Question

得益于 Catalyst ，终于可以将应用程序移植到Mac上了，问题是，许多Pod不支持AppKit。最常见的一种是Crashlytics / Firebase。

In [...]/Pods/Crashlytics/iOS/Crashlytics.framework/Crashlytics(CLSInternalReport.o), building for Mac Catalyst, but linking in object file built for iOS Simulator, file '[...]/Pods/Crashlytics/iOS/Crashlytics.framework/Crashlytics' for architecture x86_64

由于这是最近的话题，所以我无法找到有关如何从macOS的构建版本中删除pod的文档，而无法在iOS和iPadO上保留它的文档。

可以在代码中使用

#if !targetEnvironment(macCatalyst) 
// Code to exclude for your macOS app
#endif

但这是问题的一部分，另一部分是仅针对iOS链接广告连播...

如果库对于macOS而言并不重要，但在iOS上仍然需要，那么最简单/最佳的做法是什么？

Answer 1

对于处理Catalyst不受支持的framweorks的最佳方法，你们应该阅读Fernando Moya de Rivas的解决方案。

他基本上说，您只需要定义一个不想在Mac OS X上安装的所有库的数组，就像这样：['Fabric', 'Crashlytics', 'Firebase/Core', ...]。

然后，您的pod文件可以看起来像这样简单：

# Podfile
load 'remove_unsupported_libraries.rb'
target 'My target' do
   use_frameworks!
   # Install your pods
   pod ...
end

# define unsupported pods
def unsupported_pods
   ['Fabric', 'Crashlytics', 'Firebase/Core', ...]
end

# install all pods except unsupported ones
post_install do |installer|
   configure_support_catalyst installer, unsupported_pods
end

Answer 2

我有一个更新的解决方案，适用于以下Google播客：

  pod 'FirebaseUI/Auth'
  pod 'FirebaseUI/Phone'
  pod 'FirebaseUI/Email'
  pod 'Firebase/Auth'
  pod 'Firebase/Analytics'
  pod 'Fabric', '~> 1.10.2'
  pod 'Firebase/Crashlytics'
  pod 'Firebase/AdMob'

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name.start_with?("Pods")
        puts "Updating #{target.name} to exclude Crashlytics/Fabric"
      target.build_configurations.each do |config|
        xcconfig_path = config.base_configuration_reference.real_path
        xcconfig = File.read(xcconfig_path)
        xcconfig.sub!('-framework "FirebaseAnalytics"', '')
        xcconfig.sub!('-framework "FIRAnalyticsConnector"', '')
        xcconfig.sub!('-framework "GoogleMobileAds"', '')
        xcconfig.sub!('-framework "Google-Mobile-Ads-SDK"', '')
        xcconfig.sub!('-framework "GoogleAppMeasurement"', '')
        xcconfig.sub!('-framework "Fabric"', '')
        new_xcconfig = xcconfig + 'OTHER_LDFLAGS[sdk=iphone*] = $(inherited) -framework "FirebaseAnalytics"  -framework "FIRAnalyticsConnector"  -framework "GoogleMobileAds" -framework "GoogleAppMeasurement" -framework "GoogleUtilities" "-AppMeasurement" -framework "Fabric"'
        File.open(xcconfig_path, "w") { |file| file << new_xcconfig }
      end
    end
  end
end

Answer 3

在项目的Pods目录中打开Pods- $ projectname.release.xcconfig文件，然后找到OTHER_LDFLAGS行。在变量名后立即添加[sdk=iphone*]（例如，我的现在看起来像这样）：

OTHER_LDFLAGS[sdk=iphone*] = $(inherited) -ObjC -l"MailCore-ios" -l"c++" -l"iconv" -l"resolv" -l"xml2" -l"z"

这仅在构建iphone变体时有条件地设置链接选项，从而阻止Pod在OSX上链接。当然，正如您提到的那样，这需要与调用pod的代码中的#if !targetEnvironment(macCatalyst)和#endif结合使用，否则会出现链接器错误。

这使我能够克服同样的问题。（如果您想知道除条件变量之外还可以添加到.xcconfig文件中的其他有趣内容，以下是我发现的参考：https://pewpewthespells.com/blog/xcconfig_guide.html）

在@ajgryc回答之后，我提出了一个流畅的解决方案：

在您的Podfile中添加

post_install do |installer|
    installer.pods_project.targets.each do |target|
        if target.name == "Pods-[Name of Project]"
            puts "Updating #{target.name} OTHER_LDFLAGS to OTHER_LDFLAGS[sdk=iphone*]"
            target.build_configurations.each do |config|
                xcconfig_path = config.base_configuration_reference.real_path
                xcconfig = File.read(xcconfig_path)
                new_xcconfig = xcconfig.sub('OTHER_LDFLAGS =', 'OTHER_LDFLAGS[sdk=iphone*] =')
                File.open(xcconfig_path, "w") { |file| file << new_xcconfig }
            end
        end
    end
end

自Cocoapods 1.8.4

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == "Pods-[Name of Project]"
      puts "Updating #{target.name} to exclude Crashlytics/Fabric"
      target.build_configurations.each do |config|
        xcconfig_path = config.base_configuration_reference.real_path
        xcconfig = File.read(xcconfig_path)
        xcconfig.sub!('-framework "Crashlytics"', '')
        xcconfig.sub!('-framework "Fabric"', '')
        new_xcconfig = xcconfig + 'OTHER_LDFLAGS[sdk=iphone*] = -framework "Crashlytics" -framework "Fabric"'
        File.open(xcconfig_path, "w") { |file| file << new_xcconfig }
      end
    end
  end
end

然后在Fabric的运行脚本构建阶段：

if [[$ARCHS != "x86_64"]]; then
  "${PODS_ROOT}/Fabric/run" [your usual key]
fi

Answer 5

对于cocoapods 1.8.4，我不得不按如下方式修改@AncAinu的出色答案：

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == "Pods-[Name of Project]"
      puts "Updating #{target.name} to exclude Crashlytics/Fabric"
      target.build_configurations.each do |config|
        xcconfig_path = config.base_configuration_reference.real_path
        xcconfig = File.read(xcconfig_path)
        xcconfig.sub!('-framework "Crashlytics"', '')
        xcconfig.sub!('-framework "Fabric"', '')
        new_xcconfig = xcconfig + 'OTHER_LDFLAGS[sdk=iphone*] = -framework "Crashlytics" -framework "Fabric"'
        File.open(xcconfig_path, "w") { |file| file << new_xcconfig }
      end
    end
  end
end

Answer 6

基于此处已讨论的内容...这是我针对具有多个目标的项目的解决方案。基本上是在验证每个目标上的库的用法，而不是遵循目标名称。

post_install do |installer|
    
    installer.pods_project.targets.each do |target|
        
        # handle non catalyst libs
        libs = ["FirebaseAnalytics", "Google-Mobile-Ads-SDK"]
        
        target.build_configurations.each do |config|
            xcconfig_path = config.base_configuration_reference.real_path
            xcconfig = File.read(xcconfig_path)
            values = ""
            
            libs.each { |lib|
                if xcconfig["-framework \"#{lib}\""]
                    puts "Found '#{lib}' on target '#{target.name}'"
                    xcconfig.sub!(" -framework \"#{lib}\"", '')
                    values += " -framework \"#{lib}\""
                end
            }
            
            if values.length > 0
                puts "Preparing '#{target.name}' for Catalyst\n\n"
                new_xcconfig = xcconfig + 'OTHER_LDFLAGS[sdk=iphone*] = $(inherited)' + values
                File.open(xcconfig_path, "w") { |file| file << new_xcconfig }
            end
        end
    end
end
