C# 如何使用Zxing.Mobile向xamarin forms IOS应用程序添加条形码Sanning功能

我需要将扫描功能添加到现有的移动应用程序中。应用程序将使用zxing.mobile包扫描条形码

for xamarin forms
var scanPage = new ZXingScannerPage ();
// Navigate to our scanner page
await Navigation.PushAsync (scanPage);



scanPage.OnScanResult += (result) => 
{
    // Stop scanning
    scanPage.IsScanning = false;

    // Pop the page and show the result
    Device.BeginInvokeOnMainThread (async () => 
    {
        await Navigation.PopAsync ();        
        await DisplayAlert("Scanned Barcode", result.Text, "OK");
    });
};
