问题描述
pubspec.yaml 中的 Flutter App 版本可以通过将条目更改为在常规的 iOS Info.plist 文件中使用
<key>CFBundleShortVersionString</key>
<string>$(FLUTTER_BUILD_NAME)</string>
<key>CFBundleVersion</key>
<string>$(FLUTTER_BUILD_NUMBER)</string>
但是,我创建了一个通知服务扩展来启用 FCM 富文本推送通知,它工作正常。但是当我将此扩展的 Info.plist 值更改为与上面相同的值时,应用程序失败并显示以下构建错误:
Unable to install /Users/pa/development/FlutterApps/myApp/build/ios/iphonesimulator/Runner.app on <ID>. This is sometimes caused by a malformed plist file:
ProcessException: Process exited abnormally:
An error was encountered processing the command (domain=IXErrorDomain,code=2):

Command: xcrun simctl install <ID> /Users/pa/development/FlutterApps/myApp/build/ios/iphonesimulator/Runner.app
Error launching application on iPhone 11 Pro.
如何在 Extensions Info.plist 文件中也使用相同的变量?我认为这只是一些配置,但我无法弄清楚。
谢谢!!
解决方法
Flutter 生成一个 xcconfig
文件,其中包含 FLUTTER_BUILD_NAME
和 FLUTTER_BUILD_NUMBER
等变量
要在扩展中使用这些变量,我们需要执行以下操作:
- 转到您的扩展程序
Info.plist
并添加这些变量。
捆绑版本字符串 -- $(FLUTTER_BUILD_NAME)
捆绑版本 -- $(FLUTTER_BUILD_NUMBER)
- 转到您的项目设置并为每个配置的扩展程序选择一个

配置文件。
