ios - React Native iOS 独立版在 react.ShadowQueue 上崩溃

Question

开发规范:

• Expo SDK 版本:3.0.10
• 工作流程:ExpoKit
• React Native:0.59.8
• 平台:iOS/Android

嗨!我为 iOS 和 Android 创建了一个应用程序。 Android 版本很好用，iOS 就不行了。 iOS 在启动后立即崩溃。下面是崩溃日志，我不知道如何调试它:frowning:.

它在模拟器和物理设备中崩溃。我以为可能是 Push Notification，因为它在模拟器上不起作用，我把它注释掉了，仍然老是崩溃。我猜它可能是访问设备存储。该应用程序在初始屏幕之后立即显示 ActivityIndi​​cator，同时查看设备存储以查找已保存的用户 token ，并在 ActivityIndi​​cator 显示几秒钟后崩溃。我知道它不会找到用户 token ，所以如果应该显示登录屏幕，但应用程序在此之前崩溃。我正在使用 expo-secure-store 进行本地存储。

我在 Google Drive 上有两个完整的日志:

Error-log-1.txt

Error-log-2.txt

这是简短的版本:

非常欢迎任何建议，我不知道从这里去哪里。

谢谢。

Answer 1

您可能会利用世博会来开展项目。执行命令应该是 expo start 或 expo start -ios or -android。

并且您将运行 expo eject 以使用 React native 库。

如果你想运行 iOS 的项目，

• 确保您拥有最新的 Xcode。
• 如果您还没有，请安装 CocoaPods，这是一个原生的 iOS 的依赖项管理器。
• 从项目的 ios 目录运行 pod install。

1. 然后从项目目录运行 expo start。
2. 在 Xcode 中打开项目的 xcworkspace 文件。
3. 使用Xcode 构建、安装和运行测试项目 设备或模拟器。 (如果您单击 Xcode 中的大“播放”按钮。)
