IPHONEOS_DEPLOYMENT_TARGET 设置为 8.0 Xcode 12 (Flutter)

Question

我运行我在 Android Studio 中的 Flutter 项目，pod 安装很顺利，但是 Xcode 每次构建都在最后失败，比如首先完成整个构建的 20/30 步. 奇怪的是 Android Studio 说：

但是当我用 Xcode 打开工作区时，我看到我在 Runner 中的目标有 iOS deployment target 14.0 所以我不明白，它应该设置为 14 但实际上它是 8。 Flutter 通过 flutter run 生成 Podfile、Podfile.lock 和 Pods 我更喜欢让 Flutter 处理 Pod 的生成和安装，而不使用 pod init、pod install 或编辑Podfile.

Answer 1

您需要在ios/Flutter/AppFrameworkInfo.plist中将MinimumOSVersion设置为9.0。它看起来像这样：

  <key>MinimumOSVersion</key>
  <string>9.0</string>

Answer 2

除了 Akif 所说的之外，这里还有一个运行可能会出现此错误的原因列表：

在ios/Flutter/AppFrameworkInfo.plist

MinimumOSversion

9.0

在 Xcode 中，确保 Runner -> Project -> Runner 的 iOS 部署目标设置为 9.0
在Xcode中，确保Runner -> Targets -> Runner中的Deployment Info设置为iOS 9.0
仔细检查您的 GoogleService-Info.plist 是否存在并且是通过 Xcode 添加的（例如不是通过 Finder copy/pasted 添加到目录中）
取消注释 ios/Podfile

#platform :iOS, '9.0'

然后，运行在您的终端中以全新状态构建以下内容：

flutter clean \
        && rm ios/Podfile.lock pubspec.lock \
        && rm -rf ios/Pods ios/Runner.xcworkspace \
        && flutter build ios

Answer 3

替换pod文件的这段代码：

post_install do |installer|
 installer.pods_project.targets.each do |target|
  target.build_configurations.each do |config|
   config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
  end
 end
end

Answer 4

enter image description here

打开xcode
更改项目文件 - 项目格式 - Xcode 8.0-兼容
flutter clean，flutter pub 获得 flutter build ios

Answer 5

错误是不言自明的，即缺少应用程序的部署目标。

这将添加到 Xcode 内的两个位置，检查下面的屏幕截图，其中提到了 iOS 部署目标 。

1.亚军

2.Pod

Answer 6

如果在尝试了上述所有解决方案后，您的代码仍然无法正常工作，尤其是在 update/upgrade...

只需检查您的 dart 版本并检查空安全包...

我通过将我的代码正确迁移到 null safety，在与错误斗争了好几天后才解决了我的问题。

Answer 7

尝试运行 in android 如果它给出任何可以修复的错误。它记得我 删除我不使用的“dart.html”导入 然后这个错误也被修复了。但在我完成此页面中的每个解决方案之前，最好记住。
