How can I launch an email client on ios using Swfit

Question

In Android, I can launch an email client from my android application using its Intent mechanism. In ios, how can I launch its email client from my ios application using Swif

Answer 1

SWIFT 3: The openEmail function will try to use the iOS Mail app if it is available (user has atleast one email account setup). Otherwise it will use the mailto: url (see full example at the bottom of my reply) to launch a mail client.

import MessageUI
// Make your view controller conform to MFMailComposeViewControllerDelegate
class Foo: UIViewController, MFMailComposeViewControllerDelegate {

    func openEmail(_ emailAddress: String) {
        // If user has not setup any email account in the iOS Mail app
        if !MFMailComposeViewController.canSendMail() {
            print("Mail services are not available")
            let url = URL(string: "mailto:" + emailAddress)
            UIApplication.shared.openURL(url!)
            return
        }

        // Use the iOS Mail app
        let composeVC = MFMailComposeViewController()
        composeVC.mailComposeDelegate = self
        composeVC.setToRecipients([emailAddress])
        composeVC.setSubject("")
        composeVC.setMessageBody("", isHTML: false)

        // Present the view controller modally.
        self.present(composeVC, animated: true, completion: nil)
    }

    // MARK: MailComposeViewControllerDelegate
    func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
        // Dismiss the mail compose view controller.
        controller.dismiss(animated: true, completion: nil)
    }
}

An all out mailto example with subject, body, and cc:

"mailto:me@gmail.com?subject=Hey whats up man!&body=This is from a great example I found online.&cc=someoneelse@yahooo.com&bcc=whostillusesthis@hotmail.com"
