SfPdfViewer does not work for a project Xamarin.Forms iOS

Hello

I'm using the PDF viewer for a Xamarin.Forms project on Android and iOS.

The PDF display works great on Android, but on iOS, whether on an emulator, an iPad or an iPhone, the display does not work and the page remains blank.

Of course, I instantiate the SfPdfDocumentViewRenderer class in the AppDelegate file. I even try the static Init method of the SfPdfDocumentViewRenderer class ... but nothing works!

Did I forget to initialize something?

Best Regards

M. BINET Julien

Hello,

Thank you for your answer !

Following your example, I was able to solve my problem on iOS :)

The problem was that the SfPdfViewer control was in a StackLayout container, replacing it with a Grid container, the problem was solved.

Hi Julien, 

Thanks for your update. 

If you need to use the PDF Viewer inside a StackLayout in Xamarin Forms iOS, We need to set the VerticalOptions and HorizontalOptions property of the PDF Viewer control to “FillAndExpand”. 

Please refer the below code snippet to use the PDF Viewer inside the StackLayout in Xamarin Forms iOS. 
<StackLayout x:Name="pdfViewGrid" > 
        <syncfusion:SfPdfViewer x:Name="pdfViewerControl" InputFileStream="{Binding PdfDocumentStream}" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand"/> 
</StackLayout> 

We have created a simple sample by using the above code snippet and please find the sample from the below link. 

Please refer the output screenshot from the below link 

Please let us know if you have any concerns. 

Regards, 
Kathiravan E
