Send mail with file attachment

Question

I search solution to send a mail with attachment. I have this code but the file is not attached...

if let url = URL(string: "mailto:\(email)?subject=report&body=see_attachment&attachment=/Users/myname/Desktop/report.txt") {
    NSWorkspace.shared().open(url)
}

I have see it maybe work with MessageUI, but I can't import this framework I don't know why. I get this error message : No such module 'MessageUI' I checked in General > Linked Frameworks and Libraries, but there are not MessageUI...

Anyone have a solution to add file in mail? Thanks

Answer 1

It seems that attachment in mailto: URLs are not supported on macOS (not always at least...details seems sketchy dependent on where you look on the internet :))

What you can use instead I found out from this blog post, is an instance of NSSharingService documented here

Here is an example demonstrating how to use it.

And in your case you could do something like:

let email = "your email here"
let path = "/Users/myname/Desktop/report.txt"
let fileURL = URL(fileURLWithPath: path)

let sharingService = NSSharingService(named: NSSharingServiceNameComposeEmail)
sharingService?.recipients = [email] //could be more than one
sharingService?.subject = "subject"
let items: [Any] = ["see attachment", fileURL] //the interesting part, here you add body text as well as URL for the document you'd like to share

sharingService?.perform(withItems: items)

Hope that helps you.

import MessageUI
class ViewController: UIViewController,MFMailComposeViewControllerDelegate {

func sendMail() {
  if( MFMailComposeViewController.canSendMail()){
        print("Can send email.")

        let mailComposer = MFMailComposeViewController()
        mailComposer.mailComposeDelegate = self

        //Set to recipients
        mailComposer.setToRecipients(["[e-mail]"])

        //Set the subject
        mailComposer.setSubject("email with document pdf")

        //set mail body
        mailComposer.setMessageBody("This is what they sound like.", isHTML: true)
        let pathPDF = "\(NSTemporaryDirectory())contract.pdf"
            if let fileData = NSData(contentsOfFile: pathPDF) 
            {
                print("File data loaded.")
                mailComposer.addAttachmentData(fileData as Data, mimeType: "application/pdf", fileName: "contract.pdf")
            }

        //this will compose and present mail to user
        self.present(mailComposer, animated: true, completion: nil)
    }
    else
    {
        print("email is not supported")
    }

  func mailComposeController(_ didFinishWithcontroller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?)
  {
    self.dismiss(animated: true, completion: nil)
  }
}

First of all you should import import MessageUI. For this add framework to the project.

Example:

After investigate MFMailComposeViewControllerDelegate for knowing when you end sending email.

Example of the creating of the email:

if( MFMailComposeViewController.canSendMail() ) {
        println("Can send email.")

        let mailComposer = MFMailComposeViewController()
        mailComposer.mailComposeDelegate = self

        //Set the subject and message of the email
        mailComposer.setSubject("Have you heard a swift?")
        mailComposer.setMessageBody("This is what they sound like.", isHTML: false)

        if let filePath = NSBundle.mainBundle().pathForResource("swifts", ofType: "wav") {
            println("File path loaded.")

            if let fileData = NSData(contentsOfFile: filePath) {
                println("File data loaded.")
                mailComposer.addAttachmentData(fileData, mimeType: "audio/wav", fileName: "swifts")
            }
        }
        self.presentViewController(mailComposer, animated: true, completion: nil)
    }
