【问题描述】：

我想问一下，当我已经在配置 xml 中设置了 NSCameraUsageDescription 时，为什么我仍然没有 ios 设备的摄像头权限。下面的附件照片是我运行相机功能时遇到的错误。在此之前，config.xml 对我来说是隐藏的，我使用 ionic integrations enable cordova --add 来启用和配置它。

   <platform name="ios">

       <allow-intent href="itms-apps:*" />
       <config-file parent="NSCameraUsageDescription" platform="ios" target="*-Info.plist">
           <string>You can take photos</string>
       </config-file>

Config xml

【问题讨论】：

在xcode的info.plist文件中添加摄像头权限。

【参考方案1】：

从 Cordova CLI 6.5.0 开始，您可以使用 config.xml 中的 edit-config 标记直接在 info.plist 中写入，如下所示：

<platform name="ios">

 <edit-config target="NSLocationWhenInUseUsageDescription" file="*-Info.plist" mode="merge" overwrite="true">
      <string>YOUR-PERMISSION-REQUEST</string>
 </edit-config>
 <edit-config target="NSPhotoLibraryUsageDescription" file="*-Info.plist" mode="merge" overwrite="true" >
      <string>YOUR-PERMISSION-REQUEST</string>
 </edit-config>
 <edit-config target="NSCameraUsageDescription" file="*-Info.plist" mode="merge" overwrite="true">
      <string>YOUR-PERMISSION-REQUEST</string>
 </edit-config>
</platform>

并确保您使用的是最新版本的插件，否则值可能会被插件变量覆盖。
