![]() Start by adding PKCanvasView to the starter app. For example, you can pre-select PKInkingTool to draw lines on a canvas view. This may make users very sad, but hey, whatever makes sense for your app. You may choose not to present a picker and instead pre-select the tools available for drawing. Users can pick which tool they want to use. The tool picker contains the artist’s brushes, pens, ink, paint and other required drawing tools. ![]() PKCanvasView can present a tool picker to the user. PKCanvasView is a subclass of UIScrollView, so it allows bounds that are larger than the visible area. It captures Apple Pencil input and presents it on the screen. The PencilKit equivalent is PKCanvasView. Rendition: Your rendition’s data model, which will host your drawing data.Īny good artist knows that you typically draw on a canvas.DrawingView: Where the drawing (magic) happens.Take a look at the key files in MasterThis to familiarize yourself with the project: You’ll be adding functionality to turn that empty black hole into a canvas fit for Picasso. Fortunately, you’re an iOS developer and a super hero so you should be ready to go. ![]() However, the app’s not quite ready for you. Tap anywhere outside the pop-up to dismiss it and get ready to draw. Tap + in the top left to show the list of masterpieces available for you to practice drawing with. You should see a blank screen waiting for you to unleash your creative brilliance: Now, open MasterThis.xcodeproj in the starter folder. Once satisfied, you can share your rendition with future admirers.Ĭlick the Download Materials button at the top or bottom of this tutorial to download the starter project. The sample app lets you flex your artistic side as you practice drawing masterpieces. In this tutorial, you’ll learn the basics of PencilKit by building out MasterThis. These combine to make PencilKit the de facto choice for creating drawing apps. ![]() These include different brush types, an eraser and a lasso selection tool. PencilKit provides a rich palette to help users pick the right tools for drawing. Drawing with it feels fluid and responsive. Low latency and efficient drawing are two highlights of PencilKit. PencilKit allows you to easily build apps that create drawings or annotate documents. Before iOS 13, integrating Apple Pencil was more complicated. 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.Apple introduced PencilKit in iOS 13, making it easy to use Apple Pencil to add drawing features to iOS apps. 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.
