Question

我有像这种格式的json字符串：

[{"image":"/0001.jpg","link":"/index.php"},
{"image":"/0001.jpg","link":"/index.php"}]

顶层没有钥匙。

[mapping mapKeyPath:@"image" toAttribute:@"image"];

像这样的映射不起作用，它给我错误：

restkit.object_mapping:RKObjectMapper.m:81 Adding mapping error: Could not find an object mapping for keyPath: ''

如何映射这种类型的json？

Answer 1

使用

[[RKObjectManager sharedManager].mappingProvider addObjectMapping:myObject];

你应该检查＆＃34; Mapping without KVC＆＃34;关于Restkit对象映射文档的部分。

以下是文档中的示例：

[
    { "title": "RestKit Object Mapping Intro",
      "body": "This article details how to use RestKit object mapping...",
      "author": {
          "name": "Blake Watters",
          "email": "blake@restkit.org"
      },
      "publication_date": "7/4/2011"
    }
]

你就像这样映射：

// Our familiar articlesMapping from earlier
RKObjectMapping* articleMapping = [RKObjectMapping mappingForClass:[Article class]];
[articleMapping mapKeyPath:@"title" toAttribute:@"title"];
[articleMapping mapKeyPath:@"body" toAttribute:@"body"];
[articleMapping mapKeyPath:@"author" toAttribute:@"author"];
[articleMapping mapKeyPath:@"publication_date" toAttribute:@"publicationDate"];

[[RKObjectManager sharedManager].mappingProvider addObjectMapping:articleMapping];

对我而言，解决方案是：

添加此响应描述符，使用de array中的对象

[manager addResponseDescriptor:[ObjectInsideTheArray getResponseDescriptor]];

并在成功回复中

NSArray * response =（NSArray *）[mappingResult array ]; //而不是firstObject
