Answer 1

If you want to share your pdf file which is on the server and you have a URL. Then first you download that file in your device and then share that file to any other person.
If you using Alamofire in your code then there is code.
Stape 1
import Alamofire
Stape 2
Add this function in your class:-
func downloadPdf(downloadUrl : String, fileName: String, completionHandler:#escaping(String, Bool)->()){
let destinationPath: DownloadRequest.DownloadFileDestination = { _, _ in
let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0];
let fileURL = documentsURL.appendingPathComponent("\(fileName).pdf")
return (fileURL, [.removePreviousFile, .createIntermediateDirectories])
}
print(downloadUrl)
Alamofire.download(downloadUrl, to: destinationPath)
.downloadProgress { progress in
}
.responseData { response in
print("response: \(response)")
switch response.result{
case .success:
if response.destinationURL != nil, let filePath = response.destinationURL?.absoluteString {
completionHandler(filePath, true)
}
break
case .failure:
completionHandler("", false)
break
}
}
}
Stape 3
Add this action on your share button
#IBAction func btnShareAction(_ sender: UIButton) {
let myURL = "http://www.demo.com/demo.pdf" // change this with your URL
self.downloadPdf(downloadUrl : myURL, fileName: "invoice") { (localFileUrl, bool) in
let fileURL = NSURL(fileURLWithPath: localFileUrl)
let activityViewController = UIActivityViewController(activityItems: [fileURL], applicationActivities: nil)
self.present(activityViewController, animated: true, completion: nil)
}
}

Simple Steps! Copy paste the give code
#objc private func btnShareTapped(_ sender: UIButton) {
guard let urlString = strURL,
let url = URL(string: urlString),
let docPath = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).last else {
return
}
let actualPath = docPath.appendingPathComponent("Statement.pdf")
let pdfData = try? Data.init(contentsOf: url)
do {
try pdfData?.write(to: actualPath, options: .atomic)
let fileURL = URL(fileURLWithPath: actualPath.absoluteString)
let activityVC = UIActivityViewController(activityItems: [fileURL],
applicationActivities: nil)
present(activityVC, animated: true)
} catch {
debugPrint("Pdf could not be saved")
}
}
