Question

I want to send email with a PDF attachment. I created PDF file, then I did the following which is wrong I believe:

// locate folder containing pdf file               


        

Answer 1

First one, import:

import MessageUI

And implement de Email Delegate, like

public class MyViewController : UIViewController, MFMailComposeViewControllerDelegate { ...

If you have the file or the Data type, you can use this function:

let filePath = NSBundle.mainBundle().pathForResource("chart", ofType: "pdf")
let fileData = NSData(contentsOfFile: filePath)
sendEmail(data:fileData)

Swift 4

func sendEmail(data:Data?){
    if( MFMailComposeViewController.canSendMail() ) {
        let mailComposer = MFMailComposeViewController()
        mailComposer.mailComposeDelegate = self

        mailComposer.setToRecipients(["john@stackoverflow.com", "mrmins@mydomain.com", "anotheremail@email.com"])
        mailComposer.setSubject("Cotización")
        mailComposer.setMessageBody("My body message", isHTML: true)

        if let fileData = data {
            mailComposer.addAttachmentData(fileData, mimeType: "application/pdf", fileName: "MyFileName.pdf")
       }


       self.present(mailComposer, animated: true, completion: nil)
            return
    }
    print("Email is not configured")

}

And the compose:

public func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?){
        self.dismiss(animated: true, completion: nil)
        print("sent!")
    }
