No...you originally write in Objective-C, using an Objective-C framework designed to make cross-compiling to Flash bytecode easier. I think Apple would be a-ok with its competing platforms getting filled with ported apps. You'll still need to program in Objective-C though, and it's hard to see what advantage Adobe's existing apps would bring to Objective-C development.
It's pretty simple for Apple to get around. They can wait until someone does something like this, and then go update their agreement to say cross-platform ui toolkits are not allowed to be used.
