Are we running on an Apple platform?

#ifdef __APPLE__

…

#endif

Prerequisite for other tests

#ifdef __APPLE__
// let Apple define
// various TARGET_OS_
// constants

#include
#else
// not on Apple platform
#define TARGET_OS_MAC 0
#define TARGET_OS_IPHONE 0

#endif

Are we running on Mac OS X?

#if TARGET_OS_MAC && !TARGET_OS_IPHONE

….

#endif

Are we running on an iOS device?

#if TARGET_OS_IPHONE

….

#endif

// updated on Oct13 2010, previous method was flawed. sorry everyone!
