尝试使用 Xcode 存档 iOS 应用程序时出现“Flutter/Flutter.h 文件未找到”

Question

当我尝试存档 iOS 应用程序以上传到 AppStore 连接时，遇到一些错误。我从 Xcode 的“产品”选项卡中选择了“存档”选项。 Pod 安装完成，没有任何错误，但构建失败。确切的错误如下图所示。

我还尝试了来自终端的

flutter build ios --release

命令。但这也以错误结束。错误很长。但从如下图所示的行开始。

我尝试了多种方法，如

flutter clean

、

pod disintegrate

和

pod install

，但没有任何效果。

为了更好地理解，我在此处附加了 podfile：

# Uncomment this line to define a global platform for your project
# platform :ios, '12.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'

project 'Runner', {
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,
}

def flutter_root
  generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
  unless File.exist?(generated_xcode_build_settings_path)
    raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
  end

  File.foreach(generated_xcode_build_settings_path) do |line|
    matches = line.match(/FLUTTER_ROOT\=(.*)/)
    return matches[1].strip if matches
  end
  raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end

require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)

flutter_ios_podfile_setup

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
  target 'RunnerTests' do
    inherit! :search_paths
  end
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
   target.build_configurations.each do |config|
    config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
   end
  end
 end

Answer 1

我猜你的

Podfile

缺少对

flutter_additional_ios_build_settings

的一个重要调用。您可以采取以下措施：

1. 确保

   Flutter

   本身是最新的（在撰写本文时为

   3.24.3

   ）。如果没有 – 我强烈建议更新。

2. 在您的

   Podfile

   中，将

   flutter_additional_ios_build_settings(target)

   添加到

   post_install

   块，这样它就会开始看起来像这样：

post_install do |installer|
  installer.pods_project.targets.each do |target|
    // Line below is what you should add.
    flutter_additional_ios_build_settings(target)
    // This is your content, I left it untouched, but I'm not sure
    // if it still required though.
    target.build_configurations.each do |config|
      config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
     end
  end
end

3. 清理您的项目。清洁越深越好，但就我而言，只需

   flutter clean

   就足够了。但是，也许也值得删除

   ios/Pods

   、

   ios/.symlinks

   和

   ios/Podfile.lock

   。

4. 构建！

这些步骤足以解决我的问题，希望对您有所帮助。祝你好运！
