NSString converted to Nsdictionary

If there is a string in JSON format

NSString *jsonstr =@"{  "Api": "Ccf.cart2.queryPointsBalance",  "Code":"1",  "v":"1.0",  "msg":"",  "Data": {    "totalbalancequantity":"4",    "Totalbalanceamt":"0.04",    "Errorinfos": {      "ErrorCode":"",      "errormessage":""    }  }}";

Direct conversions are problematic and must be escaped first (you can go to the JSON site). Written

@" {\"api\": \ "ccf.cart2.querypointsbalance\", \ "code\": \ "1\", \ "v\": \ "1.0\", \ "Msg\" : \ "\", \ "data\": {\ "totalbalancequantity\": \ "4\", \ "totalbalanceamt\": \ "0.04\", \ "Errorinfos\": {\ "errorcode\": \ "\" , \ "errormessage\": \ "\"}}"*data =*tempdictquerydiamond = [nsjsonserialization Jsonobjectwithdata:data options:0 Error:nil];

The Tempdictquerydiamond is then printed as

{API="ccf.cart2.queryPointsBalance"; Code=1; Data={Errorinfos={ErrorCode=""; ErrorMessage="";        }; Totalbalanceamt="0.04"; Totalbalancequantity=4;    }; Msg=""; V="1.0";}
