如何将仅iPad的应用程序转换为通用应用程序？

Question

I recently wrote an iPad app that I would like to make a universal app.

What is the best way to do this? Can I simply create two versions of my XIB files and load the appropriate XIB based upon the device?

Answer 1

This should help you out a lot: http://iphonedevelopment.blogspot.com/2010/04/converting-iphone-apps-to-universal.html

Yes, you can create 2 xib files for every screen (one for iPad, and one for iPhone/iPod).

Answer 2

Yes, you do need 2 .xib files for every screen. The tutorial that NeilMonday posted is helpful, but I found this one to be better: http://www.raywenderlich.com/1111/how-to-port-an-iphone-application-to-the-ipad
