I've developed a couple dozen iPhone apps, several in the App store. Now I'd like to port a few of them to run on a Mac without the Simulator environment. How much work would it be to port the source of a basic iPhone UIKit app so that it runs natively on a Mac? Are app delegates, text views, buttons, Core Graphics, audio queues, etc. mostly the same between the iPhone UIKit and the Mac Cocoa frameworks? Or will significant rewrites be required in these areas? What's the minimum new code that has to be added? I assume at least an outlet to handle a "Quit" menu item. Anything else necessary? Thanks.
