c# - 禁用对位置服务 API 的访问

Question

如何禁用对位置服务 API 的访问？

我确实收到了一封来自 Microsoft 开发中心的信，其中包含此提示:

Your app must provide in-app settings that allow the user to enable and disable your app's access to and use of location from the Location Service API.

任何人都可以提供有关我如何执行此操作的进一步帮助吗？

Answer 1

将此代码粘贴到 MainPage.xaml 中的 InitializeComponent(); 之后。您必须通过此行using System.IO.IsolatedStorage;添加对IsolatedStorage的引用。

if (IsolatedStorageSettings.ApplicationSettings.Contains("LocationConsent"))
{
    return;
}
else
{
    MessageBoxResult result = MessageBox.Show("Allow this app to access your location?", "Location", MessageBoxButton.OKCancel);

    if (result == MessageBoxResult.OK)
    {
       IsolatedStorageSettings.ApplicationSettings["LocationConsent"] = true;
    }
    else
    {
       IsolatedStorageSettings.ApplicationSettings["LocationConsent"] = false;
    }
    IsolatedStorageSettings.ApplicationSettings.Save();
}

还创建一个带有 ToggleSwitch 的 Settings.xaml 页面，其中包含以下代码:

if (IsolatedStorageSettings.ApplicationSettings.Contains("LocationConsent"))
{
    if ((bool)IsolatedStorageSettings.ApplicationSettings["LocationConsent"] == true)
    {
       locationSwitch.IsChecked = true;
    }
    else
    {
       locationSwitch.IsChecked = false;
    }
}
else
{
    MessageBoxResult result = MessageBox.Show("Allow this app to access your location?", "Location", MessageBoxButton.OKCancel);

    if (result == MessageBoxResult.OK)
    {
       IsolatedStorageSettings.ApplicationSettings["LocationConsent"] = true;
    }
    else
    {
       IsolatedStorageSettings.ApplicationSettings["LocationConsent"] = false;
    }
    IsolatedStorageSettings.ApplicationSettings.Save();
}

private void locationSwitch_Checked(object sender, RoutedEventArgs e)
{
    if (IsolatedStorageSettings.ApplicationSettings.Contains("LocationConsent"))
    {
       IsolatedStorageSettings.ApplicationSettings["LocationConsent"] = true;
       IsolatedStorageSettings.ApplicationSettings.Save();
    }
}

private void locationSwitch_Unchecked(object sender, RoutedEventArgs e)
{
   if (IsolatedStorageSettings.ApplicationSettings.Contains("LocationConsent"))
   {
      IsolatedStorageSettings.ApplicationSettings["LocationConsent"] = false;
      IsolatedStorageSettings.ApplicationSettings.Save();
   }
}

并且在您使用位置/GPS数据的页面上包含以下代码:

if ((bool)IsolatedStorageSettings.ApplicationSettings["LocationConsent"] == true)
{
     //Do Something
}
else
{
     MessageBox.Show("Please enable location services to use this feature. You can turn it on from Settings.");
}

这肯定会有帮助。我用的是一样的。如果这对您也有帮助，请点赞并标记为答案:)
