Activity controller adding subject to mail swift
In Swift, you can add a subject to an email using the Mail
framework and an ActivityController
. Here's an example:
import UIKit
import MessageUI
class ViewController: UIViewController, MFMailComposeViewControllerDelegate {
let mailController = MFMailComposeViewController()
override func viewDidLoad() {
super.viewDidLoad()
// Set up the mail controller
mailController.mailComposeDelegate = self
mailController.setSubject("Your Subject")
// Add recipients, body, etc.
}
func sendEmail() {
// Present the mail controller
present(mailController, animated: true, completion: nil)
}
// MARK: - MFMailComposeViewControllerDelegate
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
// Dismiss the mail controller
controller.dismiss(animated: true, completion: nil)
}
}
In this example, we create an instance of MFMailComposeViewController
and set its mailComposeDelegate
to self
. We then set the subject of the email using the setSubject(_:)
method.
To present the mail controller, we call the sendEmail()
method, which presents the mail controller modally.
In the mailComposeController(_:didFinishWith:erro:)
method, we dismiss the mail controller when the user finishes composing the email.
Note that you need to import the MessageUI
framework and conform to the MFMailComposeViewControllerDelegate
protocol to use the MFMailComposeViewController
class.
Also, make sure to add the MessageUI
framework to your target in your project settings.
