什么是 React Native 权限以及如何使用它？

Question

如何使用React Native权限库？我已经开始学习它告诉我使用库的最佳实践？

Answer 1

应用权限通过保护对以下内容的访问来帮助保护用户隐私：

受限数据，例如系统状态和用户联系信息。
限制操作，例如连接到配对设备和录制音频。 react-native-permissions iOS、Android 和 Windows 上 React Native 的统一权限 API。您可以通过以下命令从终端安装它

$ npm install --save react-native-permissions

--- 或 ---

$纱加react-native-permissions

了解权限流程由于 iOS 和 Android 上的权限处理方式不同，此库提供了对两个平台行为的抽象。（在此处查看详细信息）。更新 Pod 文件以安装权限处理程序。默认情况下没有安装权限处理程序。更新您的 Podfile，方法是选择您要检查或请求的文件，然后运行pod 安装。

Example

    target 'YourAwesomeProject' do
    
      # …
    
      permissions_path = '../node_modules/react-native-permissions/ios'
    
      pod 'Permission-AppTrackingTransparency', :path => "#{permissions_path}/AppTrackingTransparency"
      pod 'Permission-BluetoothPeripheral', :path => "#{permissions_path}/BluetoothPeripheral"
      pod 'Permission-Calendars', :path => "#{permissions_path}/Calendars"
      pod 'Permission-Camera', :path => "#{permissions_path}/Camera"
      pod 'Permission-Contacts', :path => "#{permissions_path}/Contacts"
    
    end

然后用想要的权限使用说明更新您的Info.plist：

        <?xml version="1.0" encoding="UTF-8"?>
        <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" 
        "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
        <plist version="1.0">
        <dict>
        
          <!--  Keep only the permissions used in your app  -->
        
          <key>NSAppleMusicUsageDescription</key>
          <string>YOUR TEXT</string>
          <key>NSBluetoothAlwaysUsageDescription</key>
          <string>YOUR TEXT</string>
            <key>YOUR-PURPOSE-KEY</key>
           </dict>
        </dict>
        </plist>

对于Android 将所有想要的权限添加到您的应用程序 android/app/src/main/AndroidManifest.xml 文件：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.myawesomeapp">

  <!--  Keep only the permissions used in your app  -->
  <uses-permission android:name="android.permission.BLUETOOTH_ADVERTISE" 
  />
  <uses-permission android:name="android.permission.BLUETOOTH_CONNECT" 
  />
  <uses-permission android:name="android.permission.BLUETOOTH_SCAN" />

  <!-- … -->

</manifest>

然后像下面这样使用它

 import {check, PERMISSIONS, RESULTS} from 'react-native-permissions';

check(PERMISSIONS.IOS.LOCATION_ALWAYS)
  .then((result) => {
    switch (result) {
      case RESULTS.UNAVAILABLE:
        console.log('This feature is not available (on this device / in 
        this context)');
        break;
      case RESULTS.DENIED:
        console.log('The permission has not been requested / is denied 
        but requestable');
        break;
      case RESULTS.LIMITED:
        console.log('The permission is limited: some actions are 
        possible');
        break;
      case RESULTS.GRANTED:
        console.log('The permission is granted');
        break;
      case RESULTS.BLOCKED:
        console.log('The permission is denied and not requestable 
        anymore');
        break;
    }
  })
  .catch((error) => {
    // …
  });
