QuickLook PlugIn是“受损/缺失的资源”。为什么？

Question

设置：

OS X 10.8.2

Xcode4.5.2 (4G2008a)

基于文档的QuickLook PlugIn Cocoa应用程序

​

问题：

​

我试图在我的基于文档的OS应用程序中添加一个QuickLook插件，但是QL plugin不会启动。

我的QuickLook PlugIn需要嵌入并链接到我自己创建的两个框架(称为IDEKit和TDAppKit)。我已经阅读了这个因此，在QuickLook PlugIns中发布关于链接框架的文章，并遵循了这里的说明(我将我的两个框架的DYLIB_INSTALL_NAME_BASE设置为@loader_path/../Frameworks)。

以下是构建后的QuickLook PlugIn的一些相关信息：

已建立了链接/嵌入框架：

但是，当我试图使用QuickLook PlugIn和测试文档启动PlugIn时，会出现以下错误：

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

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)。

我可能错过了什么？我怎样才能启动我的QuickLook PlugIn？

Answer 1

在这里行动。我在这个关于Dylibs、安装名称和rpath的博客文章中找到了解决方案。

具体来说，@rpath部分下的建议对我有用。

因此，在我的嵌入式框架中，我将DYLIB_INSTALL_NAME_BASE设置为@rpath/。

然后我有一个应用程序和一个QL PlugIn，它们都嵌入了框架：

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，我添加了以下链接标记：-rpath @loader_path/../Frameworks/。

解决了这个问题。现在，应用程序和QL PlugIn工作正常。
