Sending Email through your app in Swift
Posted By : Akshay Luthra | 18-Dec-2015
First of all, we need to import the MessageUI module.
Second, we need to specify that the View Controller will conform to the MFMailComposeViewControllerDelegate protocol.
In order to send Email through your app in Swift, you need a few things :
1. A View Controller from which the user will initiate the display of the email composer screen, say by tapping on a button.
@IBAction func sendEmailButtonTapped(sender: AnyObject) {
// Logic to send the Email goes here
}
2. A configured MFMailComposeViewController to present.
func configuredMailComposeViewController() -> MFMailComposeViewController {
let mailComposerVC = MFMailComposeViewController()
mailComposerVC.mailComposeDelegate = self
mailComposerVC.setToRecipients([])
mailComposerVC.setSubject("Sending In-App Email")
mailComposerVC.setMessageBody("Sending Email through your app in Swift", isHTML: false)
return mailComposerVC
}
3. A MFMailComposeViewControllerDelegate to handle dismissing the email composer screen.
func mailComposeController(controller: MFMailComposeViewController!, didFinishWithResult result: MFMailComposeResult, error: NSError!) {
controller.dismissViewControllerAnimated(true, completion: nil)
}
The whole Swift code for sending Email through your app :
import Foundation
import UIKit
import MessageUI
class ViewController: UIViewController, MFMailComposeViewControllerDelegate {
override func viewDidLoad() {
super.viewDidLoad()
}
@IBAction func sendEmailButtonTapped(sender: AnyObject) {
let mailComposeViewController = configuredMailComposeViewController()
if MFMailComposeViewController.canSendMail() {
self.presentViewController(mailComposeViewController, animated: true, completion: nil)
} else {
self.showSendMailErrorAlert()
}
}
func configuredMailComposeViewController() -> MFMailComposeViewController {
let mailComposerVC = MFMailComposeViewController()
mailComposerVC.mailComposeDelegate = self
mailComposerVC.setToRecipients([])
mailComposerVC.setSubject("Sending In-App Email")
mailComposerVC.setMessageBody("Sending Email through your app in Swift", isHTML: false)
return mailComposerVC
}
func showSendMailErrorAlert() {
let sendMailErrorAlert = UIAlertView(title: "Could Not Send Email", message: "Your device could not send Email. Please check Email configuration and try again.", delegate: self, cancelButtonTitle: "OK")
sendMailErrorAlert.show()
}
// MFMailComposeViewControllerDelegate Method
func mailComposeController(controller: MFMailComposeViewController!, didFinishWithResult result: MFMailComposeResult, error: NSError!) {
controller.dismissViewControllerAnimated(true, completion: nil)
}
}
