获取X code 5至警告新的API调用 [英] Get Xcode 5 to warn about new API calls

问题描述

有是一个方法<一href=\"http://stackoverflow.com/questions/12632834/get-x$c$c-4-5-to-warn-about-new-api-calls/12633309\">X$c$c 4.x的：

#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

但由于iOS的7 SDK可用性宏已经改变，现在有更多的差异和选项不起作用了：

But that doesn't work anymore because the iOS 7 SDK Availability macros have changed and now have more variances and options:

6的iOS SDK的AvailabilityInternal.h：

iOS 6 SDK's AvailabilityInternal.h:

#define __AVAILABILITY_INTERNAL__IPHONE_6_0                    __attribute__((availability(ios,introduced=6.0)))
#define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_6_0    __attribute__((availability(ios,introduced=6.0,deprecated=6.0)))
#define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_6_1    __attribute__((availability(ios,introduced=6.0,deprecated=6.1)))
#define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_NA     __attribute__((availability(ios,introduced=6.0)))

的iOS 7 SDK：

iOS 7 SDK:

#define __AVAILABILITY_INTERNAL__IPHONE_6_0                    __attribute__((availability(ios,introduced=6.0)))
#define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_6_0    __attribute__((availability(ios,introduced=6.0,deprecated=6.0)))
#if __has_feature(attribute_availability_with_message)
     #define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_6_0_MSG(_msg)    __attribute__((availability(ios,introduced=6.0,deprecated=6.0,message=_msg)))
#else
     #define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_6_0_MSG(_msg)    __attribute__((availability(ios,introduced=6.0,deprecated=6.0)))
#endif
#define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_6_1    __attribute__((availability(ios,introduced=6.0,deprecated=6.1)))
#if __has_feature(attribute_availability_with_message)
     #define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_6_1_MSG(_msg)    __attribute__((availability(ios,introduced=6.0,deprecated=6.1,message=_msg)))
#else
     #define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_6_1_MSG(_msg)    __attribute__((availability(ios,introduced=6.0,deprecated=6.1)))
#endif
#define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_7_0    __attribute__((availability(ios,introduced=6.0,deprecated=7.0)))
#if __has_feature(attribute_availability_with_message)
     #define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_7_0_MSG(_msg)    __attribute__((availability(ios,introduced=6.0,deprecated=7.0,message=_msg)))
#else
     #define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_7_0_MSG(_msg)    __attribute__((availability(ios,introduced=6.0,deprecated=7.0)))
#endif
#define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_NA               __attribute__((availability(ios,introduced=6.0)))
#define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_NA_MSG(_msg)     __attribute__((availability(ios,introduced=6.0)))

难道X code 5具有 attribute_availability_with_message 功能，使老宏重新定义不再使用？

Could it be that Xcode 5 has the attribute_availability_with_message feature so the old macro redefinition is no longer used?

此外，它会很酷打印不是更太新了！消息与所有新推出/德precated信息。

Also it would be cool to print more than the "TOO NEW!" message with all the new introduced/deprecated information.

编辑：

在iOS的7定义大多SDK从移动__ OSX_AVAILABLE_STARTING（_ios） / __ AVAILABILITY_INTERNAL ## _ IOS 到 NS_AVAILABLE_IOS（_ios） / CF_AVAILABLE_IOS（_ios），所以重新定义：

Most definitions in iOS 7 SDK moved from __OSX_AVAILABLE_STARTING(_ios)/__AVAILABILITY_INTERNAL##_ios to NS_AVAILABLE_IOS(_ios)/CF_AVAILABLE_IOS(_ios), so redefining:

#undef NS_AVAILABLE_IOS
#define NS_AVAILABLE_IOS(_ios) __attribute__((availability(ios,__NSi_##_ios))) __attribute__((deprecated("TOO NEW!")))

应该工作。而实际上它确实是因为X code 5自动完成显示的方法作为德precated。

Should work. And actually it does because Xcode 5 autocompletion shows the methods as deprecated.

不过大厦不会触发任何警告，尽管具有 GCC_WARN_ABOUT_DE preCATED_FUNCTIONS 基础上...选项

Building however doesn't trigger any warning despite having the GCC_WARN_ABOUT_DEPRECATED_FUNCTIONS build option on...

推荐答案

为x code 5.0，不可能通过重新定义宏来获得新的API调用的警告。

As of Xcode 5.0 it is not possible to get warnings from new API calls by redefining macros.

重新定义一个宏并在自动完成和preprocessed preVIEW（助理编辑> preprocess）出现，但尽管使用德precate 或不可用关键字。

Redefining a macro does show up in autocompletion and preprocessed preview (Assistant Editor > Preprocess) but does not trigger a warning despite using deprecate or unavailable keywords.

X $ C $ç5.0.1+确实显示警告这样既 __ AVAILABILITY_INTERNAL__IPHONE_X_X 和 NS_AVAILABLE_IOS ，现在可以重新定义为在问题和@borrrden答复中提到。

Xcode 5.0.1+ does show a warning so both __AVAILABILITY_INTERNAL__IPHONE_X_X and NS_AVAILABLE_IOS can now be redefined as mentioned in the question and @borrrden answer.

code可作为吉斯特并作为的库：

Code available as a Gist and as a library:

#endif

#if __IPHONE_OS_VERSION_SOFT_MAX_REQUIRED < __IPHONE_OS_VERSION_MIN_REQUIRED
    #error You cannot ask for a soft max version which is less than the deployment target
#endif

#define __NBU_AVAILABILITY_STARTING(version) __attribute__((deprecated("Only available in iOS " version "+"))) __attribute__((weak_import))
