如何使用iOS SDK从ASMX Web服务获取和解析JSON？

Question

I have a ASMX - Web Service and wanted to request a result as JSON. Therefore I used Fiddler to send a POST-Request.

Method:

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public List<string> AllProjects()
{
   List<ProjectData> pList = m_linqHelper.GetProjects(string.Empty).ToList();
   List<string> ProjectNames = pList.Select(p => p.ProjectName).ToList();
   return ProjectNames;
}

Fiddler POST-Request:

POST http://localhost:52225/MyWebService.asmx/AllProjects HTTP/1.1
Content-Type: application/json
Host: localhost:52225
Content-Length: 0
Connection: Keep-Alive

As the result I got a string like:

{"d":["My_Project"]}

What bothers me is the "d": . How can I parse such a request using the iOS SDK?

Thanks in advance.

I use ASMX webserices too. For my requests I have implemented the AFNeworking library available on GitHub to call Webservice.

You can find help on the GitHub page. Then, the webservice give me a JSON result. So I convert it like that :

NSDictionary *json = [NSJSONSerialization JSONObjectWithData:responseObject options:0 error:nil];

Where responseObject is the result of AFNetworking request.
