Pdfkit example swift5/30/2023 PDFKitLinker also shows how to create and display a PDFOutline of the opened document. If the opened PDFDocument has an outline, PDFKitLinker will use the PDFOutline as data in an NSOutlineView and display it using NSTableView in an NSDrawer. That’s why this sample was written: at the time, links were the only game in town □ PDFAnnotationEditor is Apple’s flagship PDFKit sample program, but it was written for Leopard PDFAnnotationLink was the one interactive annotation that was properly implemented for Tiger. The destination of a link may be another page in the document or an external URL. This application enables the user to annotate a PDF document by embedding links or editing existing ones. PDFKitLinker2 2.0 presents many features of (Tiger) PDFKit. Unfortunately, though, PDFKitViewer does not support annotations. The UI has a search tool in the drawer above a Page/Section results list. Display of PDFOutline as data for NSOutlineView displayed using NSTableView in an NSDrawer.Basic use of PDFView with single page or side-by-side page display.PDFKitViewer demonstrates some simple and some less than simple uses of PDFKit: PDFKitViewer 2.0 illustrates the display of a PDF document. See the Read Me files in their project folders for details. They all work now-but some polish is still needed. So, I felt it would’ve been a shame to let these samples fade away! As an exercise, I’ve made them usable once more by updating their code from Tiger and Leopard to build and run in High Sierra. And macOS will be a direct beneficiary of that, giving me confidence that the framework, which had been allowed to stagnate will now receive true support. However, with the port to iOS-“PDFKit reloaded” (sorry, Keneau)-PDFKit has come into its own. And they’re incredibly well written-readable and well factored.īut through the accumulation of deprecated APIs over nine builds and, especially, the pervasive breakage in the macOS 10.13 High Sierra rewrite, they broke and faded into obscurity. Beyond PDFKit, they highlighted significant aspects of Cocoa. When I began using PDFKit, in the days of Tiger and Leopard, there were a number of sample apps that helped me learn the framework: PDFKitViewer, PDFKitLinker2, Link Snoop, PDFCalendar, PDFViewSubclasser, and PDFAnnotationEditor. These samples showed interesting aspects of PDFKit. You can then invoke the pdfData(actions:) of the renderer which provides you a block with the context that allows you to use drawing methods in CoreGraphics framework to start drawing texts or images etc, such as follows: let data = renderer.Through the vestiges of time, the “Lost PDFKit Samples” have been rediscovered and brought up to date! Let renderer = UIGraphicsPDFRenderer(bounds:pageRect, format: format) Let format = UIGraphicsPDFRendererFormat()įormat.documentInfo = pdfMetaData as To instantiate it, you need to specify its bounds and an optional parameter for its format, as follows: let pdfMetaData = [kCGPDFContextCreator: "My First PDF File", To create PDF file with the PDFKit, all you need is instantiate the key class UIGraphicsPDFRenderer in PDFKit framework. This is especially useful for apps that need to generate receipts, bills, invoices or any other confidential or important documents. PDF is useful so we can generate files that cannot be modified and shared or sent to others. PDFKit is the framework by Apple that you need to display and manipulate PDF files in your app.
