Console.error: 未检测到权限处理程序。(React Native)

Question

我正在编写一个简单的 React Native 应用程序，并且在运行该应用程序时出现控制台错误。它说没有检测到权限处理程序并告诉我执行一些步骤。但是我不知道如何执行这些步骤，如果它们不起作用，我不知道如何解决问题。

这是错误：

这是 podfile：

platform :ios, '9.0'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

请帮忙。谢谢。

Answer 1

在 podFile 中添加了这些

  permissions_path = '../node_modules/react-native-permissions/ios'
  pod 'Permission-LocationAlways', :path => "#{permissions_path}/LocationAlways/Permission-LocationAlways.podspec"
  pod 'Permission-LocationWhenInUse', :path => "#{permissions_path}/LocationWhenInUse/Permission-LocationWhenInUse.podspec"

然后运行pod install 对我来说这有效。

Answer 2

如果您正在使用use_frameworks!（例如对于 firebase 应用程序）

根据文档，添加以下内容以将所有权限 Pod 转换为静态库。

pre_install do |installer|
  Pod::Installer::Xcode::TargetValidator.send(:define_method, :verify_no_static_framework_transitive_dependencies) {}

  installer.pod_targets.each do |pod|
    if pod.name.eql?('RNPermissions') || pod.name.start_with?('Permission-')
      def pod.build_type;
        Pod::BuildType.static_library
      end
    end
  end
end

之后为您的应用程序添加必要的权限use_react_native!(...)：

use_react_native!(
    :path => config[:reactNativePath],
    :hermes_enabled => false,
    :fabric_enabled => flags[:fabric_enabled],
  )

  permissions_path = '../node_modules/react-native-permissions/ios'
  pod 'Permission-LocationAccuracy', :path => "#{permissions_path}/LocationAccuracy"
  pod 'Permission-LocationWhenInUse', :path => "#{permissions_path}/LocationWhenInUse"

在XCode => Product => Clean Project Clean Derived 数据中清理您的项目 ：

rm -rf ~/Library/Developer/Xcode/DerivedData

注意：关闭IOS模拟器

您也可以转到 ios 文件夹并删除Podfile.lock和Pods文件夹。

安装 Pod： npx pod-install或cd ios && pod install

尝试运行您的应用程序。

yarn ios 或者 npm run ios

Answer 3

您只需要安装 RN Permissions 并对 podfile 和 info.plist 进行更改。根据您需要的权限，您可以获得 pod。如果您不确定，请全部执行。您可以在https://www.npmjs.com/package/react-native-permissions找到代码。还有一些其他的事情你可能需要做——那些我没有提到但在链接的 npm 文档中。

Answer 4

他们在文档中提到了这个问题，并建议修复该问题并且它有效。清除 Xcode 缓存对我有用:)

解决方案：

如果您看到“未检测到权限处理程序”错误：请确保您至少设置了一个权限处理程序。在某些情况下，需要清除 Xcode 缓存（Xcode -> 产品 -> 清理构建文件夹）
