Answer 1

I know that @indragie's answer is a very common one, but it's a common misunderstanding that will cause you a lot more work than you actually need to do.

As long as you name the xib files a certain way, they will be automatically selected for either iPhone or iPad. Check out my answer to this same problem on another post:

Answer 2

You can use UI_USER_INTERFACE_IDIOM() to check whether the application is running on an iPad or an iPhone/iPod touch:

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
    // Running on iPad
} else {
    // Running on iPhone or iPod touch
}

For more information on loading NIB files, read Apple's Resource Programming Guide on Nib Files. You may want to specifically check out the Loading Nib Files Programmatically section which shows how to programatiically load a NIB from within your code using NSBundle. You can then use this in conjunction with the above code to correctly load the proper NIB depending on which device you're runining on.

Just add a file named MainView~ipad.xib makes it load this one i.s.o. MainView.xib when running on a iPad..
