我正在尝试使用Xcode中的跨项目引用来创建Cocoa框架。
我有两个项目：一个用于框架;一个用于将使用该框架的应用程序。
此框架不旨在存储在系统中;它是一个嵌入在应用程序包中的嵌入式框架。
我已经成功地进行了跨项目引用，将框架标记为我的目标的依赖项，添加了一个Copy Files构建阶段，该框架将框架放入Contents / Frameworks /并将框架添加到链接器阶段（我检查过）小“目标”复选框;我也通过将框架拖到链接器阶段手动完成。
我的框架的安装目录已正确设置为@executable_path /../ Frameworks。
然而，当我尝试构建我的应用程序时：
a）首先正确构建框架 b）正确复制框架 c）错误，因为它无法在我的框架中找到主头文件
我已经确认标题在那里。我可以在部分构建的应用产品中看到它。
ls build/Debug/CioccolataTest.webapp/Contents/Frameworks/Cioccolata.framework/Headers/Cioccolata.h
build/Debug/CioccolataTest.webapp/Contents/Frameworks/Cioccolata.framework/Headers/Cioccolata.h
我已经能够通过将我的框架复制到/ Library / Frameworks中来成功构建应用程序（我可以在成功构建后再次将其删除），但这是一种解决方法，我希望找到它为什么Xcode在没有将其复制到系统目录的情况下，找不到框架的主头文件。在构建期间将它复制到应用程序包是不够的？
这是完整的构建脚本，如果它有任何帮助（它现在只是一个Hello World应用程序，所以这里没有多少）：

我知道这篇文章现在已经过时了，但是我正在研究另一个项目，并且对于在构建这个项目之前必须从一个单独的项目构建的嵌入式框架设置另一个跨项目引用感到不满。
这次我提出了一个更优雅的修复（可能是“正确的”修复），基本上是因为我上次做的不起作用（Xcode一直在抱怨它无法找到框架的主头文件）。
解决方案。我刚从头开始测试了很多项目，以确保......
虽然它看起来很啰嗦，但大多数情况都很正常，而且如果依赖目标在同一个项目中，那么你正在做什么。然而，关键的第一个构建阶段需要将构建的产品从另一个项目复制到当前项目的构建目录中。
显然，Xcode非常聪明，可以让其他项目执行构建，但是当它开始编译依赖于它的源代码时，它不够聪明，无法想到它。

您的“框架搜索路径”构建设置是否包含框架的路径？
