当我在应用程序中使用 Mapbox sdk 时，无法从文件中读取属性列表，Info.plist 问题

Question

我在我的一个 flutter 应用程序中遇到了问题。我正在使用 MapBox-SDK 插件，但是当我在 IOS 上测试该应用程序时，它要求我将 Mapbox-sdk 更新到某个版本（我使用 pop install 命令执行此操作）。现在，在一切之后，我在 info.plist 文件中面临新的错误。我忘记备份旧的 info.plist 文件。\n无论如何，新的 info.plist 是：

\n\n

<plist version="1.0">\n<dict>\n<string>YES</string>\n<key>io.flutter.embedded_views_preview</key>\n<true/>\n<key>MGLMapboxAccessToken</key>\n<string>Mapbox-key-not-visible</string>\n<true/>\n<key>NSLocationWhenInUseUsageDescription</key>\n<key>NSLocationAlwaysUsageDescription</key>\n<key>NSPhotoLibraryUsageDescription</key>\n<key>NSCameraUsageDescription</key>\n<key>NSMicrophoneUsageDescription</key>\n<string>This app needs access to location when open.</string>\n<key>CFBundleDevelopmentRegion</key>\n<string>$(DEVELOPMENT_LANGUAGE)</string>\n<key>CFBundleExecutable</key>\n<string>$(EXECUTABLE_NAME)</string>\n<key>CFBundleIdentifier</key>\n<string>$(PRODUCT_BUNDLE_IDENTIFIER)</string>\n<key>CFBundleInfoDictionaryVersion</key>\n<string>6.0</string>\n<key>CFBundleName</key>\n<string>project1</string>\n<key>CFBundlePackageType</key>  \n<string>APPL</string>\n<key>CFBundleShortVersionString</key>\n<string>$(FLUTTER_BUILD_NAME)</string>\n<key>CFBundleSignature</key>\n<string>????</string>\n<key>CFBundleVersion</key>\n<string>$(FLUTTER_BUILD_NUMBER)</string>\n<key>LSRequiresIPhoneOS</key>\n<true/>\n<key>UILaunchStoryboardName</key>\n<string>LaunchScreen</string>\n<key>UIMainStoryboardFile</key>\n<string>Main</string>\n<key>UISupportedInterfaceOrientations</key>\n<array>\n    <string>UIInterfaceOrientationPortrait</string>\n    <string>UIInterfaceOrientationLandscapeLeft</string>\n    <string>UIInterfaceOrientationLandscapeRight</string>\n</array>\n<key>UISupportedInterfaceOrientations~ipad</key>\n<array>\n    <string>UIInterfaceOrientationPortrait</string>\n    <string>UIInterfaceOrientationPortraitUpsideDown</string>\n    <string>UIInterfaceOrientationLandscapeLeft</string>\n    <string>UIInterfaceOrientationLandscapeRight</string>\n</array>\n<key>UIViewControllerBasedStatusBarAppearance</key>\n<false/>\n</dict>\n</plist\n

该错误error: unable to read property list from file: Info.plist通常是由于 plist 文件中缺少配置引起的。正如前面在评论中提到的，您需要在 上设置一个值NSLocationWhenInUseUsageDescription。包的文档中解释了更多详细信息。

<key>NSLocationWhenInUseUsageDescription</key>
<string>[Your explanation here]</string>
