They enable function prototypes and Objective-C methods to be tagged with the OS version in which they were first available; and, if applicable, the OS version in which they became deprecated. The desktop Mac OS X and iOS each have different version numbers. The __OSX_AVAILABLE_STARTING() macro allows you to specify both the desktop and iOS version numbers. For instance: __OSX_AVAILABLE_STARTING(__MAC_10_2,__IPHONE_2_0) means the function/method was first available on Mac OS X 10.2 on the desktop and first available in iOS 2.0 on the iPhone. If a function is available on one platform, but not the other a _NA (not applicable) parameter is used. For instance: __OSX_AVAILABLE_STARTING(__MAC_10_3,__IPHONE_NA) means that the function/method was first available on Mac OS X 10.3, and it currently not implemented on the iPhone.
At some point, a function/method may be deprecated. That means Apple recommends applications stop using the function, either because there is a better replacement or the functionality is being phased out. Deprecated functions/methods can be tagged with a __OSX_AVAILABLE_BUT_DEPRECATED() macro which specifies the OS version where the function became available as well as the OS version in which it became deprecated. For instance: __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_10_0,__MAC_10_5,__IPHONE_NA,__IPHONE_NA) means that the function/method was introduced in Mac OS X 10.0, then became deprecated beginning in Mac OS X 10.5. On iOS the function has never been available. For these macros to function properly, a program must specify the OS version range it is targeting. The min OS version is specified as an option to the compiler: -mmacosx-version-min=10.x when building for Mac OS X, and -miphoneos-version-min=y.z when building for the iPhone. The upper bound for the OS version is rarely needed, but it can be set on the command line via: -D__MAC_OS_X_VERSION_MAX_ALLOWED=10x0 for Mac OS X and __IPHONE_OS_VERSION_MAX_ALLOWED = y0z00 for iOS. Examples:
A function available in Mac OS X 10.5 and later, but not on the phone: extern void mymacfunc() __OSX_AVAILABLE_STARTING(__MAC_10_5,__IPHONE_NA);
An Objective-C method in Mac OS X 10.5 and later, but not on the phone: @interface MyClass : NSObject -(void) mymacmethod __OSX_AVAILABLE_STARTING(__MAC_10_5,__IPHONE_NA); @end
An enum available on the phone, but not available on Mac OS X: #if __IPHONE_OS_VERSION_MIN_REQUIRED enum { myEnum = 1 }; #endif Note: this works when targeting the Mac OS X platform because __IPHONE_OS_VERSION_MIN_REQUIRED is undefined which evaluates to zero.
An enum with values added in different iPhoneOS versions: enum { myX = 1, // Usable on iPhoneOS 2.1 and later myY = 2, // Usable on iPhoneOS 3.0 and later myZ = 3, // Usable on iPhoneOS 3.0 and later ... Note: you do not want to use #if with enumeration values when a client needs to see all values at compile time and use runtime logic to only use the viable values.
It is also possible to use the *_VERSION_MIN_REQUIRED in source code to make one source base that can be compiled to target a range of OS versions. It is best to not use the _MAC_* and __IPHONE_* macros for comparisons, but rather their values. That is because you might get compiled on an old OS that does not define a later OS version macro, and in the C preprocessor undefined values evaluate to zero in expresssions, which could cause the #if expression to evaluate in an unexpected way. #ifdef __MAC_OS_X_VERSION_MIN_REQUIRED // code only compiled when targeting Mac OS X and not iPhone // note use of 1050 instead of __MAC_10_5 #if __MAC_OS_X_VERSION_MIN_REQUIRED < 1050 // code in here might run on pre-Leopard OS #else // code here can assume Leopard or later #endif #endif

/* * __API_TO_BE_DEPRECATED is used as a version number in API that will be deprecated * in an upcoming release.
