如何使用RestKit映射JSON数组

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"}]

顶级没有钥匙.

[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];

您应该检查Restkit 对象映射文档中的“ Mapping without KVC ”部分。

这是文档中的示例：

[
    { "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"
    }
]

你可以这样映射它：

// 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];
