You would probably have to use Availability.h and something like...
#ifdef __MAC_OS_X_VERSION_MIN_REQUIRED
// code only compiled when targeting Mac OS X and not iPhone
// note use of 1070 instead of __MAC_10_7
#if __MAC_OS_X_VERSION_MIN_REQUIRED == 1070
// code in here to run targeting Lion
#else
// code here can assume targeting pre- or post-Lion.
#endif
#endif
