对于Flutter使用这个

platform :ios, '10.0'

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

您所需要做的就是取消下面这一行的注释

# platform :ios, '8.0'

OR

# platform :ios, '9.0'

等等……

然后打开终端的iOS文件夹，传递这些命令:

% pod repo update
% pod install

这个方法在扑动的时候对我很有效。打开{your_project_root_folder}/ios/Podfile，用这个替换post_install块

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

在我的情况下，我不小心导入了dart.js，所以如果它刚刚在重新加载或重新启动时停止工作，请检查您的导入

为迅速

如果你在Xcode 12中使用CocoaPods，那么你可能会看到这个错误:

The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 14.

这是因为对iOS 8的支持已经放弃，但pod的最低部署目标是iOS 8。

在此问题解决之前，您可以将以下内容添加到Podfile中:

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

这将从项目中的所有pod中删除部署目标，并允许它们继承在Podfile顶部指定的项目/工作区部署目标。

对于React Native

删除。/project-root/ios/build文件夹，输入react-native run ios

为科尔多瓦

<preference name="deployment-target" value="8.0" />
