(Objective-C) Twilio Send MMS (using Chilkat HTTP)

Send an outgoing MMS message. The only difference with MMS (as compared with SMS) is that a MediaUrl parameter is added to the POST. This means your image must be accessible on the web -- the Twilio server must be able to download the image from the URL you provide to include it in the MMS mesage to be sent.

Also, see Twilio MMS for more information about MMS.
