![]() ![]() So in this article I’ll write about PDF specific stuff as the image gallery was a better example of how to scroll views efficiently. I wrote about scrolling images in a UIScrollView in another post Let’s start with the UIScrollView containing views with single PDF pages.Īs I mentioned before this was the solution I had to implement a few years ago, I cut some corners for the Swift porting as I don’t expect to use this in production now that iOS supports it in the framework. Using a Webview is so simple I didn’t feel the need to write the example, I’m sure there are tons of them available. Where I put two implementations: the scrollview with PDF pages and the one with PDFView. Recently I wanted to port my Objective-C code to Swift and I decided to share the implementation, so I created this GitHub project I started working on the custom solution back when we didn’t have WKWebViews nor PDF Kit, so my only alternatives were displaying PDFs in a UIWebView or implementing a custom solution. 2022 Deprecated in favor of PDFKIT for iOS 11+ apps iOS-PDF-Reader PDF. The third alternative is drawing PDF pages and place them on a UIScrollView. Note: In this example, note that the CSS is slightly different from the one. In iOS 11 Apple introduced a new class PDFView, a subclass of UIView that comes with a configuration, so you can have side-by-side pages, vertical and horizontal scrolling and many more options. I said we have 3 ways to show the PDF and we just saw one, so what are the remaining two? ![]() The only downside is the scrolling is only vertical, which is fine for most apps but you may want to provide some customisations, for example the ability to scroll horizontally and to have two pages side-by-side in landscape. Save In the article, I will discuss, how we can create PDF programmatically using the PDFKit framework. Mobikul Marketing Android Build Flutter iOS React Native Support UI Create PDF view programmatically using PDFKit in swift. Just like loading a local page, or a remote one, you can provide the URL of the PDF and the WKWebView will take care of it. PDFKit provides option to add annotation to PDF file using PDFAnnoation class. Create PDF view programmatically using PDFKit in swift. There are three possible ways of displaying a PDF. It could be a privacy policy document, an invoice, a flyer the company distributes on paper and via its app, a magazine. 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.Showing PDFs is pretty common for an iOS app. ![]() 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. There are few simple UIKit methods for that. We'll take you through the latest features in PDFKit, including support for live text and forms, creating PDFs from images, building interactive overlays, and saving annotations. This is especially useful for apps that need to generate receipts, bills, invoices or any other confidential or important documents. Create PDF Document using Swift In case you need to create a new PDF file on iOS device you won’t actually need to use PDFKit at all. Discover PDFKit a full-featured framework that helps your app view, edit, and save PDF 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. ![]()
