它包含一个包含2个字段的json对象：MsgType和Msg。 Msg进一步包含字符串形式的序列化json对象。

我需要将MsgType的值读作数字，将Msg作为json对象读取。

我尝试了几件事：

首先：

  if let dataFromString = text2.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false) {
                                let json = JSON(data: dataFromString)
                                print("swiftyjson:\(json)")
                            }

来源：https://github.com/SwiftyJSON/SwiftyJSON#initialization

输出：

swiftyjson：空

其次：

let data = text2.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!

                            do {
                                let jsonSys = try NSJSONSerialization.JSONObjectWithData(data, options: [])
                                print("jsonSys:\(jsonSys)")
                            } catch let error as NSError {
                                print("Failed to load: \(error.localizedDescription)")
                            }

输出：

无法加载：无法读取数据，因为它不在格式正确。

Answer 1

您的JSON字符串未正确转义。

＆＃34; Msg＆＃34;开头字典{不应该以双引号开头，它应该是这样的：

＆＃34; {\＆＃34; MSGTYPE \＆＃34;：103，\＆＃34;消息\＆＃34;：{\＆＃34; UserObject \＆＃34; ...

最后相同的错误，应该是：

... 77.1258，\＆＃34; ContactType \＆＃34;：\＆＃34; \＆＃34;}]}}＆＃34;

无法将字符串转换为Json对象
