iOS_Class_Hierarchy

用 Ruby 写的脚本，可以提取 iOS 项目中的类继承关系。

用法：

ruby class_hierarchy.rb path_to_iOS_project

抽取出的类关系会在 Ruby 脚本的当前执行目录下生成 Extracted 文件夹，里面是 JSON 格式的结果文件。 对 AFNetworking 提取的类关系：

{
  "NSObject": [
    "AFHTTPRequestOperationManager",
    "AFNetworkReachabilityManager",
    "AFSecurityPolicy",
    {
      "AFHTTPRequestSerializer": [
        "AFJSONRequestSerializer",
        "AFPropertyListRequestSerializer"
      ]
    },
    "AFQueryStringPair",
    "AFStreamingMultipartFormData",
    "AFHTTPBodyPart",
    {
      "AFHTTPResponseSerializer": [
        "AFJSONResponseSerializer",
        "AFXMLParserResponseSerializer",
        "AFXMLDocumentResponseSerializer",
        "AFPropertyListResponseSerializer",
        "AFImageResponseSerializer",
        "AFCompoundResponseSerializer"
      ]
    },
    {
      "AFURLSessionManager": [
        {
          "AFHTTPSessionManager": [
            "AFAppDotNetAPIClient"
          ]
        }
      ]
    },
    "AFURLSessionManagerTaskDelegate",
    "AppDelegate",
    "Post",
    "User",
    "AFNetworkingTests",
    "AFNetworkActivityIndicatorManager"
  ]
}
