Getting Started

It's easy to embed ComPDFKit into an iOS application with a few lines of Swift or Objective-C code. Take a few minutes to get started.

The following sections explain how to run integration with Swift Package into your project

Requirements

ComPDFKit PDF SDK - Swift Package requires the latest stable version of Xcode available at the time the release was made. This is a hard requirement, as each version of Xcode is bundled with a specific version of the iOS Base SDK, which often defines how UIKit and various other frameworks behave.

• The iOS 10.0 or higher.
• The Xcode 13.0 or newer for Objective-C or Swift.

Display a PDF Document

So far, we have added "ComPDFKit.xcframework" to the "PDFViewer" project, and finished the initialization of the ComPDFKit PDF SDK. Now, let’s start building a simple PDF viewer with just a few lines of code.

1. Prepare a test PDF file, drag and drop it into the newly created PDFView project. By this way, you can load and preview the local PDF document using NSBundle. The following image shows an example of importing a PDF document named Online5 into the project.

   

2. Create a CPDFDocument object through NSURL, and create a CPDFView to display it. The following code shows how to load PDF data using a local PDF path and display it by CPDFView.

   guard let filePath = Bundle.main.path(forResource: "Online5", ofType: "pdf") else { return  }
   let url = URL(fileURLWithPath: filePath)
   let document = CPDFDocument(url: url)
   
   let rect = self.view.bounds
   let pdfView = CPDFView(frame: self.view.bounds)
   pdfView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
   pdfView.document = document

3. Add the created CPDFView to the view of the current controller. The sample code shows below.

   self.view.addSubview(pdfView)

   The code shown here is a collection of the steps mentioned above:

   override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
           
        guard let filePath = Bundle.main.path(forResource: "Online5", ofType: "pdf") else { return  }
        let url = URL(fileURLWithPath: filePath)
        let document = CPDFDocument(url: url)
   
        let rect = self.view.bounds
        let pdfView = CPDFView(frame: self.view.bounds)
        pdfView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        pdfView.document = document
        self.view.addSubview(pdfView)
   }

4. Connect your device or simulator, and use shortcut Command_R to run the App. The PDF file will be opened and displayed.
