iOS端App崩溃求助：UIView未识别bridge方法（Android正常）

App在iOS平台启动后持续崩溃，但Android端运行流畅。已尝试以下操作但问题未解决：

• 删除Derived Data
• 执行pod update、pod install
• 清理Xcode构建文件夹

排查解决方案 #

• 版本兼容性检查：确认react-native-blob-util版本与当前React Native版本匹配，RN 0.60+版本需使用适配自动链接的库版本，尝试升级或降级该库至官方推荐的兼容版本。
• 重置Pod依赖：执行pod deintegrate彻底移除现有Pod配置，再执行pod install重新安装依赖，避免重复链接或配置冲突。
• 检查原生代码逻辑：查看ReactNativeBlobUtil.m中的getRCTEventDispatcher方法，确认获取RCTBridge的方式是否正确，应使用[RCTBridge currentBridge]而非错误的UIView实例。
• 清理RN缓存：执行npm start -- --reset-cache清除React Native缓存，重启Metro后重新构建iOS项目。
• 排查库冲突：临时移除近期新增的第三方原生库，逐一排查是否与react-native-blob-util存在冲突。
