iOS で mapquest ジオコード json を解析しようとしていますが、NSJSONSterilization は null を返します。オンラインの json チェッカーで確認したところ、URL は実際には json のようです。

ここにコードがありますNSJSONSerialization

 if(geocodeResponseData)
 {
     NSLog(@"there is response data");
     //this is logged.
 }


 NSDictionary *mapQuestReponse =  [NSJSONSerialization
                                     JSONObjectWithData:geocodeResponseData
                                     options:kNilOptions
                                     error:&error];

 NSLog(@"mapquestreponse %@", mapQuestReponse);

これは、JSON解析のために返される URL です。

rederBatch で結果を取得しています。URL からそれを削除する必要があります。次の URL を使用してください。

同じ NSJSONSerilization を使用して解析できるようになりました。
