json - 需要帮助使用 Alamofire 使用 Swift 解析 JSON

Question

我正在尝试从 Google 新闻中检索一篇文章并使用 Swift 对其进行解析。我正在使用 Alamofire。我知道解析时要做什么的基础知识，但输出看起来有点复杂，我不知道如何访问“标题”值。任何帮助，将不胜感激。谢谢!

这是 JSON 输出:

responseData =     {
        cursor =         {
            currentPageIndex = 0;
            estimatedResultCount = 445755633;
            moreResultsUrl = "http://news.google.com/nwshp?oe=utf8&ie=utf8&source=uds&q=sports&hl=en&start=0";
            pages =             (
                                {
                    label = 1;
                    start = 0;
                },
                                {
                    label = 2;
                    start = 1;
                },
                                {
                    label = 3;
                    start = 2;
                },
                                {
                    label = 4;
                    start = 3;
                },
                                {
                    label = 5;
                    start = 4;
                },
                                {
                    label = 6;
                    start = 5;
                },
                                {
                    label = 7;
                    start = 6;
                },
                                {
                    label = 8;
                    start = 7;
                }
            );
        };
        results =         (
                        {

            }
        );
    };
    responseDetails = "";
    responseStatus = 200;
}

我真的很困惑，因为它看起来不像我在网上看到的大多数例子。

从 github 添加 SwiftyJSON 并执行下面的操作

     import SwiftyJSON

      func parseJson() {

        Alamofire.request(.POST, "urlString", parameters:   parameter, encoding: .JSON)
        .responseJSON { response in


            //Check Response

            if response.result.isFailure == true {
                return
            }

            let json = JSON(response.result.value!)

          let cursorEntity = json["Cursor"]
          let currentIndex = json["cursor"].currentPageIndex
          let pageEntity =  json["cursor"]["pages"]
          let resultsEntity = json["cursor"]["results"]
       }
    }
