推荐答案

我完全同意@Apurv，
其实@Paras Joshi给你的实际答案问题...（如何发送）

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"];
.
.
.

然后数组 forKey @surveyresponses ...再次创建一个字典... bla..bla

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

请先说清楚你最想要的...如何发送一个JSON字符串/如何生成JSON值。
