How can I add a PDF file for an app , where you click on a button to view the file & when you\'re done you get back to screen you were at?
You can use this code in Swift 4
Copy this code
let pdfView = PDFView()
pdfView.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(pdfView)
pdfView.leadingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leadingAnchor).isActive = true
pdfView.trailingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.trailingAnchor).isActive = true
pdfView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor).isActive = true
pdfView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor).isActive = true
guard let path = Bundle.main.url(forResource: "test", withExtension: "pdf") else { return }
if let document = PDFDocument(url: path) {
pdfView.document = document
}
