QLPreviewController and UIWebView do not display filled PDFs

I have a PDFthat has text boxes in it. My program uses Xfinium PDF software to fill the text boxes. When I view the filled in PDF the document shows up with no data in the fields. I have tried using QLPreviewController and UIWebView and they both do not display the filled in fields; however, if I email the document to myself and open it in Adobe DC on the iPad all the data shows up correctly. It may be important to note that even the mail app does not show the PDF correctly filled in. Here is the PDF opened in Adobe on iPad enter image description here Here is the PDF opened in UIWebView in my app (also shows same way in QLPreviewController enter image description here

Solution

  • PDF forms may bring along appearances or may rely on the viewer to create an appearance for the value of the field.

    Fairly complete PDF viewers (like Adobe Reader or Foxit) can get along with both variants well. Incomplete viewers, though, like many so called previewers, require an existing appearance and display empty documents for forms which do not bring along appearances.

    Thus, if you want your forms to be visible on incomplete viewers, too, provide appearances.
