Question

If I want to target all iOS devices version 4.3 or later, I can use:

#if __IPHONE_OS_VERSION_MIN_REQUIRED >= __IPHONE_4_3

Also, if I want to target iOS devices in general, I can use:

#if TARGET_OS_IPHONE

Is there something similar for Mac OS X?

Answer 1

NSAppKitVersionNumber is your friend on OS X. To target eg. 10.5 and upwards, you can do this:

#if NSAppKitVersionNumber >= NSAppKitVersionNumber10_5

// ...

#endif

Edit: Just seen that there are also __MAC_OS_X_VERSION_MAX_ALLOWED and __MAC_OS_X_VERSION_MIN_REQUIRED on OS X, which might work better and which are available in the Availability.h which is not Cocoa dependent.
