Upload image with status


Hi all,
i have OAUTH operational, and i can upload an image using https://api.twitter.com/1.1/statuses/update_with_media.json.
I am trying to upload an image WITH a status update. As far as i can tell, i need to use https://api.twitter.com/1.1/statuses/update.json, since the original call has been deprecated.
i cannot for the life of me find an Objective-C example of how to do this.
I do not want to use a 3rd party library, since this is ALL i need to do, and since i have the original already operational, i figure it SHOULD be trivial to get this operational if i can get a code snippet.
Can anyone share some information here?
