Ive tried setting PDFView observers on page change when I scroll, saving that page to a local var and then calling pdfView.go(to: currentVisiblePage) etc to try and circumvent this but somehow the pdfView loses track of the correct page as the segmentedControl is tapped. tapping the segmentedControl again to go back to singlePageContinuous results in me still at the end of the document. I have tried saving the edited file to the same location as the unedited one.

the combination of pinching to zoom out, then tapping on the segmentedControl to change to say twoUpContinuous makes the pdfView lose track of the page within the document and it ends up showing me the last pages ie pages say 87,88,89, and 90 of the document. Creating a PDF in Swift with PDFKit Aug 26 2019, Swift 5, iOS 13, Xcode 11 Learn how to create a PDF, work with Core Text and Core Graphics and share the created document by building an app that displays the user’s input on a flyer that can be shared with other iOS apps.

The problem occurs when the pdf loads and I then pinch to zoom on the pdfView before tapping the segmentedControl to change displayMode. You can then ask for the page count, add or delete pages, perform a find, or parse selected. You initialize a PDFDocument object with PDF data or with a URL to a PDF file.
First of all, let’s start by creating a new single view application by clicking on XCode, and. In this tutorial, we are going to generate a cocktail menu using the public thecocktaildb API. I added a segmented control to the navigation bar with 2 segments which the user can tap to swap the pdfView displayMode from singlePageContinuous to twoUpContinuous and that works fine by itself too. The other utility classes are either instantiated from methods in PDFDocument, as are PDFPage and PDFOutline or support it, as do PDFSelection and PDFDestination. Generating PDFs Dynamically Using PDFKit in Swift Goals. Everything seems to be working fine re loading, viewing, scrolling, and navigating the document. This object handles formatting a document, especially when there is a need for page breaks. Create a project First, open Xcode, and create a new iOS App. In my own use of PDFKit Ive created the PDF text as an instance of NSMutableAttributedString (as you do), but then encapsulate that in an instance of UISimpleTextPrintFormatter.

I have a long 90 page pdf document as my test document. SwiftUI’s ability to quickly create UI is very powerful, and Apple also provides a PDFKit framework, so you can use SwiftUI and PDFKit to create a fully customizable PDF reader with very little code, very quickly.
I'm working on a PDF Viewer using new PDFKit in ios11. All will make an PDFKit framework available for use in the Swift file.
