Universal iPad/iPhone XIBs - Xcode 4

Question

I want to make a universal app which has two different XIB files. One for iPhone, and one for iPad. They use the same code, just different UIs. How would I create a \"universal\

Answer 1

If you have existing app then there is option in Targets-->upgrade for iPad/iPhone

After that add code to check whether application is running in iPad or iPhone.

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
    //load xib of ipad
}
else
{
    //load xib of iphone
}
