    "responsetime": "dd/mm/yyyy hh:mm:ss",
    "location": null,
    "surveyresponses": [
        {
            "questionid": "111",
            "responses": [
                {
                    "response": "Good",
                    "optionid": 1,
                    "language": "en"

i totally agree with @Apurv, actually @Paras Joshi give the actual answer to your question...(how to send)

NSMutableDictionary *dict = [[NSMutableDictionary alloc]init];
[dict setValue:@"Survey1" forKey:@"surveyid"];
[dict setValue:@"responsetime" forKey:@"dd/mm/yyyy hh:mm:ss"];
.
.
.

and then an array forKey @"surveyresponses"... in it again create a dictionary...bla..bla

Please make it clear first what you exactly want... How to send a JSON string / how to generate a JSON value.
