I was looking at Apple's Lister (for Apple Watch, iOS, and OS X) sample. The sample performs a test for iOS and OS X:
#import <TargetConditionals.h>
#if (TARGET_OS_IPHONE || TARGET_IPHONE_SIMULATOR)
@import ListerKit;
#elif TARGET_OS_MAC
@import ListerKitOSX;
#endif
However, there is no test for TARGET_OS_WATCH
or similar. Grepping for watch
in TargetConditionals.h
delivers no hits:
$ cat /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer
/SDKs/iPhoneOS7.1.sdk/usr/include/TargetConditionals.h | grep -i watch
$
From TargetConditionals.h
, I know there are:
These conditionals specify in which Operating System the generated code will run. The MAC/WIN32/UNIX conditionals are mutually exclusive. The EMBEDDED/IPHONE conditionals are variants of TARGET_OS_MAC. TARGET_OS_MAC - Generate code will run under Mac OS TARGET_OS_WIN32 - Generate code will run under 32-bit Windows TARGET_OS_UNIX - Generate code will run under some non Mac OS X unix TARGET_OS_EMBEDDED - Generate code will run under an embedded OS variant of TARGET_OS_MAC TARGET_OS_IPHONE - Generate code will run under iPhone OS which is a variant of TARGET_OS_MAC. TARGET_IPHONE_SIMULATOR - Generate code for running under iPhone Simulator
Question: Is there a preprocessor for Apple's watch?
I'm tagging with ios, but I'm not sure that's the correct OS for this question.
The list below was compiled from iPhone's TargetConditionals.h
. The Simulator and OS X are similar (they just have different bits set to 1):
#define TARGET_OS_MAC 1
#define TARGET_OS_WIN32 0
#define TARGET_OS_UNIX 0
#define TARGET_OS_EMBEDDED 1
#define TARGET_OS_IPHONE 1
#define TARGET_IPHONE_SIMULATOR 0
Questions: Does the watch use TARGET_OS_EMBEDDED
? Does the watch omit TARGET_OS_IPHONE
?
As of watchOS 2.0, you can run native code on the watch, so this is a more relevant question.
I'm using the first early beta of watchOS 2, so this may change, but right now, TARGET_OS_WATCH
is set to 1 on watchOS.
(Also, be careful: TARGET_OS_IPHONE
is also set to 1 on watchOS, though TARGET_OS_IOS
is 0.)
