我升级到 expo 34.0.3 和相关的依赖项如下

"dependencies": {
    "@expo/samples": "3.0.3",
    "@expo/vector-icons": "^10.0.3",
    "add": "^2.0.6",
    "expo": "^34.0.3",
    "expo-asset": "^5.0.1",
    "expo-font": "~6.0.1",
    "moment": "^2.24.0",
    "react": "16.8.3",
    "react-native": "https://github.com/expo/react-native/archive/sdk-34.0.0.tar.gz",
    "react-native-gesture-handler": "^1.3.0",
    "react-native-modal": "^11.3.1",
    "react-native-modal-datetime-picker": "^7.5.0",
    "react-native-snackbar-component": "^1.1.0",
    "react-navigation": "^3.11.1",
    "react-redux": "^7.1.0",
    "redux": "^4.0.4",
    "redux-persist": "^5.10.0"
  },

我的 App.js 大概像这样正确地预加载了字体

  import * as Font from 'expo-font';
  import * as Icon from '@expo/vector-icons';

   .........


  _loadResourcesAsync = async () => {
    return Promise.all([
      Font.loadAsync({
        ...Icon.Ionicons.font,
        ...Icon.MaterialCommunityIcons.font,
      }),
    ]);
  };

现在要明确一点，这段代码在世博升级之前工作得很好。此问题在 Android 和 iOS 设备上都存在。
