  *web;
@property (nonatomic, strong) NSArray  *image;
@end

这样，RestKit 可以在映射期间创建对象，然后它有一个数组来存储对象列表。
