When I try to use PDFDocument.init(url: ), I noticed that it worked with http but not with https URLs. Does anyone know why?
import PDFKit
let httpURL = URL(string: "http://www.axmag.com/download/pdfurl-guide.pdf")!
let doc1 = PDFDocument(url: httpURL) //makes a PDFDocument
let httpsURL = URL(string: "https://www.gnu.org/s/libmicrohttpd/tutorial.pdf")!
let doc2 = PDFDocument(url: httpsURL) //nil
@IBOutlet var pdfView: PDFView!
var pdfDOC: PDFDocument!
override func viewDidLoad() {
super.viewDidLoad()
downloadPDF()
}
func downloadPDF(){
let urlString = "https://www.tutorialspoint.com/swift/swift_tutorial.pdf"
guard let url = URL(string: urlString) else {return}
do{
let data = try Data(contentsOf: url)
pdfDOC = PDFDocument(data: data)
pdfView.displayMode = .singlePageContinuous
pdfView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
pdfView.displaysAsBook = true
pdfView.displayDirection = .vertical
pdfView.document = pdfDOC
pdfView.autoScales = true
pdfView.maxScaleFactor = 4.0
pdfView.minScaleFactor = pdfView.scaleFactorForSizeToFit
}catch let err{
print(err.localizedDescription)
}
}
