Twilio developer evangelist here.

You seem to be using the old, deprecated Sms resource which doesn't support MMS. You really want to be using the Messages resource which does work.

On a separate note, I would not recommend making API calls directly to Twilio from your iOS application (or any other client application). To do this you would need to embed your Twilio credentials within the application which is dangerous. I would recommend sending the SMS/MMS from a server side application as in this example.
