Question

var mobileOprator = [String]() // My Array

//My Response
Optional("[\n  \"Aircel\",\n  \"Airtel\",\n  \"BSNL\",\n  \"Idea MTV\",\n  \"MTNL\",\n  \"MTS\",\n  \"Reliance CDMA\",\n  \"Reliance GSM\",\n  \"Reliance JIO\",\n  \"TATA CDMA\",\n  \"TATA DOCOMO\",\n  \"Telenor\",\n  \"Videocon\",\n  \"Vodafone\"\n]")

我想将它解析为我的mobileOprator数组。

Answer 1

Optional("[\n  \"Aircel\",\n  \"Airtel\",\n  \"BSNL\",\n  \"Idea MTV\",\n  \"MTNL\",\n  \"MTS\",\n  \"Reliance CDMA\",\n  \"Reliance GSM\",\n  \"Reliance JIO\",\n  \"TATA CDMA\",\n  \"TATA DOCOMO\",\n  \"Telenor\",\n  \"Videocon\",\n  \"Vodafone\"\n]")

与此相同，只是为了更好地可视化数据

Optional("[  
              \"Aircel\",
              \"Airtel\",
              \"BSNL\",
              \"Idea MTV\",
              \"MTNL\",
              \"MTS\",
              \"Reliance CDMA\",
              \"Reliance GSM\",
              \"Reliance JIO\",
              \"TATA CDMA\",
              \"TATA DOCOMO\",
              \"Telenor\",
              \"Videocon\",
              \"Vodafone\"
            ]")

由于数据是可选的，我们应检查它是否存在以及它是否开始解析。这可以使用以下语法完成：

if let a = optional_a {

}

其中optional_a可以是任意可选数据类型，a是nonoptional。基本上Swift检查它是nil，如果不是a。

接下来，对于解析，String类有一个名为replacingOccurences(of: String!, with String!)的函数。将此视为查找并替换所有功能。这可用于删除任何无关的字符，例如＆＃34; \ n＆＃34;，＆＃34; \＆＃34;＆＃34;，＆＃34; \＆＃34;，＆＃34; [ ＆＃34;，＆＃34;]＆＃34;，＆＃34; ＆＃34 ;.删除后，我们需要将字符串拆分为＆＃34;，＆＃34;并将其映射到数组中。

此代码应该有效：

var optionalResponse = Optional("[\n  \"Aircel\",\n  \"Airtel\",\n  \"BSNL\",\n  \"Idea MTV\",\n  \"MTNL\",\n  \"MTS\",\n  \"Reliance CDMA\",\n  \"Reliance GSM\",\n  \"Reliance JIO\",\n  \"TATA CDMA\",\n  \"TATA DOCOMO\",\n  \"Telenor\",\n  \"Videocon\",\n  \"Vodafone\"\n]")
if var response = optionalResponse {
    let charsToRemove = ["\n", "\"", "\\", "[", "]", " "]
    for char in charsToRemove {
        response = response.replacingOccurrences(of: char, with: "")
    }
    let fullNameArr = response.characters.split{$0 == ","}.map(String.init)

    print(fullNameArr)
}

Answer 2

if let dataa = data as? String{
                if let dataFromString = dataa.data(using: String.Encoding.utf8, allowLossyConversion: false) {
                    let json = JSON(data: dataFromString)
                    for (_, val) in json {
                        self.mobileOprator.append(val.rawString()!)
                    }
                }
            }

通过这种方式，我得到了我想要的数组，使用 SwiftyJSON 进行解析..

我如何解析这个respose到我的字符串数组
