Klasse ist in beiden implementiert, einer der beiden wird verwendet. Welches ist undefiniert

Ich habe auch ein anderes Skript gefunden, das jemand geschrieben hat und das den Fehler automatisch behebt. Es ist einfach das Gleiche zu machen, was ich oben beantwortet habe. Fügen Sie es Ihrem Podfile hinzu:

post_install do |installer|
    sharedLibrary = installer.aggregate_targets.find { |aggregate_target| aggregate_target.name == 'Pods-[MY_FRAMEWORK_TARGET]' }
    installer.aggregate_targets.each do |aggregate_target|
        if aggregate_target.name == 'Pods-[MY_APP_TARGET]'
            aggregate_target.xcconfigs.each do |config_name, config_file|
                sharedLibraryPodTargets = sharedLibrary.pod_targets
                aggregate_target.pod_targets.select { |pod_target| sharedLibraryPodTargets.include?(pod_target) }.each do |pod_target|
                    pod_target.specs.each do |spec|
                        frameworkPaths = unless spec.attributes_hash['ios'].nil? then spec.attributes_hash['ios']['vendored_frameworks'] else spec.attributes_hash['vendored_frameworks'] end || Set.new
                        frameworkNames = Array(frameworkPaths).map(&:to_s).map do |filename|
                            extension = File.extname filename
                            File.basename filename, extension
                        end
                    end
                    frameworkNames.each do |name|
                        if name != '[DUPLICATED_FRAMEWORK_1]' && name != '[DUPLICATED_FRAMEWORK_2]'
                            raise("Script is trying to remove unwanted flags: #{name}. Check it out!")
                        end
                        puts "Removing #{name} from OTHER_LDFLAGS"
                        config_file.frameworks.delete(name)
                    end
                end
            end
            xcconfig_path = aggregate_target.xcconfig_path(config_name)
            config_file.save_as(xcconfig_path)
        end
    end
end

Aktualisiert: Ich schreibe einen Blog-Artikel für meine Lösung: https://medium.com/@GalvinLi/tinysolution-fix-cocoapods-duplicate-implement-warning-5a2e1a505ea8

Und ein Demo-Projekt: https://github.com/bestwnh/TinySolution

Ich habe die Lösungsidee aus dem Internet erhalten, kann aber keine Lösung finden, daher kann ich sie selbst umgehen. Vielleicht ist der Code ein bisschen lang, aber es funktioniert. Hoffe es kann jemandem helfen.

Die auto_process_target(,,) ist die Schlüsselfunktion, passen Sie sie einfach an Ihr Projekt an und alles sollte gut funktionieren. (Da ich ein Framework für mehrere App-Ziele verwende, muss der Parameter für das App-Ziel ein Array sein.)

post_install do |installer|

  # you should change the sample auto_process_target method call to fit your project

  # sample for the question
  auto_process_target(['MyFrameworkExampleApp'], 'MyFramework', installer)
  # sample for the multi app use on same framework
  auto_process_target(['exampleiOSApp', 'exampleMacApp'], 'exampleFramework', installer)

end

# the below code no need to modify

def auto_process_target(app_target_names, embedded_target_name, installer)
  words = find_words_at_embedded_target('Pods-' + embedded_target_name,
                                        installer)
  handle_app_targets(app_target_names.map{ |str| 'Pods-' + str },
                     words,
                     installer)
end

def find_line_with_start(str, start)
  str.each_line do |line|
      if line.start_with?(start)
        return line
      end
  end
  return nil
end

def remove_words(str, words)
  new_str = str
  words.each do |Word| 
    new_str = new_str.sub(Word, '')
  end
  return new_str
end

def find_words_at_embedded_target(target_name, installer)
  target = installer.pods_project.targets.find { |target| target.name == target_name }
  target.build_configurations.each do |config|
    xcconfig_path = config.base_configuration_reference.real_path
    xcconfig = File.read(xcconfig_path)
    old_line = find_line_with_start(xcconfig, "OTHER_LDFLAGS")

    if old_line == nil 
      next
    end
    words = old_line.split(' ').select{ |str| str.start_with?("-l") }.map{ |str| ' ' + str }
    return words
  end
end

def handle_app_targets(names, words, installer)
  installer.pods_project.targets.each do |target|
    if names.index(target.name) == nil
      next
    end
    puts "Updating #{target.name} OTHER_LDFLAGS"
    target.build_configurations.each do |config|
      xcconfig_path = config.base_configuration_reference.real_path
      xcconfig = File.read(xcconfig_path)
      old_line = find_line_with_start(xcconfig, "OTHER_LDFLAGS")

      if old_line == nil 
        next
      end
      new_line = remove_words(old_line, words)

      new_xcconfig = xcconfig.sub(old_line, new_line)
      File.open(xcconfig_path, "w") { |file| file << new_xcconfig }
    end
  end
end

Wenn alle funktionieren. Du wirst sehen Update xxxx OTHER_LDFLAGS wenn du pod install oder pod update. Dann war die Warnung weg.
