It’s a subclass of UIView, and its main purpose is to display a PDF Document. Note: In this tutorial, I’m going to build an iPad app, but PDFKit also works for iPhone.
IOS PDFKIT PDFVIEW ADD AS SUBVIEW HOW TO
Looks easy, doesn’t it? We don’t need to teach you how to use Alamofire for downloading and uploading files - we’ll go straight to PDFKit. Save a PDF document and upload it to the server.Add ink annotations to a PDF with the user’s finger or an Apple pencil.View a PDF document and allow the user to navigate between pages.However, there were no major changes in PDFKit framework since iOS 13. This tutorial was updated to iOS 15, you’ll also find some useful information about PencilKit, PKCanvasView and PKToolPicker introduced with iOS 13 in the second part, as well as how to add text annotations. We also found a few bugs, which lead to crashes (inside the Framework), and lack of documentation and tutorials or examples. However, I’d spent a lot of time making drawings, touches, and annotations work as expected. It actually seems to be "magical" framework to solve our task in just a few lines of code. It includes views for PDF documents and thumbnails with built-in gestures support and lot of animations.
Of course, we understood it wouldn’t be an easy task, but we never imagined quite how challenging it would be.Īt first sight, PDFKit looks like any other Apple’s framework included in iOS SDK. The key feature of this viewer was the ability to add annotations to a PDF file with a finger or Apple Pencil. My team recently started a new project: to develop a new iOS app with a built-in PDF Viewer. The third article is about creating PDF document on devices, and inserting and removing pages.The second is about PencilKit, Text annotations and auto-saving.We’ll start with PDFKit basics and will create first Ink annotations in the end of this tutorial. This is my first article about Apple’s PDFKit.
