With C++, there is a macro *__cplusplus*. Is there anything analogous for the Objective-C 2.0?


I've used the following test:

#if defined(MAC_OS_X_VERSION_10_5) && (MAC_OS_X_VERSION_10_5 <= MAC_OS_X_VERSION_MIN_REQUIRED) && defined(__APPLE_CC__) && (__APPLE_CC__ >= 5465) ... statements in ObjC2.0 syntax ... #else ... statements in pre-2.0 syntax ... #endif

This is, obviously, very specific to Apple's gcc, but as far as I know there are no other ObjC2 implementations (and within a year or two I won't be trying to support pre-Leopard targets anyway). I agree it would be a good thing if there were an __OBJC_2_0__ macro or similar way for the preprocessor to tell whether the new syntax is usable...
