I've got an iOS application project that records audio and then emails the audio via Mail application. However, I want to modify the project to upload the audio file to my Oxwall site via File Uploader (which I have installed). My site features the standard Oxwall login as well as Facebook connect. My site can be found here:

http://Krackl.it

So I need the iOS app to manage login via Facebook or Oxwall as well as sign-up if the user has no account. 

Additionally, I want the user to be able to perform a file upload of the recorded audio via the File Upload page.

I've spoken with a developer on Odesk and he believes that this cannot be accomplished by merely navigating the app to the appropriate webpages on my Owall site. He thinks that there must be some back-end development performed to authenticate users and send a file to the site.

Any opinions regarding this?

Thanks,

Tom
