But it wont be a compatibility layer, it would be no different than using a third party Objective C library. Apple cant really mandate all code for an app be written by the developer team itself. Basically its all Objective C code and some Adobe tool cross compiles it to bytecode that the Flash Player can play
>3.3.1 — Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited).
For the purpose of your post, the important sentence in all that is:
Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited
So nee, your solution of a Objective C library written for android would be a compatibility layer, and therefore is forbidden.
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.
