Question

我遇到了JSON和Swift 2的问题。我从服务器获取此数组

[{"KidName":"Jacob","KidId":1,"GardenID":0},
{"KidName":"Sarah","KidId":2,"GardenID":0},
{"KidName":"Odel","KidId":3,"GardenID":0}]

我熟悉JSON，我知道它不是推荐的获取JSON的方法，因为它应该是类似的

{"someArray":[{"KidName":"Jacob","KidId":1,"gardenID":0}, .....

所以我的第一个问题是可以运行第一个JSON我发布并获取KidName号而不编辑JSON并添加一个JSON OBJECT来保存数组？

我的第二个问题是Swift 2，我怎样才能获得KidName（在我编辑JSON以获得数组的持有者之后）？

这是我的代码...（请阅读我添加的说明）顺便说一句，我也熟悉SwiftyJSON ......

// Method I've build to get the JSON from Server, the Data is the JSON
       sendGetRequest { (response, data ) -> Void in

        // need to convert data to String So I can add it an holder 
          if let str = NSString(data: data, encoding: NSUTF8StringEncoding)            as? String {

                  /**
                 after editing the str, i'm Having a valid JSON, let's call it fixedJSON
                  */
                 let fixedJSON = "{\"kidsArray\":\(dropLast)}"

                  // Now I'm converting it to data back again
                    let jsonTodata = fixedJSON.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!

             // After Having the data, I need to convert it to JSON Format
                do{
                               let dataToJson = try NSJSONSerialization.JSONObjectWithData(jsonTodata, options: []) as!  [String:AnyObject]
                //Here I'm getting the KidID
                 if let kidID = jsonSe["kidsArray"]![0]["KidId"]!!.integerValue {
                    print("kidID in first index is: \(kidID)\n")
                }

                //NOW trying to get the KidName which not working
                  if let kidname = jsonSe["kidsArray"]![0]["KidName"]!!.stringValue {
                    print("KidName is \(kidname)\n")
                }

              }

所以你可以看到，我无法获得KidName。任何帮助都会令人欣慰。

您可以使用以下功能获取＆＃39; someArray＆＃39;数组，然后使用此getStringFromJSON函数来获取＆＃39; KidName＆＃39;值。

func getArrayFromJSON(data: NSDictionary, key: String) -> NSArray {

    if let info = data[key] as? NSArray {
        return info
    }

    else {
        return []

    }

}

 let someArray = self.getArrayFromJSON(YourJSONArray as! NSDictionary, key: "someArray")


func getStringFromJSON(data: NSDictionary, key: String) -> String {

    if let info = data[key] as? String {
        return info
    }

    return ""
}

 let KidName = self.getStringFromJSON(someArray as! NSDictionary, key: "KidName")

希望这对你有用。

带有Swift 2的JSON，数组结构
