iOS Framework:找不到图片 [英] iOS Framework: image not found

问题描述

当尝试嵌入共享框架时从CMake生成进入Xcode iOS应用程序，我遇到以下问题:

When trying to embed a shared Framework generated from CMake into an Xcode iOS app, I encounter the following issue:

模型:未加载库:/Users/jones/Documents/project/build/ios/foo.framework/foo

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

引用自:/var/Containers/Bundle/Application//myapp.app/myapp

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

原因:找不到图片

似乎它具有不正确的"dylib id"，但是我不确定这到底意味着什么.注意，我的框架出现在框架"中.应用程序的文件夹(安装在手机上的内置产品").

It seems like it has an incorrect "dylib id", but I am not sure what that means exactly. Note that my framework appears in the "Frameworks" folder of the app (the built "Product" that is installed on the phone).

使用 otool -L 检查我的应用程序，我看到:

Checking my app with otool -L, I see:

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的路径在应用程序中是错误的.但是我似乎无法从Xcode更改它.

Which seems to show that the path to my framework is wrong in the app. But I can't seem to change it from Xcode.

在 Apple开发者论坛上，有人提到将DYLIB_INSTALL_NAME_BASE更改为 @来自 Build Settings->的rpath 动态库安装名称库，但不能解决我的问题.

On the Apple dev forum, somebody mentions changing DYLIB_INSTALL_NAME_BASE to @rpath from Build Settings -> Dynamic Library Install Name Base, but it doesn't solve my problem.

来自Xcode的链接器日志如下所示(可能更容易阅读此处:

The linker log coming from Xcode looks like so (maybe easier to read here:

我该如何解决?

推荐答案

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

There is actually a way to set the "install_name_dir" in CMake:

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