iOS8 - 无法符号化来自自定义动态框架的符号

Question

这是我的资料： - iOS 名为 VacationSpots 的应用（.APP 文件）

应用程序 dSYM 文件
名为 VSUtilities 的动态框架（.framework 文件）
动态框架dSYM文件

示例项目源代码如下：https://www.dropbox.com/s/nl32xlk98lnl1mv/VacationSpots.zip?dl=0

我通过强制解包一个 nil 可选项使应用程序在启动时崩溃。

以下是符号化崩溃报告的一部分。请注意，VSUtilities 调用未被符号化：

今天遇到了类似的事情。我的案例有两个问题：

.app 内的框架不会获得 "indexed enough"/获取 mdfind 的所有元数据，如 kMDItemDisplayName，除非我将其移出 .app.
symbolicatecrash 将 mdfind 与 "kMDItemContentType == public.unix-executable" 一起使用，而我的框架可执行文件的真实 kMDItemContentType 是 "public.data".

通过以下方式解决：

将 .framework 移出 .app（在我的例子中，我将所有内容都移到了桌面，以确保它能被正确索引）
修改（副本）symbolicatecrash 以不仅查找 "kMDItemContentType == public.unix-executable"，而且查找 "kMDItemContentType == public.data"

P.S。您可以使用 mdls 获取文件的索引元数据属性：

MacBook-Pro-GE:~ eg$ mdls -name kMDItemContentType ~/Desktop/OPASAppKit.framework/OPASAppKit kMDItemContentType = "public.data"

至于 symbolicatecrash 的修改版本，我不确定我是否可以 post 它在这里，但是这里有一个差异，只有一行被改变了。

顺便说一句，看起来 Xcode 也使用 symbolicatecrash 进行符号化，因此在 Xcode 中修补脚本允许我在那里也使用自定义动态框架来符号化崩溃。
