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

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 createdPDFView project. By this way, you can load and preview the local PDF document usingNSBundle. The following image shows an example of importing a PDF document namedOnline5 into the project.

   

2. Create aCPDFDocument object throughNSURL, and create aCPDFView to display it. The following code shows how to load PDF data using a local PDF path and display it byCPDFView.

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

3. Add the createdCPDFView 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:

   overridefunc viewWillAppear(_ animated:Bool){     super.viewWillAppear(animated)guardlet filePath=Bundle.main.path(forResource:"Online5", ofType:"pdf")else{return}leturl=URL(fileURLWithPath: filePath)letdocument=CPDFDocument(url: url)letrect=self.view.boundsletpdfView=CPDFView(frame:self.view.bounds)     pdfView.autoresizingMask=[.flexibleWidth,.flexibleHeight]     pdfView.document= documentself.view.addSubview(pdfView)}

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