這個NSString數據類型的字符串如何轉換成一個NSArry數組？在安卓中是通過getJSONbject("Android")解析出來的

最佳回答：

最後輸出的就是NSArray

         let data = jsonString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
        if data != nil {
            let obj: AnyObject? =  NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers, error: nil)
            if obj!.isKindOfClass(NSArray.classForCoder()) {
                print(obj)
            }

        }
