objective c - Get xcode 4.5 to warn about new API calls

Question

The answer to this question does not appear to work on xcode 4.5. To summarise it, is there a way for XCode to warn about classes, methods and procedures that are only available a later version than the deployment target?

Answer 1

There is a correct answer inside of the question that you linked too. With some experimentation, I came up with this (from mattjgalloway's answer):

#define __AVAILABILITY_TOO_NEW __attribute__((deprecated("TOO NEW!"))) __attribute__((weak_import))

#if __IPHONE_OS_VERSION_MIN_REQUIRED < __IPHONE_6_0
#undef __AVAILABILITY_INTERNAL__IPHONE_6_0
#define __AVAILABILITY_INTERNAL__IPHONE_6_0 __AVAILABILITY_TOO_NEW
#endif

Then repeat for all the versions that make sense (i.e. 4.3 and above for Xcode 4.5). The __IPHONE_OS_VERSION_MIN_REQUIRED macro will check the deployment target.
