这是一个裸反应的原生项目。

我正在使用的代码：

import * as unimodules from 'react-native-unimodules';
// ...
    unimodules.Permissions.getAsync(unimodules.Permissions.LOCATION)
      .then(console.info)
      .catch(console.error)

; package.json 中的版本

"react-native-unimodules": "^0.7.0",

在纱线锁

expo-permissions@~8.0.0:
  version "8.0.0"
  resolved "https://registry.yarnpkg.com/expo-permissions/-/expo-permissions-8.0.0.tgz#5a45e8451dd7ff37c9e6ce5e2447818372547813"

save error about some other permission type (Permissions.NOTIFICATIONS works fine, while Permissions.CAMERA does not)

所以我开始检查代码。权限列表在这里定义

似乎错误来自这里https://github.com/expo/expo/blob/master/packages/expo-permissions/ios/EXPermissions/EXPermissions.m#L69

https://github.com/expo/expo/blob/master/packages/expo-permissions/src/Permissions.ts#L28。它是一个列表。

但是在这里https://github.com/expo/expo/blob/master/packages/expo-permissions/ios/EXPermissions/EXPermissions.m#L58我看到了

  [self registerRequesters:@[userNotificationRequester, remoteNotificationRequester]];

仅用于通知。因此，该代码意味着getAsync仅适用于Notifications. 这是真的吗？我什至不明白如何向世博团队报告这个问题。

好的。奇怪的是它没有在文档中发现。

这registerRequesters是从其他博览会模块中调用的。所以要使用location权限请求，我必须安装expo-location. 该模块在此处注册请求者：

https://github.com/expo/expo/blob/8b45846976d16b28329bd5fb067040c16db50089/packages/expo-location/ios/EXLocation/EXLocation.m#L63

如果您遇到类似问题，其他模块似乎相同
