I'm playing with CGPDFDocumentRef on iPad to read and write PDF's. While going through the CGPDFDocumentRef class reference, I found ways to read, search and create a PDF file. Thanks to stackover.com where I found more solutions to what I want.
But I would like to know how to append text or image at the end of PDF. Or some other instance like "fill in the blanks" where user will fill the blanks and saves it. On successfully saving the PDF, when its opened again, it must show the filled in blanks.
Is it possible? Can I achieve it with CGPDFDocumentRef or is there any 3rd party library?
