如何在iOS APP中手动包含动态库 [英] How to manually include a dynamic library in an iOS APP

问题描述

我有一个iOS应用程序(不是用xcode制作的)，我需要在其中包含一个动态库.我的计算机上有这个库:

I have an iOS app (not made with xcode) and I need to include in it a dynamic library. I have this library on my computer:

\webrtc
    \WebRTC.framework
        \Headers
            \*.h
        \Modules
            \module.modulemap
        \WebRTC
        \Info.plist

然后像这样将这些文件部署到我的应用程序中:

and I deploy those files inside my app like this :

ALLiveVideoChatClient.app
    \Frameworks
        \WebRTC.framework
            \Headers
                \*.h
            \Modules
                \module.modulemap
            \WebRTC
            \Info.plist

当我这样做

otool -L ALLiveVideoChatClient.app/ALLiveVideoChatClient

返回我:

@rpath/WebRTC.framework/WebRTC (compatibility version 0.0.0, current version 0.0.0)

，当我尝试运行我的应用程序时，收到错误消息:

and when I try to run my app I receive the error:

异常类型:EXC_CRASH(SIGABRT)异常代码: 0x0000000000000000、0x0000000000000000异常注: EXC_CORPSE_NOTIFY终止描述:DYLD，库未加载: @ rpath/WebRTC.framework/WebRTC |引用自: /var/containers/Bundle/Application/A2C3A7DA-D35E-4649-AEA0-9AB518E48971/ALLiveVideoChatClient.app/ALLiveVideoChatClient |原因:未找到图片由线程触发:0

所以我检查@rpath的值

so I check the value of @rpath doing

otool -l ALLiveVideoChatClient.app/ALLiveVideoChatClient

它返回了我

cmd LC_RPATH
cmdsize 32
path $ORIGIN (offset 12)

我不确定$ORIGIN是什么意思，但是将其指向ALLiveVideoChatClient.app，所以我将@rpath更新为指向$ORIGIN/Frameworks，将-rpath $ORIGIN/Frameworks添加到链接器中(

I m not sure what mean $ORIGIN but seam it's point to ALLiveVideoChatClient.app so i update the @rpath to point to $ORIGIN/Frameworks adding -rpath $ORIGIN/Frameworks to the linker (http://www.manpagez.com/man/1/ld/) but i still receive the error image not found

我做错了什么?将动态库手动添加(因此无需xcode)到iOS应用的步骤是什么?

What I did wrong? What are the steps to manually add (so without xcode) a dynamic library to an iOS app?

推荐答案

WebRTC.framework是一个嵌入式框架，您需要将其嵌入到您的应用程序中.如果没有，则会出现上述错误.

WebRTC.framework is an embedded framework and you need to embed it with your app. If not, you will get above mentioned error.

要嵌入，请进入构建设置.您将找到有关嵌入式框架"的部分.点击+图标.它将显示您包含在应用程序中的框架的列表，然后选择WebRTC框架.此处的更多详细信息 Apple TechNote-在应用程序中嵌入框架

To embed, go to build settings. You will find a section on "Embed Frameworks". Click on + icon. It will show you list of frameworks you have included in your app, select WebRTC framework. More details here Apple TechNote - Embedding Frameworks In An App

另一方面，我发现Google决定从WebRTC中删除静态库目标是荒唐的.我们修改了build.gn()以生成静态库并改为使用它.如果需要，我可以分享.

On a side note, I find Google decision to remove static library target from WebRTC absurd. We have modified build.gn(s) to generate static library and using it instead. If you need, I can share it.
