![]() ![]() Configuring the ContextĪs a next step, we are going to implement a function that takes a cocktail, extracts all the relevant information, and using the previous extensions, adds it to the context. After doing so, we use the function 4 ( checkContext()) that will check if our text is exceeding the bounds of the page, and if so, start a new page dynamically and reset the cursor.įinally, the function 5 calculates the height of a multi-line sentence, so that we know where the text ends and where to start the next paragraph. We then use the indent and Page Size parameters to place our string in a CGRect described by the function definition (centered, single line left aligned, and multi-line left aligned). In the implementation of functions 1, 2 and 3, attributes are assigned to our text in an Attributed String variable. A few resources to get you started if this is your first SwiftUI project: 100 days of SwiftUI Apple SwiftUI. Getting ready Let's create a new SwiftUI app in Xcode called PDFReaderApp. As you can imagine, PDFKit is based on UIKit however, in this recipe, we'll see how easy it is to integrate it with SwiftUI. This project is a starting point for a SwiftUI application. Showing a PDF in SwiftUI Since iOS 11, Apple has provided PDFKit, a robust framework to display and manipulate PDF documents in your applications. ![]() ![]() The final result is as shown below: Getting Started. Session App Frameworks WWDC17 Introducing PDFKit on ios PDF on 13 PDFKit Framework Here is sample code which demonstrates the counterrotation: Swift The. These methods are added as an extension to UIGraphicsPDFRendererContext, which is the context that is going to render our PDF.Īll we have to do is dictate to the context everything we need our PDF to have (PDF metadata, PDF dimensions, page breaks, and of course the text we are going to present on the document). Sample code for rendering PDF documents using Apple's PDFKit in SwiftUI. ![]()
