Question

我正在使用RESTKit执行GET请求，我需要帮助映射JSON响应。以下是我需要映射的响应：

{"limit_hit":false,"providers":
    [{"id":876553,
    "name":"Cooper, Bradley N, DDS",
    "specialty_groups":["Other Provider"],
    "tags":[],
    "has_comments":false,
    "number_of_comments":0,
    "locations":
        [{"address":"1234 Rifle Range Road, El Cerrito, CA, 94530",
        "providers_at_address_count":1,
        "client_product_count":0,
        "non_client_product_count":2,
        "address_lines":["1234 Rifle Range Road, El Cerrito, CA, 94530"],
        "address_id":234578,
        "specialty_groups":
            [{"specialty_group":"Other Provider"}],
        "provider_types":
            [{"provider_type":"Other Provider"}]},

        {"address":"7501 Mission Rd, Shawnee Mission, KS, 66208",
        "providers_at_address_count":2,
        "client_product_count":0,
        "non_client_product_count":2,
        "address_lines":["7654 Main S, El Cerrito, CA, 94530"],
        "address_id":654432,
        "specialty_groups":
            [{"specialty_group":"Other Provider"}],
        "provider_types":
            [{"provider_type":"Other Provider"}]
        }]
    }]
}

我希望能够映射两个地址，但我不知道如何。我目前能够做的就是映射id，name，has_comments和number_of_comments（我使用＆＃34;提供商＆＃34;的关键路径）。这是我目前的地图提供商：

+ (RKMapping *)searchMapping
{
    RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[ProviderSearch class]];
    [mapping addAttributeMappingsFromDictionary:@{
     @"id": @"doctorID",
     @"name": @"name",
     }];
    return mapping;
}

我到底做错了什么，我该如何解决？

Answer 1

创建另一个方法以返回locations的映射，然后将该映射关联到此原始映射。像这样：

// ProviderLocation.m
+ (RKObjectMapping *)objectMapping
{
    RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[ProviderLocation class]];
    [mapping addAttributeMappingsFromDictionary:@{
     @"address": @"address",
     ...
     }];
    return mapping;
}

关系：

+ (RKObjectMapping *)searchMapping
{
    RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[ProviderSearch class]];
    [mapping addAttributeMappingsFromDictionary:@{
     @"id": @"doctorID",
     @"name": @"name",
     }];

    RKObjectMapping *locationsMapping = [ProviderLocation objectMapping];
    [mapping addPropertyMapping:
        [RKRelationshipMapping relationshipMappingFromKeyPath:@"locations" toKeyPath:@"locations" withMapping:locationsMapping]];

    return mapping;
}

请记住在名为ProviderLocation.h的{{1}}中创建一个NSArray属性。

我之前从未使用过RKObjectMapping，但你所拥有的“位置”是一个字典对象数组。所以你需要一个

NSArray loc = [myJson objectForKey:@"locations"];
for(NSDictionary *dict in loc){
    //here each dict obj will have your "address",  "providers_at_address_count" and etc... so if you want to access any of them you can call...
    NSString *addr = [dict objectForKey:@"address"];
 }

现在以某种方式将其转换为您使用RXObjectMapping进行的操作，并且您是黄金= P

使用RESTKit映射包含括号的JSON响应
