Answer 1

Only Objective-C is allowed by now... but since a few months ago you are allowed to write scripts that will be interpreted in your application.

So you may be able to write a LUA interpreter or a Python interpreter, then write some part of your application in this scripting language. If you want your application accepted on the App Store, these scripts have to be bundled with the application (your application cannot download it from the Internet for example)
