I spent a couple of days trying to figure out the errors from building with Unity Cloud Build vs building locally. Hopefully this can help someone else!

我花了几天时间试图找出使用 Unity Cloud Build 构建与本地构建的错误。希望这可以帮助别人！

Building Locally

本地建设

This just worked as long as you have CocoaPods installed. An error will appear in the Unity console after building for iOS if CocoaPods is not installed. Other than that, the instructions provided by Firebase worked fine with Unity 5.6 and Xcode 8.3.

只要您安装了 CocoaPods，这就会起作用。如果未安装 CocoaPods，则在为 iOS 构建后，Unity 控制台中将出现错误。除此之外，Firebase 提供的说明适用于 Unity 5.6 和 Xcode 8.3。

Building with Unity Cloud Build

使用 Unity Cloud Build 构建

CocoaPods is not available on UCB but Firebase has a non-CocoaPods alternative: https://firebase.google.com/docs/ios/setup#frameworks

CocoaPods 在 UCB 上不可用，但 Firebase 有一个非 CocoaPods 替代方案：https://firebase.google.com/docs/ios/setup#frameworks

Add Frameworks Manually

手动添加框架

The instructions are assuming a native iOS build but you can simply drag the frameworks you need into Assets/Plugins/iOS/Firebase instead of into an Xcode project. Unity will add those frameworks to the Xcode project on build.

这些说明假设使用原生 iOS 构建，但您可以简单地将您需要的框架拖入 Assets/Plugins/iOS/Firebase 而不是 Xcode 项目。Unity 将在构建时将这些框架添加到 Xcode 项目中。

Add Linker Flag

添加链接器标志

You will need to manually add -ObjCinto Other Link Flags. For some reason it showed up in my local Xcode project but not when UCB made the build. Create a post process script much like maros mentioned: https://forum.unity3d.com/threads/problem-building-ios-app-with-cloud-build-using-google-analytics.390803/#post-2549911

您将需要手动添加-ObjC到其他链接标志。出于某种原因，它出现在我本地的 Xcode 项目中，但没有出现在 UCB 进行构建时。创建一个类似于 maros 提到的后期处理脚本：https://forum.unity3d.com/threads/problem-building-ios-app-with-cloud-build-using-google-analytics.390803/#post-2549911

You will need to add -ObjClike this:

您需要-ObjC像这样添加：

proj.AddBuildProperty(target, "OTHER_LDFLAGS", "-ObjC");

If you do not add this part, UCB may still create a build but the game will crash immediately after trying to create FirebaseAuth as it will reference an extension/category method that was not included due to the missing -ObjCflag.

如果您不添加此部分，UCB 可能仍会创建构建，但在尝试创建 FirebaseAuth 后游戏将立即崩溃，因为它将引用由于缺少-ObjC标志而未包含的扩展/类别方法。

Add Other Required Frameworks and Libraries

添加其他必需的框架和库

Depending on which Firebase features you are using, you may need different additional frameworks or libs. For example I had used FirebaseDatabase and while the docs did not mention this, Xcode complained about a linker error that required me to add libicucore.tbd.

根据您使用的 Firebase 功能，您可能需要不同的额外框架或库。例如，我使用过 FirebaseDatabase，虽然文档没有提到这一点，但 Xcode 抱怨链接器错误，需要我添加libicucore.tbd.

The best way I could think to solve this was uninstall CocoaPods locally and then have Unity create the Xcode project so that I could get a more accurate representation of what UCB would experience. This part may take some trial and error as well as Googling to figure out which framework or lib the linker error is referring to. Just try to build the Xcode project locally and you will get the linker errors if any.

我认为解决这个问题的最好方法是在本地卸载 CocoaPods，然后让 Unity 创建 Xcode 项目，这样我就可以获得更准确的 UCB 体验。这部分可能需要一些试验和错误以及谷歌搜索来找出链接器错误所指的框架或库。只需尝试在本地构建 Xcode 项目，您就会收到链接器错误（如果有）。

I added:

我补充说：

List<string> frameworks = new List<string>() {
    "AdSupport.framework",
    "CoreData.framework",
    "SystemConfiguration.framework",
    "libz.dylib",
    "libsqlite3.dylib",
    "libicucore.tbd"
};

Manually Move GoogleServices-Info.plist

手动移动 GoogleServices-Info.plist

Another oddity is that UCB did not move the GoogleServices-Info.plist into the Xcode project. There must be some other script that is not running on UCB that does run locally. In the post process script where you add the linker flag and frameworks, you can also move the GoogleServices-Info.plist into the Xcode project directory and then add it to the bundle.

另一个奇怪的是 UCB 没有将 GoogleServices-Info.plist 移动到 Xcode 项目中。必须有一些其他脚本不在本地运行的 UCB 上运行。在添加链接器标志和框架的后期处理脚本中，您还可以将 GoogleServices-Info.plist 移动到 Xcode 项目目录中，然后将其添加到包中。

First move the file:

首先移动文件：

if (!File.Exists(path + "/GoogleService-Info.plist"))
{
    FileUtil.CopyFileOrDirectory ("GoogleService-Info.plist", path + "/GoogleService-Info.plist");
}

Then add it to the build:

然后将其添加到构建中：

string guid = proj.AddFile("GoogleService-Info.plist", "GoogleService-Info.plist");
proj.AddFileToBuild(target, guid);

And that should be it. I will update if I run into any other issues as I add more Firebase features. Currently I am using Auth, Database, and Analytics.

应该就是这样。如果我在添加更多 Firebase 功能时遇到任何其他问题，我会更新。目前我正在使用身份验证、数据库和分析。

A lot has been said on the subject, but it took me a lotof time and a lotof trial and error to gather all the pieces on both SO & Unity forums, so I will just post the solution that I finally worked out, which finally solved all issues for me, using unity cloud build/Unity 5.6.0f3/Xcode 8.0, the project using only firebase analytics package

关于这个主题已经说了很多，但是我花了很多时间和大量的反复试验来收集 SO 和 Unity 论坛上的所有内容，所以我只会发布我最终制定的解决方案，其中最终为我解决了所有问题，使用 unity cloud build/Unity 5.6.0f3/Xcode 8.0，该项目仅使用了 firebase 分析包

completely disable cocoapods from Unity > Assets > Play Services Resolver > iOS Resolver > Settings (uncheck "Podfile Generation" and "Auto Install Cocoapod Tools in Editor", choose "None - do not integrate Cocoapods") p
put GoogleServices-Info.plist in the Unity "Assets" folder
PostBuildProcessor method:

从 Unity > Assets > Play Services Resolver > iOS Resolver > Settings 中完全禁用 cocoapods（取消选中“Podfile Generation”和“Auto Install Cocoapod Tools in Editor”，选择“None - do not integration Cocoapods”）p

    // Only perform these steps for iOS builds
    #if UNITY_IOS

    Debug.Log ("[UNITY_IOS] ProcessPostBuild - Adding Google Analytics frameworks.");

    // Go get pbxproj file
    string projPath = path + "/Unity-iPhone.xcodeproj/project.pbxproj";

    // PBXProject class represents a project build settings file,
    // here is how to read that in.
    PBXProject proj = new PBXProject ();
    proj.ReadFromFile (projPath);
    // This is the Xcode target in the generated project
    string target = proj.TargetGuidByName("Unity-iPhone");

    }
    string guid = proj.AddFile("GoogleService-Info.plist", "GoogleService-Info.plist");
    proj.AddFileToBuild(target, guid);

    // List of frameworks that will be added to project
    List<string> frameworks = new List<string>() {
        "AddressBook.framework",
        "AdSupport.framework",
        "CoreData.framework",
        "SystemConfiguration.framework",
    };

    // Add each by name
    frameworks.ForEach((framework) => {

    usrLibFrameworks.ForEach((framework) => {
        proj.AddFileToBuild(target, proj.AddFile("usr/lib/"+ framework, "Frameworks/" + framework, PBXSourceTree.Sdk));
    });


    // Write PBXProject object back to the file
    proj.WriteToFile (projPath);

    #endif
}

PS it's crazy that firebase unity sdk is requiring such hacks to work (UCB is an absolute requirement for us and I guess for most multiplatform mobile developers) and I hope all those workarounds will soon be useless, but judging that all those issues are here from the beginning of official firebase Unity support, I wouldn't count too much on it

PS，firebase unity sdk 需要这样的 hack 来工作真是太疯狂了（UCB 是我们的绝对要求，我想对于大多数多平台移动开发人员来说），我希望所有这些解决方法很快就会无用，但判断所有这些问题都来自Firebase Unity 官方支持的开始，我不会太指望它

Find the Podfile file and open it in a text editor. remove

找到 Podfile 文件并在文本编辑器中打开它。消除

, :integrate_targets => false

, :integrate_targets => 假

in the second line so it says: install! 'cocoapods'

在第二行，它说：安装！“可可豆”

Then add a new line after platform: ios...

然后在平台后添加一个新行：ios...

use_frameworks!

使用_框架！

Then open a terminal screen and go to the directory of this project. Type 'pod install' and enter. If everything goes well a workspace file is created and a message appears that you should open the workspace in Xcode in stead of the project. So close the project in xcode and open the projectname.xcworkspace file. Now Xcode will open the workspace and you will be able to run the project. You may have to adjust your Deployment Target to 8.0. Hope this works for you

然后打开一个终端屏幕并转到该项目的目录。输入“pod install”并输入。如果一切顺利，就会创建一个工作区文件，并显示一条消息，提示您应该在 Xcode 中打开工作区而不是项目。所以在xcode中关闭项目，打开projectname.xcworkspace文件。现在 Xcode 将打开工作区，您将能够运行该项目。您可能需要将部署目标调整为 8.0。希望这对你有用

I just figure it out , just use older version in your pod file created by unity to be like this

我只是想通了，只需在您的 pod 文件中使用由 unity 创建的旧版本，就像这样

target 'Unity-iPhone' do pod 'Firebase/Analytics', '3.17.0' pod 'Firebase/Auth', '3.17.0' pod 'Firebase/Core', '3.17.0' pod 'Google-Mobile-Ads-SDK', '7.13' end

目标 'Unity-iPhone' do pod 'Firebase/Analytics', '3.17.0' pod 'Firebase/Auth', '3.17.0' pod 'Firebase/Core', '3.17.0' pod 'Google-Mobile-Ads -SDK', '7.13' 结束

///note: //

Don't forgot to set the Enable Modules (c and Objective-c) to yes in building setting for (Google-Mobile-Ads-SDK)

不要忘记在（Google-Mobile-Ads-SDK）的构建设置中将启用模块（c和Objective-c）设置为yes

then open folder from terminal and run: ->pod install to update pods
