QuickLook PlugIn是"损坏/缺少资源".为什么？

Question

设置:
OS X 10.8.2
Xcode4.5.2(4G2008a)
基于文档的Cocoa应用程序,带有QuickLook插件

---

问题:

我正在尝试将QuickLook插件添加到基于Document的OS X应用程序中,但QL PlugIn将无法启动.

我的QuickLook PlugIn需要嵌入并链接到我自己创建的两个框架(Called IDEKit和TDAppKit).我已经阅读了这篇关于在QuickLook PlugIns中链接Frameworks的帖子,并按照那里的说明(我将DYLIB_INSTALL_NAME_BASE我的两个框架设置为@loader_path/../Frameworks).

以下是有关我的QuickLook PlugIn构建后的一些相关信息:

但是,当我尝试使用qlmanage和测试文档启动我的QuickLook PlugIn时,我收到以下错误:

dyld: DYLD_ environment variables being ignored because main executable (/System/Library/Frameworks/QuickLook.framework/Versions/A/Resources/quicklookd.app/Contents/MacOS/qlmanage) is code signed with entitlements
Testing Quick Look preview with files:
    /Users/itod/Desktop/test.shapes

注意:

The bundle “ShapesQuickLook” couldn’t be loaded because it is damaged or missing necessary resources.

我不确定这个问题是由嵌入式框架的问题引起的(但我认为可能是这样).

我可能会失踪什么？如何启动QuickLook PlugIn？

Answer 1

OP在这里.我在这篇博客文章中找到了关于Dylibs,Install Names和rpaths的解决方案.

具体来说,@rpath部分的建议对我有用.

所以在我的嵌入式框架中,我设置DYLIB_INSTALL_NAME_BASE为@rpath/.

然后我有一个App和一个Q​​L PlugIn,每个都嵌入了框架:

在我的应用程序目标的构建设置中,我添加了以下其他链接器标志:-rpath @executable_path/../Frameworks/.

在我的QuickLook插件目标的构建设置中,我添加了以下其他链接器标志:-rpath @loader_path/../Frameworks/.

这解决了这个问题.现在应用程序和QL PlugIn正常工作.
