问当前应用没有位置权限，是否请求权限？

EN

我在我的应用中使用了Xamarin Forms 3.3。在iOS上调试应用程序测试时。

我的日志文件总是有两行：

2019-01-13 21:19:59.575 Marine.Mobile.iOS[2751:542039] Currently does not have Location permissions, requesting permissions

2019-01-13 21:19:59.599 Marine.Mobile.iOS[2751:542039] This app has attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain both “NSLocationAlwaysAndWhenInUseUsageDescription” and “NSLocationWhenInUseUsageDescription” keys with string values explaining to the user how the app uses this data

我在文件Info.plist中设置为Location Service

<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>Marine requires GPS to track cars and job orders</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>Marine requires GPS to track cars and job orders</string>

但不能运行或调试程序。

无法显示项目Image的名称

和错误：Image Error

我只尝试在文件Info.plist中使用以下代码

<key>NSLocationWhenInUseUsageDescription</key>
<string>Marine requires GPS to track cars and job orders</string>

=>项目可以运行调试。

然后，我试着不使用NSLocationWhenInUseUsageDescription，将其替换为NSLocationWhenInUseUsageDescription，但程序无法调试。

<key>NSLocationWhenInUseUsageDescription</key> <string>Marine requires GPS to track cars and job orders</string>

=>为什么代码无法将其添加到文件Info.plist中：

请帮帮我!谢谢!
