升级iOS14以后发现项目报错了，提示

for “xxxxx” requires a development team. Select a development team in the Signing & Capabilities editor.”

有的第三方需要设置签名，遇到这种情况我们有以下四种解决办法

1.自己依次找到报错的第三方，自己设置签名和配置文件。这个不推荐，每次pod以后，都需要重新设置

2.设置自定义签名（根据当前的项目签名，自动配置第三方的签名）

这个方法比较推荐

在podfile文件的末尾加上

post_install do |installer|
  # Get main project development team id
  dev_team = ""
  project = installer.aggregate_targets[0].user_project
  project.targets.each do |target|
      target.build_configurations.each do |config|
          if dev_team.empty? and !config.build_settings['DEVELOPMENT_TEAM'].nil?
              dev_team = config.build_settings['DEVELOPMENT_TEAM']
          end
      end
  end

  installer.pods_project.targets.each do |target|
    if target.respond_to?(:product_type) and target.product_type == "com.apple.product-type.bundle"
        target.build_configurations.each do |config|
            config.build_settings['DEVELOPMENT_TEAM'] = dev_team
        end
    end
  end
end

3.设置自定义签名（手动配置当前项目签名）

这个方法不灵活，不推荐，需要自己把teamId写上

在podfile文件的末尾加上

post_install do |installer|
  installer.generated_projects.each do |project|
    project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings["DEVELOPMENT_TEAM"] = " Your Team ID  "
         end
    end
  end
end

4.设置第三方不签名

这个方法从根源解决问题

在podfile文件的末尾加上

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.respond_to?(:product_type) and target.product_type == "com.apple.product-type.bundle"
      target.build_configurations.each do |config|
          config.build_settings['CODE_SIGNING_ALLOWED'] = 'NO'
      end
    end
  end
end
