Expo 47升级至48后启动崩溃：-[__NSCFNumber count]未识别选择器错误

项目从Expo 47版本升级到48版本后，启动直接崩溃。几乎未修改代码，即使禁用所有JavaScript代码仅返回空视图，崩溃仍会发生。

解决方案 #

从堆栈日志可判断，崩溃由FBSDKCoreKit触发，原因是SDK尝试对NSCFNumber类型调用count方法，属于类型不匹配问题，大概率是版本兼容或配置错误导致，可按以下步骤排查：

• 升级Facebook相关依赖：确保react-native-fbsdk-next等依赖适配Expo 48（对应RN 0.71），直接更新到最新兼容版本。
• 修正配置类型：检查app.json/app.config.js中的Facebook配置，facebookAppId等字段必须是字符串类型，避免传入数字导致SDK解析错误。
• 清理构建缓存：
  1. 删除iOS目录下的Pods文件夹和Podfile.lock
  2. 执行pod install重新安装依赖
  3. 运行npx expo start --clear清除Expo缓存
• 升级CocoaPods：当前使用1.12.0，建议升级到1.13+稳定版，执行brew upgrade cocoapods
• 临时移除验证：如果暂时不需要Facebook功能，移除相关依赖和配置，确认应用是否能正常启动，锁定问题根源。
