#if check (preprocessor macro) to differentiate between iPhone and iPad

Question

Is there a build preprocessor macro I can check, with #if or #ifdef to determine if my current Xcode project is being built for iPhone or iPad?

Answer 1

Updation for swift:

Couldn't use preprocessor. Make global function as

func IS_IPAD() -> Bool { 
( return (UIDevice.respondsToSelector(Selector("userInterfaceIdiom"))) && (UIDevice.currentDevice().userInterfaceIdiom == UIUserInterfaceIdiom.Pad) )}
