Just go to your info.plistand add the following keys
只需转到您的info.plist并添加以下键
String that you provide to these keys will be picked appropriately by iOS to show the message of the dialog when you request for user permission to access the location.
String that you provide to these keys will be picked appropriately by iOS to show the message of the dialog when you request for user permission to access the location.
Which message will be picked will be decided dynamically based on what kind of permission you are asking for. Eg : when you ask for Location Always permission its corresponding message will be picked and vice versa when you use location when in use.
将根据您要求的权限类型动态决定选择哪条消息。例如：当您请求位置始终许可时，将选择其相应的消息，反之亦然，当您在使用时使用位置。
Hope it helps

Open your plist with source code, and add below
<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>Message for Always and when used desc</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>Message for Always used desc</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>Message for when used desc</string>

For iOS Devices you need to specifiy NSLocationAlwaysUsageDescriptionor NSLocationWhenInUseUsageDescriptiondirectly in your Info.plist file in xCode. After that iOS will automatically manage to show your specified message in an alert.
对于 iOS 设备，您需要在 xCode中的 Info.plist 文件中指定NSLocationAlwaysUsageDescription或NSLocationWhenInUseUsageDescription直接指定。之后，iOS 将自动设法在警报中显示您指定的消息。
