添加react-native-google-mobile-ads后Expo iOS构建失败，Android正常

问题详情 #

Expo项目添加react-native-google-mobile-ads依赖后，Android端可正常构建，但iOS端构建失败。核心报错是RNGoogleMobileAdsModule.mm文件中存在BOOL到NSNumber*的类型转换不兼容问题，同时伴随多个脚本构建阶段警告，已按官方文档配置但无效。

核心构建错误 #

类型转换编译错误 #

// 错误1：第120行
GADMobileAds.sharedInstance.requestConfiguration.tagForChildDirectedTreatment = tag;
// 提示：incompatible integer to pointer conversion assigning to 'NSNumber * _Nullable' from 'BOOL'

// 错误2：第125行
GADMobileAds.sharedInstance.requestConfiguration.tagForUnderAgeOfConsent = tag;
// 提示：incompatible integer to pointer conversion assigning to 'NSNumber * _Nullable' from 'BOOL'

脚本构建警告（非致命，可暂时忽略） #

• [CP-User] Generate app.config for prebuilt Constants.manifest 脚本将在每次构建时运行
• Start Packager 脚本将在每次构建时运行
• Bundle React Native code and images 脚本将在每次构建时运行
• [CP-User] [RNGoogleMobileAds] Configuration 脚本将在每次构建时运行

构建最终结果 #

▸ ARCHIVE FAILED
▸ 编译RNGoogleMobileAdsModule.mm失败
▸ Exit status: 65

解决方案 #

1. 修复类型转换错误（核心） #

该问题是react-native-google-mobile-ads的iOS原生代码未正确将BOOL包装为NSNumber导致的，可通过patch-package打补丁解决：

• 打开node_modules/react-native-google-mobile-ads/ios/RNGoogleMobileAds/RNGoogleMobileAdsModule.mm
• 修改第120行和第125行代码：

  // 第120行修改为
  GADMobileAds.sharedInstance.requestConfiguration.tagForChildDirectedTreatment = @(tag);
  // 第125行修改为
  GADMobileAds.sharedInstance.requestConfiguration.tagForUnderAgeOfConsent = @(tag);
  

• 执行命令生成补丁：npx patch-package react-native-google-mobile-ads
• 将生成的patches/react-native-google-mobile-ads+[版本号].patch文件提交到版本控制，确保CI构建时自动应用补丁

2. 清理构建缓存 #

删除以下文件/文件夹后重新构建：

• node_modules
• ios/Podfile.lock
• ios/Pods
• 执行eas build --clean（使用EAS构建时）或npx expo prebuild --clean（裸工作流）

3. 版本兼容性检查 #

确认react-native-google-mobile-ads版本与当前Expo/React Native版本兼容，若补丁无效，尝试降级/升级到稳定兼容版本（查看库的GitHub Releases说明）

4. 脚本警告处理（可选） #

若需要消除警告，可在Xcode中打开项目，找到对应脚本构建阶段，取消勾选Based on dependency analysis，或添加输出依赖项，但此步骤不影响构建成功，可延后处理
