c++ - iOS 框架 : image not found

Question

尝试嵌入共享框架时 generated from CMake进入 Xcode iOS 应用程序时，我遇到了以下问题:

dyld: Library not loaded: /Users/jones/Documents/project/build/ios/foo.framework/foo

Referenced from: /var/Containers/Bundle/Application//myapp.app/myapp

Reason: image not found

它似乎有一个不正确的“dylib id”，但我不确定这到底是什么意思。请注意，我的框架出现在应用程序的“框架”文件夹中(手机上安装的内置“产品”)。

使用 otool -L 检查我的应用程序，我看到:

myapp:
    /Users/name/Documents/project/build/ios/foo.framework/foo
    /System/Library/Frameworks/Foundation.framework/Foundation
    /usr/lib/libobjc.A.dylib
    ...

这似乎表明我的框架路径在应用程序中是错误的。但我似乎无法从 Xcode 更改它。

关于 Apple dev forum ，有人提到从 Build Settings -> Dynamic Library Install Name Base 将 DYLIB_INSTALL_NAME_BASE 更改为 @rpath，但这并没有解决我的问题。

来自 Xcode 的链接器日志看起来像这样(可能更容易阅读 here :

我该如何解决这个问题？

实际上有一种方法可以在 CMake 中设置“install_name_dir”:

set_target_properties(dynamicFramework PROPERTIES
    ...
    BUILD_WITH_INSTALL_RPATH TRUE
    INSTALL_NAME_DIR @rpath
)
