I don’t Know
You will need a Mac with xCode and a dev account from apple. You then long press on the project and select export to xCode. Load it into xcode then add anything you need to. I’ve never submitted to the App Store but from there I believe you can build and submit.
There is a tutorial on how to do this here: http://codeatuts.blogspot.com.au/2013/04/tutorial-27-codea-v152-export-to-xcode.html
