Swift开发：使用SwiftyJSON解析JSON数据

1 下载配置SwiftyJSON

GitHub地址：https://github.com/SwiftyJSON/SwiftyJSON

使用配置：直接将 SwiftyJSON.swift添加到项目中即 

2 解析案例文件

 demo.json 放置项目中，json内容如下

3 开始解析

  只有部分解析，其他解析结合demo.json就知道怎么解析了

override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        
        let path = Bundle.main.path(forResource: "demo", ofType: "json");
        
        let jsonData = NSData(contentsOfFile: path!);
        
        do{
            
            let json = try JSON(data: jsonData! as Data);
            
            //system
            let system_array = json["system"];
            print("id: \((system_array["id"].int)!)");
            print("model: \((system_array["model"].string)!)");
            
            //info
            let info_array = json["info"];
            
            // info sync
            print("sync: \((info_array["Sync"].bool)!)");
            
            
            //info port
            let info_port_array = info_array["port"];
            
            for i in 0..<info_port_array.count {
                let io = info_port_array[i]["io"].int!;
                print("io:\(io)");
            }
            
        }
        catch{
            print("error ");
        }
    }
