我如何修复我的flutter ios应用程序没有显示权限对话框我目前使用permission_handler 10.0.0软件包，该软件包在android上运行良好，但在ios上，授予或拒绝权限的对话框根本不会弹出。

chkPermissionLoc(ctx) async {
var perLocation = await Permission.location.status;
    if (perLocation.isDenied) {
        await [Permission.location].request();//This isn't running
        print('Permission is Denied');
    } else if (perLocation.isGranted) {
      print('Permission is Granted');
    } else if (perLocation.isPermanentlyDenied) {
      print('Permission is permanently denied');
    } else if (perLocation.isRestricted) {
      print('Permission is OS restricted');
    } else if (perLocation.isLimited) {
      print('Permission is Limited');
    }
}

应用程序只是打印了Permission is Denied，但是它之前的函数根本没有被调用，该函数应该显示对话框。我已经按照软件包中的文档在info.plist文件中添加了字符串值，但仍然是同一个问题。

<key>NSLocationWhenInUseUsageDescription</key>
    <string>Permission is Needed</string>
    <key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
    <string>Permission is Needed 2</string>
    <key>NSLocationUsageDescription</key>
    <string>Permission is Needed 3</string>
    <key>NSLocationAlwaysUsageDescription</key>
    <string>Permission is Needed 4</string>

任何帮助都将不胜感激

你需要添加一些代码到你的播客文件中，你可以参考flutter_permission handler in iOS。只是简单地从官方文档中复制代码，无论你需要什么权限，只要取消注解即可。

# Start of the permission_handler configuration

  # You can enable the permissions needed here. For example to enable camera
  # permission, just remove the `#` character in front so it looks like this:

  # ## dart: PermissionGroup.camera
  # 'PERMISSION_CAMERA=1'

  #  Preprocessor definitions can be found in: https://github.com/Baseflow/flutter-permission-handler/blob/master/permission_handler_apple/ios/Classes/PermissionHandlerEnums.h
  config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
    '$(inherited)',

    ## dart: PermissionGroup.calendar

    ## dart: PermissionGroup.reminders
    # 'PERMISSION_REMINDERS=1',

    ## dart: PermissionGroup.criticalAlerts
    # 'PERMISSION_CRITICAL_ALERTS=1'
  ]

end 
# End of the permission_handler configuration
