How do you do it? I saw one video tutorial on it, but the screen was too small. Also, other than changing the view size, are there any other major changes I would have to
In XCode 4.3.2, the easiest way for me to create iPad version of xib is duplicating that xib file and add ~ipad
suffix to the filename. And add both "myVC.xib" and "myVC~ipad.xib" into your project. Note that it is "~ipad" NOT "~iPad". Your app will use that ~ipad version automatically when run on iPad. This also works with resource files (e.g. images).
