In SWIFT 4
#IBAction func sharePDF(_ sender: : Any) {
let fm = FileManager.default
var pdfURL = (fm.urls(for: .documentDirectory, in: .userDomainMask)).last! as URL
pdfURL = pdfURL.appendingPathComponent("GridLines.pdf") as URL
//Rename document name to "Hello.pdf"
let url = URL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent("Hello.pdf") as NSURL
do {
let data = try Data(contentsOf: pdfURL)
try data.write(to: url as URL)
let activitycontroller = UIActivityViewController(activityItems: [url], applicationActivities: nil)
if activitycontroller.responds(to: #selector(getter: activitycontroller.completionWithItemsHandler))
{
activitycontroller.completionWithItemsHandler = {(type, isCompleted, items, error) in
if isCompleted
{
print("completed")
}
}
}
activitycontroller.excludedActivityTypes = [UIActivityType.airDrop]
activitycontroller.popoverPresentationController?.sourceView = self.view
self.present(activitycontroller, animated: true, completion: nil)
}
catch {
//ERROR
}
}

You can also share the PDF data itself using the dataRepresentation() function
guard let data = document?.dataRepresentation() else { return }
let activityController = UIActivityViewController(activityItems: [data], applicationActivities: nil)
present(activityController, animated: true)

Try like this
let fileManager = FileManager.default
let docsurl = try! fileManager.url(for:.documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false)
let documentoPath = docsurl.appendingPathComponent("yourfile.pdf")
if fileManager.fileExists(atPath: documentoPath){
let pdfData = NSData(contentsOfFile: documentoPath)
var activityViewController = UIActivityViewController(activityItems: ["Your title that you wanna share", pdfData], applicationActivities: nil) // and present it
present(activityViewController, animated: true) {() -> Void in }
}
Its working fine ... I use it .

You already have a PDFDocument object, so reconstructing the file url is unnecessary. Simply pass your PDFDocument's documentURL property instead:
let activityVC = UIActivityViewController(activityItems: [self.pdfDocument!.documentURL!], applicationActivities: nil)

Answer 5

Try with this
let fileManager = FileManager.default
let docsurl = try! fileManager.url(for:.documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false)
let documentoPath = docsurl.appendingPathComponent("documento.pdf")
if fileManager.fileExists(atPath: documentoPath){
let documento = NSData(contentsOfFile: documentoPath)
let activityViewController: UIActivityViewController =
UIActivityViewController(activityItems: [documento!],
applicationActivities: nil)
activityViewController.popoverPresentationController?.sourceView=self.view
present(activityViewController, animated: true, completion: nil)
}
else {
print("document was not found")
}

Call this method on button click
func sharePdf() {
let activityViewController = UIActivityViewController(activityItems: [pdfView.document!.dataRepresentation()!], applicationActivities: nil)
present(activityViewController, animated: true)
}
For sharing image just change the activity item
func shareImg() {
let activityViewController = UIActivityViewController(activityItems: [imageView.image!], applicationActivities: nil)
present(activityViewController, animated: true)
}
You can share multiple items at once, by adding it in activityItems array
