Xamarin.ios寻求权限的适当位置

Question

我需要使用Xamarin.Essentials在Xamarin.iOS应用程序中请求权限。到目前为止，我发现的所有示例都是关于Xamarin.Forms的，我没有使用过。]

到目前为止，我发现的所有示例都是关于在按下按钮时询问权限，这对于实验来说是很好的，但对于生产应用程序来说是没有用的。

我有以下异步代码：

// TODO Move the permission requests to a more appropriate location?
var status = await Permissions.CheckStatusAsync<Permissions.Camera>();

if (status != PermissionStatus.Granted)
{
    status = await Permissions.RequestAsync<Permissions.Camera>();
}
status = await Permissions.CheckStatusAsync<Permissions.Microphone>();
{
    status = await Permissions.RequestAsync<Permissions.Microphone>();
}
我是从ViewDidLoad异步替代调用它的。每当我调用Permissions.RequestAsync（）

时，应用程序就会崩溃并显示以下输出

我的info.plist包含有关权限的以下内容：

<key>NSCameraUsageDescription</key>
<string>L&apos;accès est réservé au vidéoconférences.</string>
<key>NSMicrophoneUsageDescription</key>
<string>L&apos;accès est réservé au vidéoconférences.</string>
必须有适当的位置才能安全地调用此编码，但我不知道。

感谢任何帮助。

我需要在具有Xamarin.Essentials的Xamarin.iOS应用程序中请求权限。到目前为止，我发现的所有示例都与我未使用的Xamarin.Forms有关。到目前为止，我已经找到的所有样本...

您不需要iOS的特定代码。这就是Essentials
