cocoa - 为什么 Sierra 要求联系人 (AddressBook) 权限？

Question

当使用我的应用程序的人们过渡到 Sierra (MacOS 10.12) 时，操作系统突然要求他们授予访问联系人的权限。我不知道为什么要这样做；它不会在任何以前的操作系统上执行此操作。

更重要的是，应用程序无法访问联系人；事实上，我根本没有加载 ABAddresssBook 框架。我已经搜索了地址和联系方式的来源，但没有结果。 Xcode 没有显示“功能”。我使用的唯一第三方框架是 Sparkle。 (我静态链接 mp4v2 库，它对 MacOS 一无所知。)仅供引用，此应用程序作为签名的第三方分发，而不是通过 App Store。它确实有一些嵌入式命令行可执行文件(例如 ffmpeg 等)，同样不是 OS X 特定的。

我尝试使用调试器来查看触发通知的内容。它显示了一个后台线程，其中一个 block 执行以获取 [ABAddressBook sharedAddressBook]，然后启动用户请求，但没有指示谁启动了该 block 。

还有什么建议可以去哪里看吗？

这是应用程序和 Sparkle 的 otool -L 库列表。

原来是 Cocoa Lumberjack 日志框架。其中一种方法要求所有类查看它们是否已启用日志记录，并对日志记录执行“class_getClassMethod”。如果您使用 ABAddressBook 执行此操作，则会触发用户的访问请求。
