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
