MFMailComposeViewController does not dismiss - ios

Question

I'm trying to implement MFMailComposeViewController in case of sending the emails from within my application. The problem is that after presenting MFMailComposeViewController it is not dismissing by "Cancel" or "Send" buttons, just a bit scrolls up.
Here is the presenting of it:
func mailButtonDidPressed {
let emailTitle = "Test email"
let messageBody = "some body bla bla bla"
let toRecipents = "email#gmail.com"
let emailComposer = MFMailComposeViewController()
emailComposer.setSubject(emailTitle)
emailComposer.setMessageBody(messageBody, isHTML: false)
emailComposer.setToRecipients([toRecipents])
emailComposer.mailComposeDelegate = self
self.presentViewController(emailComposer, animated: true, completion: nil)
}
and dismissing delegate code:
func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?) {
switch (result) {
case MFMailComposeResultSent:
print("You sent the email.")
break
case MFMailComposeResultSaved:
print("You saved a draft of this email")
break
case MFMailComposeResultCancelled:
print("You cancelled sending this email.")
break
case MFMailComposeResultFailed:
print("Mail failed: An error occurred when trying to compose this email")
break
default:
print("An error occurred when trying to compose this email")
break
}
controller.dismissViewControllerAnimated(true, completion: nil)
}
I have surfed through the StackOverflow and other services like this and could not find any answer.

Answer 1

Swift 5
Remember to add both delegates:
emailComposer.mailComposeDelegate = self
emailComposer.delegate = self
If you only add one, it won't dismiss. Also make sure to implement the delegate method:
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
dismiss(animated: true)
}

Answer 2

If anybody's having this problem in Swift 3.0, I think there might be two methods for MFMailComposeViewController that look similar to the CORRECT method.
Make sure you are using this method
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
controller.dismiss(animated: true, completion: nil)
}

Answer 3

for swift 3 you have to add
composer.mailComposeDelegate = self as MFMailComposeViewControllerDelegate

Answer 4

I solved writing in this way removing the completion in this way:
extension UIViewController: MFMailComposeViewControllerDelegate {
func sendEmail() {
//send email
}
public func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
controller.dismiss(animated: true)
}
}

Answer 5

Assuming mailComposeControllermailComposeControlleris a function of the same class as mailButtonDidPressedmailButtonDidPressed, it should be its instance that dismiss the MFMailComposeViewController, so
self.dismissViewControllerAnimated(true, completion: nil)
instead of
controller.dismissViewControllerAnimated(true, completion: nil)

Answer 6

You didn't add the delegate :
emailComposer.delegate = self
your code should be like this :
func mailButtonDidPressed {
...
let emailComposer = MFMailComposeViewController()
emailComposer.delegate = self
...
}

I had this problem and the answer was extremely simple. Make sure to include
MFMailComposeViewControllerDelegate
in the top as when you are listing your inheritances, and then include the stuff from the other answers.
