为什么在目标c中以json格式推送通知显示？我想要字符串格式？

Question

Json格式：

{aps ={alert="{\"NotificationTypeId\":3,\"Message\":\"   
    {\\\”User_Id\\\":1,\\\"PollsQuestion_Id\\\":186,\\\"PollQuestion\\\":
    \\ \"HELLO ANSWER THIS  POLL\\\",\\\"polloptionsdetails\\\":  
    [{\\\"Pollsoptio";badge = 3;sound = "sound.caf";};}

谢谢。
