[swift] NetWork (4) 解析Json

• 先做一個json檔案來模擬接到時怎麼解析 ```csharp
  {
  “組織名稱”:”普攏拱團隊”,
  “組織成員”:[
  {“姓名”:”科科人”,”年齡”:11},
  {“姓名”:”可可狗”,”年齡”:120}
  ]
  }

*   在viewDidLoad加上,測試看看！！ ```swift
//將檔案讀出來
        let path = NSBundle.mainBundle().pathForResource("json", ofType: "txt");
        var data:NSData = NSData(contentsOfFile: path!)!;
        //解析Json
        var jsonobj = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary;
        println(jsonobj["組織名稱"] as String);
        println("組織成員");
        var arr = jsonobj["組織成員"] as NSArray;
        for i in (0...arr.count - 1){
            let mdic = arr[i] as NSDictionary;
            println(mdic["姓名"] as String);
            println(mdic["年齡"] as Int);
        }
