Can I use one class category extension .h and .m file for iOS and OSX?

Is there a way to have one header and implementation file for both OSX categories and iOS categories? I don't want to make the methods the exact same and add another two files.

I've tried this, which doesn't work:

#if TARGET_OS_IPHONE
#define kClass [UIColor class]
#import <UIKit/UIKit.h>
#elif TARGET_OS_MAC
#define kClass [NSColor class]
#import <AppKit/AppKit.h>
#endif

@interface kClass (MyCategory)

Is there a way to do this?

Absolutely! Just remember that #define is a simple text replacement before compilation: you want kClass to be UIColor, not [UIColor class], just as you would never write @interface [UIColor class] (MyCategory).

In conclusion:

#if TARGET_OS_IPHONE
#define kClass UIColor
#import <UIKit/UIKit.h>
#elif TARGET_OS_MAC
#define kClass NSColor
#import <AppKit/AppKit.h>
#endif

@interface kClass (MyCategory)
