获取xcode 4.5以警告新的API调用 [英] Get xcode 4.5 to warn about new API calls

问题描述

这个问题的答案似乎不适用于xcode 4.5。总结一下，XCode是否有办法警告只有比部署目标更高版本的类，方法和程序？

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?

推荐答案

你所链接的问题里面有一个正确的答案。通过一些实验，我想出了这个（来自mattjgalloway的答案）：

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

然后重复所有有意义的版本（即Xcode 4.5的4.3及以上版本）。 __ IPHONE_OS_VERSION_MIN_REQUIRED 宏将检查部署目标。

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.
