I’m working on a view right now that I want to be able to cross compile as either an NSView for the Mac, or a UIVIew for the iPhone. I originally wrote it for Leopard, but now I’m trying to add the precompiler directives to let it cross compile between the two platforms. A quick Google search didn’t reveal anything, here are the possible definitions you can use:

#define __MAC_10_0      1000
#define __MAC_10_1      1010
#define __MAC_10_2      1020
#define __MAC_10_3      1030
#define __MAC_10_4      1040
#define __MAC_10_5      1050
#define __MAC_10_6      1060
#define __MAC_NA        9999   /* not available */

#define __IPHONE_2_0     20000
#define __IPHONE_2_1     20100
#define __IPHONE_2_2     20200
#define __IPHONE_3_0     30000
#define __IPHONE_NA      99999  /* not available */

This definition comes from Availability.h located at /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk/usr/include/Availability.h (for the iPhone 3.0 SDK).

Obviously, the __MAC_10_x is actually for the version of OSX, and the __IPHONE_x_x is for iPhone.

So, if you wanted to have code conditionally compile for the iPhone (assuming 3.0 SDK) you would do something like the following:

#ifdef __IPHONE_3_0
    // iPhone
    #import <UIKit/UIKit.h>
#else
    // Mac
    #import <Cocoa/Cocoa.h>
#endif
