def_view = 3 or .PDFSetView(3) display all pages

I set configuration for instance of PDFReader to def_view = 3 or .PDFSetView(3) but still it displays all pages and I can scroll throw them. I need to show only one page from pdf. Pdf contains more pages than one

All the view settings will allow you to scroll throw all the pages.
The difference between them is the view mode, vertical, horizontal, dual,...etc.
