Display PDF using PDFViewCTRL in Xamarin

The PTPDFViewCtrl is a UIView that displays a PDF.

If your app is displaying a PDF, a PTPDFViewCtrl will be used in one of two ways:

• Directly, by adding it as a subview to another view in your app.
• As a component piece of a PTDocumentController or PTTabbedDocumentViewController. (It is accessible via the pdfViewCtrl property.)

1. These instructions assume that you've initialized Apryse .

2. Add a PDF to your project:

   • Right click on Resources
   • Click on Add > Add Files
   • Choose a file (in this tutorial, let's say we added a sample.pdf) and confirm add
   • Make sure the Build Action of the file is set to BundleResource

3. Instantiate a new PDFDoc:

   var pdfPath = "sample.pdf";
   var docToOpen = new pdftron.PDF.PDFDoc(pdfPath);

4. Create a new PDFViewCtrl and add it as a child to the current view:

   // Create a new PDFViewCtrl
   var pdfViewCtrl = new pdftron.PDF.PDFViewCtrl();
   
   // Set the document to display
   pdfViewCtrl.Doc = TypeConvertHelper.ConvPDFDocToNative(docToOpen);
   
   // Add the PDFViewCtrl to the current view controller's root view.
   View.AddSubview(pdfViewCtrl);
   
   // Auto Layout
   pdfViewCtrl.TranslatesAutoresizingMaskIntoConstraints = false;
   NSLayoutConstraint.ActivateConstraints(new NSLayoutConstraint[] {
       pdfViewCtrl.LeadingAnchor.ConstraintEqualTo(this.View.LeadingAnchor),
       pdfViewCtrl.WidthAnchor.ConstraintEqualTo(this.View.WidthAnchor),
       pdfViewCtrl.TopAnchor.ConstraintEqualTo(this.View.LayoutMarginsGuide.TopAnchor),
       pdfViewCtrl.BottomAnchor.ConstraintEqualTo(this.View.BottomAnchor)
   });

   Running the app will now display the PDF sample.pdf. However, it will not support annotation creation, editing, text selection, or any other UI aspect that is handled by Tools package . To add support for annotations and text selection you need to incorporate the tools package .
