iOS: Using JSONModel, how do you grab dictionaries with numeric key?

I'm currently using JSONModel by icanzilb to parse my JSON structures obtained online. The issue is that I have a dictionary which has numeric keys, plus these numeric keys are generated by the server on-demand. So theoretically I have no advance knowledge of what these numeric keys will be. So under this situation, I couldn't add a @property to my JSON data header files.

Any idea on how to deal with this situation?

An example of the JSON structure:

{
 "Content":[
             {
              "0":{...},
              "1":{...},
              "2":{...},
              "Forum":"1",
              "Member": "Michael",
             }
          ],
 "Count":"5"
}
