Flutter iOS 打包等采坑ing...

flutter打包报错记录:

  • Unexpected duplicate tasks

    处理方法:
    修改项目编译,不使用New Build System,
    在File > Project/Workspace Settings中的
    Share Project/Workspace Settings 里build system 
    将New Build System(Default)切换成Legacy build system。
    
  • ERROR: Flutter archive builds must be run in Release mode.
    To correct, ensure FLUTTER_BUILD_MODE is set to release or run:

    这个错误来源于这行命令
    /bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" build,
    你可以在Xcode->Build Phases-> Run Script中看到这行代码。
    如果打包时没有指定mode就会报错,
    需要在Build Settings中加入FLUTTER_BUILD_MODE字段,
    并根据不同环境设置为debug或release,一定要对应好,
    当设置为release时是无法在模拟器上运行的,所以不要在debug环境把这个字段设为release。
    
    Bitcode设置为NO,
    
    Preprocessor Macros添加
    FLUTTER_BUILD_MODE=Debug和FLUTTER_BUILD_MODE=Release,
    如果还有其他环境需要根据情况选择Debug或Release。
    
  • "_FlutterMethodNotImplemented", referenced from:
    -[FluttertoastPlugin handleMethodCall:result:] in FluttertoastPlugin.o
    "OBJC_CLASS$_FlutterMethodChannel", referenced from:
    objc-class-ref in FluttertoastPlugin.o
    ld: symbol(s) not found for architecture i386

    苹果iOS11后不再支持32位应用,
    具体操作是在Xcode->Target->Build Setting中
    将Build Active Architecture Only设为YES,
    并将Vaild Architecture设为[arm64, arm64e]
    
  • ld: bitcode bundle could not be generated because Flutter' was built without full bitcode.
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

    这个错误pods方式还有问题:
    以pods方式集成flutter, 还是未解决。
    https://github.com/flutter/flutter/issues/48092
    
    以framework的方式集成flutter,可以打包。
    
  • IPA processing failed

iOS13苹果取消了32位系统的支持,
而SDK包含i386 x86_64的架构,
日志IDEDistribution.standard.log

处理方法:
在程序里加一个脚本,剔除禁止的架构
TARGETS->Build Phases->New Run Script Phase
脚本内容在Flutter官方issuse里面:
https://github.com/flutter/flutter/issues/42917

  • Flutterxxx.h file not found。

    处理方法:
    每次拉取flutter代码,有插件或者依赖更新,
    都需要执行:
    flutter clean
    flutter pub get
    pods install
    
  • Flutter Framework添加后无法使用的问题。

    处理方法:
    编译设置的 General > Frameworks, Libraries, and Embedded Content 下,
    然后在 Embed 下拉列表中选择 “Embed & Sign”。
    
    编译设置中的 Framework Search Paths中
    必须对应设置debug release模式Framework路径
    
  • Found an unexpected Mach-O header。

    插件会帮助你生成 静态或动态框架。
    静态框架应该直接链接而不是嵌入。
    如果你在应用中嵌入了静态框架,
    你的应用将不能发布到 App Store。
    
    编译设置的 General > Frameworks, Libraries, and Embedded Content 下,
    然后在 Embed 下拉列表中选择 “Embed & Sign”。
    
  • flutter build iOS Error :

flutter build ios --release

看到错误信息中有Signing iOS app 并不是当前发布的app账号,

  1. 删除keys中所有其他的账号证书,只保留发布账号,
  2. .ios/runner工程中使用发布账号,修改了bundle id, 但是这个好像没有什么用,重新编译flutter的时候也会改为默认。
  3. 根据issue修改
    https://github.com/flutter/flutter/issues/18305
    https://github.com/flutter/flutter/issues/24376
1.  open ios/Runner.xcodeproj
2.  I checked Runner/Pods is empty in Xcode sidebar.
3.  drop Pods/Pods.xcodeproj into Runner/Pods.
4.  "Valid architectures" to only "arm64" (I removed armv7 armv7s) 
[13364](https://github.com/flutter/flutter/issues/13364)
5. 只支持iOS平台,并设置只支持64位,Build Settings - Architectures - Supported Platforms = ios Valid Acrchitectures = arm64
6. 将New Build System(Default)切换成Legacy build system。第一个错误设置有详细操作

错误信息:

Encountered error while building for device.

或者

error: Building for iOS, but the embedded framework 'App.framework' was built for macOS. (in target 'Runner' from project 'Runner')
Encountered error while building for device.
  • NoMethodError - undefined method `size' for nil:NilClass
  • Error running pod install
    issues处理方法
    https://github.com/CocoaPods/CocoaPods/issues/8377
// 清理的时候,如果是插件工程,一定要cd到主flutter工程和example工程 一起clean
flutter clean
rm -Rf ios/Pods
rm -Rf ios/.symlinks
rm -Rf ios/Flutter/Flutter.framework
rm -Rf ios/Flutter/Flutter.podspec

  • Failed to find assets path for "Frameworks/App.framework/flutter_assets"
    https://github.com/flutter/flutter/issues/29974
1- rm -rf ios/Flutter/App.framework

2- Change the Runner target build settings Build Phases > Thin Binary script as follows:

/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" embed
/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" thin
  • iOS 热重置连不上问题
  • iOS mDNS meta issue
  • flutter installing and launching iOS
    解决办法https://github.com/flutter/flutter/issues/46705
系统偏好设置>网络> iPhone USB>取消选中“除非需要,否则禁用”>应用。

如果没有iPhone USB,则可能需要打开热点才能使其显示,以便取消选中该设置。
该设置在启用或不启用热点的情况下都适用,启用时将导致mDNS查找失败。
  • flutter iOS 打包runner工程 ,修改DisplayName
    info.plist里面添加CFBundleDisplayName 不是直接修改CFBundleName
CFBundleDisplayName
显示的app名字

CFBundleName
