查找私有 API 调用 _terminateWithStatus

Question

我刚刚收到一封来自 Apple 的电子邮件，指出我的应用程序因 _terminateWithStatus 的调用而被拒绝。我的应用程序中有一些框架，我相信这可能是罪魁祸首。

我已经运行了 otool 这是我的输出

/usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.3)
/System/Library/Frameworks/Foundation.framework/Foundation (compatibility version 300.0.0, current version 751.49.0)
/System/Library/Frameworks/UIKit.framework/UIKit (compatibility version 1.0.0, current version 1400.0.0)

/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 150.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.4.0)
/usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 227.0.0)
/System/Library/Frameworks/CoreFoundation.framework/CoreFoundation (compatibility version 150.0.0, current version 550.52.0)

我还通过 App Scanner 运行了应用程序，但未显示 TerminateWithStatus在输出中。

谁能指出我找到这个的正确方向？我还看到一些关于使用 nm 和 grep 来查找调用的讨论。提前致谢。

已解决：

深入到构建目录后：

AppName/build/AppName.build/Release-iphoneos/AppName.build/Objects-normal/armv6/ 

我运行：

strings AppName | grep 'terminateWithStatus'

并返回一个结果。经过一番挖掘，我发现测试框架 GHUnit 正在发起调用。我删除了框架，重新构建，然后再次运行字符串命令，但没有任何结果。

我希望这可以帮助任何其他搜索私有 API 调用的人，这并不是一次有趣的冒险。

您必须在可执行文件上运行 otool，而不是在应用程序包装器上运行。

例如（很抱歉格式奇怪）：

$ otool -L WriteRoom.app/Contents/MacOS/WriteRoom 

WriteRoom.app/Contents/MacOS/WriteRoom (architecture ppc):
    @executable_path/../Frameworks/Blocks.framework/Versions/A/Blocks (compatibility version 1.0.0, current version 1.0.0)
    /System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa (compatibility version 1.0.0, current version 11.0.0)
    /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.3.3)
