(2 answers)
Closed 5 years ago.
my problem is that I programmed emailwindow and it does send emails, but when they are send or I want to close the window there´s nothing that happens.
Thats my code:
import Foundation
import UIKit
import MessageUI
class ContactViewController: UIViewController, MFMailComposeViewControllerDelegate, UIAlertViewDelegate {
override func viewDidLoad() {
super.viewDidLoad()
}
let mail = MFMailComposeViewController()
#IBAction func email(_ sender: Any) {
if !MFMailComposeViewController.canSendMail() {
let warnung = UIAlertController(title: "Email konnte nicht gesendet werden", message: "Dein Gerät unterstützt leider keine Email-Funktion.", preferredStyle: .alert)
let action1 = UIAlertAction(title: "OK", style: .default, handler: nil)
warnung.addAction(action1)
self.present(warnung, animated: true, completion: nil)
return
} else {
mail.mailComposeDelegate = self
mail.setToRecipients(["team#example.com"])
mail.setSubject("Message to you")
mail.setMessageBody("Hello,\n", isHTML: false)
present(mail, animated: true, completion: nil)
func mailComposeController(_ controller: MFMailComposeViewController,
didFinishWithResult result: MFMailComposeResult, error: NSError?) {
mail.dismiss(animated: true, completion: nil)
print("Yes!")
}
}
}
}
Here´s a screenshot of the mail window :
