Flutter iOS构建疑问：Podfile Target定义与模块配置

初始问题 #

• 构建Flutter iOS应用时失败，提示所有包需下载，不清楚Podfile中的"MyApp"应填写目录名还是应用名
• Android版本运行正常，想了解iOS构建与Android的差异，寻求包导入相关帮助

编辑1：Podfile路径错误问题 #

排查发现iOS目录下的pod install负责依赖安装，但执行时提示缺少podhelper.rb文件。从模板复制修改该文件后运行命令，出现路径错误：

/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/universal-darwin19/rbconfig.rb:229: warning: Insecure world writable dir /Users/brandonpetroski/Desktop/ticket_board-master/ticket_board-master/ios in PATH, mode 040777

[!] Invalid `Podfile` file: cannot load such file -- ../ticket_board-master/ios/Flutter/podhelper.rb.

 #  from /Users/prime/Desktop/ticket_board-master/ticket_board-master/ios/Podfile:14
 #  -------------------------------------------
 #  flutter_application_path = '../ticket_board-master'
 >  load File.join(flutter_application_path, 'ios', 'Flutter', 'podhelper.rb')
 #  
 #  -------------------------------------------

编辑2：自动生成所需文件 #

删除Android版本中隐藏的flutter-plugins-dependencies等所有生成文件，重新打开项目后，VS Code自动生成了所需的文件，准备再次构建。

编辑3：cloud_firestore模块未找到错误 #

构建取得进展，但出现Module 'cloud_firestore' not found错误。

编辑4：CocoaPods配置警告 #

参考社区内容解决模块未找到问题：统一iOS版本为11.0并运行pod install获取所需依赖包，但出现CocoaPods配置警告：

[!] CocoaPods did not set the base configuration of your project because your project already has a custom config set. In order for CocoaPods integration to work at all, please either set the base configurations of the target `Runner` to `Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig` or include the `Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig` in your build configuration (`Flutter/Release.xcconfig`).

编辑5：新的ARC语义错误 #

解决配置警告后，遇到新错误：

ARC Semantic Issue: no visible @interface for 'UIImage' declares the selector 'imageByPreparingForDisplay' 

将针对此新错误单独提问，原问题已解决，希望本记录能帮助其他从Android转Flutter iOS构建的开发者。
