objectiveC中创建JSON字符串

Question

需要动态生成json字符串然后发送到服务器，不知道应该怎么实现？

使用了NSJSONSerialization。

下面就是字符串：

{
    "surveyid": "Survey1",
    "responsetime": "dd/mm/yyyy hh:mm:ss",
    "location": null,
    "surveyresponses": [
        {
            "questionid": "111",
            "responses": [
                {
                    "response": "Good",
                    "optionid": 1,
                    "language": "en"
                }
            ]
        },
        {
            "questionid": "112",
            "responses": [
                {
                    "response": "bad",
                    "optionid": 2,
                    "language": "en"
                }
            ]
        }

    ]
}

创建一个string.json，请高手帮忙啊。谢谢

将Json转化为JsonString，将其放在NSData里面，通过ASIDataFormRequest setPostValue： forKey：，发送到服务器即可
