I wrote an iPhone app. Then, I changed the interface a fair bit, added higher res images, and made an iPad version of it. In a perfect world, I would like for anyone who buys the iPad version to get the iPhone version for free (though not conversely). Since Apple doesn’t seem to have a way to do that (right??), my next favorite solution is to make the iPad version include the iPhone version somehow.

I know that I could just convert the iPad version to “universal”, but since the face of the app is so different, that seems like a real pain. I have many view controllers and they are almost completely different between the two versions. Some of the methods are the same, but only about 30%. Is there an easy solution along the lines of this:

  • Check if device is iPhone or iPad

    • If iPhone, then use one group of files

    • If iPad, then use a different group of files

Thanks in advance!

    Try creating a new project in Xcode and choose to make it a universal app. In the default way Xcode lays it out, there is a distinct divide between the iPad and iPhone versions. You can make the two versions of the app as similar or different as you want.

    In addition, you can check which device you are running on at runtime by using UI_USER_INTERFACE_IDIOM(). Currently the two values for this are UIUserInterfaceIdiomPad and UIUserInterfaceIdiomPhone.
