将返回的文本解析为 Swift 中的 JSON 对象？

Question

已解决：

我解决了这个问题：

if let returnedData = NSJSONSerialization.JSONObjectWithData(data, options: nil, error: nil) as? NSString? {
                let dataString = NSString(data: data!, encoding: NSUTF8StringEncoding)!
                let trimmedDataString = ((dataString.stringByReplacingOccurrencesOfString("YAHOO.Finance.SymbolSuggest.ssCallback", withString: "") as NSString).stringByReplacingOccurrencesOfString("(", withString: "") as NSString).stringByReplacingOccurrencesOfString(")", withString: "")
                let dataFromDataString = trimmedDataString.dataUsingEncoding(NSUTF8StringEncoding)!
                if let jsonObject: AnyObject = NSJSONSerialization.JSONObjectWithData(dataFromDataString, options: .allZeros, error: nil)  {
                    if let resultSet = jsonObject["ResultSet"] as! NSDictionary? {
                        println(resultSet)
                    }
                }

            }

原题：

我目前正在使用 Yahoo! Finance 的 YQL 到 return 股票数据。我能够查询股票并成功 return 想要的信息，但前提是我知道股票的代码（AAPL、GOOG、FDX）。但是，我希望能够复制 iOS' Stocks 应用程序的搜索功能，它允许您在键入字符串时执行股票代码的实时搜索。

当使用 this URL 检索信息时，我得到一个 JSON 对我没有用的响应：

{"query":{"count":0,"created":"2015-06-01T23:49:49Z","lang":"en-us","results":null}}

但是，我已经能够从 this URL 中找到我要查找的内容，但数据并未以 JSON 格式 returned我目前知道如何处理：

YAHOO.Finance.SymbolSuggest.ssCallback({"ResultSet":{"Query":"k","Result":[{"symbol":"K","name":"Kellogg Company","exch":"NYQ","type":"S","exchDisp":"NYSE","typeDisp":"Equity"},{"symbol":"KNDI","name":"Kandi Technologies Group, Inc.","exch":"NMS","type":"S","exchDisp":"NASDAQ","typeDisp":"Equity"},{"symbol":"KO","name":"The Coca-Cola Company","exch":"NYQ","type":"S","exchDisp":"NYSE","typeDisp":"Equity"},{"symbol":"KMI","name":"Kinder Morgan, Inc.","exch":"NYQ","type":"S","exchDisp":"NYSE","typeDisp":"Equity"},{"symbol":"KMB","name":"Kimberly-Clark Corporation","exch":"NYQ","type":"S","exchDisp":"NYSE","typeDisp":"Equity"},{"symbol":"GMCR","name":"Keurig Green Mountain, Inc.","exch":"NMS","type":"S","exchDisp":"NASDAQ","typeDisp":"Equity"},{"symbol":"KORS","name":"Michael Kors Holdings Limited","exch":"NYQ","type":"S","exchDisp":"NYSE","typeDisp":"Equity"},{"symbol":"KLAC","name":"KLA-Tencor Corporation","exch":"NMS","type":"S","exchDisp":"NASDAQ","typeDisp":"Equity"},{"symbol":"KRFT","name":"Kraft Foods Group, Inc.","exch":"NMS","type":"S","exchDisp":"NASDAQ","typeDisp":"Equity"},{"symbol":"^KLSE","name":"FTSE Bursa Malaysia KLCI","exch":"KLS","type":"I","exchDisp":"Kuala Lumpur Stock Exchange ","typeDisp":"Index"}]}})

我整天都在寻找一种方法来将这个 returned 字符串转换为 JSON 对象，以便在我的应用程序中使用。

因为它没有以我知道如何用 NSJSONSerialization.JSONObjectWithData(data, options: nil, error: nil) 解析的 JSON 格式返回，所以我一直在寻找一种创建 JSON 对象的方法从字符串。有没有我可以指出的方向，我只是错过了？

试试这个：

if let returnedData = NSJSONSerialization.JSONObjectWithData(data, options: nil, error: nil) as? NSString? {
    let dataString = NSString(data: data!, encoding: NSUTF8StringEncoding)!
    if let jsonObject: AnyObject = NSJSONSerialization.JSONObjectWithData(dataString, options: .allZeros, error: nil)  {
    if let resultSet = resultSet[yourDictionaryObject objectForKey:@"YAHOO.Finance.SymbolSuggest.ssCallback"]
        //This should return a array of dictionary 
    }
}
