Answer 1

In XCode, go into the Project menu, and select “Upgrade Current Target for iPad”. Choose the “Universal App” option. This will upgrade your target without changing any code at all. Open up the new iPad nib files, make sure everything looks good, and you should be good to go.

(EDIT: you’ll need to manually upgrade each of your nib files, and resize and prepare them for the iPad version.)

That said, the odds are that to make things look perfect, you’ll need to write some iPad code. To make this happen, create a file called CommonMacros.h and add:

#ifndef __IPHONE_3_2    // if iPhoneOS is 3.2 or greater then __IPHONE_3_2 will be defined

typedef enum {
    UIUserInterfaceIdiomPhone,           // iPhone and iPod touch style UI
    UIUserInterfaceIdiomPad,             // iPad style UI
} UIUserInterfaceIdiom;

#define UI_USER_INTERFACE_IDIOM() UIUserInterfaceIdiomPhone

#endif // ifndef __IPHONE_3_2

Now, if you want to branch your code between iPhone and iPad, just add

#import "CommonMacros.h"

to the top of your .m file. Then, anywhere in your code, you can use this method:

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
    // iPad code here
} else {
    // iPhone / iPod code here
}

One example of where you’d do this would be if you wanted to add some extra graphical element to the iPad version, or didn’t want the iPad version to have access to some iPhone feature.
