Implementing MailComposeController in tableView - ios

Question

I have created the setting page in TableView. When I tap row 0 UIActivityViewController is called. When I tap row2 MailComposeController is called.
MailComposeController is called, but when I tap cancel or send button on mail screen it does not work.
Here is the code。
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if indexPath.row == 0 {
let message = "Hey download my app [LINK]"
let shareView = UIActivityViewController(activityItems: [message], applicationActivities: nil)
self.present(shareView, animated: true, completion: nil)
} else if indexPath.row == 1 {
let mailCompose = MFMailComposeViewController()
mailCompose.mailComposeDelegate = self
mailCompose.setToRecipients(["address#gmail.com"])
mailCompose.setSubject("feedback")
mailCompose.setMessageBody("text", isHTML: false)
if MFMailComposeViewController.canSendMail()
{
self.present(mailCompose, animated: true, completion: nil)
}
else{
print("error...!")
}
}
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
controller.dismiss(animated: true, completion: nil)
}

Answer 1

You have to put the delegate method in the ViewController but not in the tableView:didSelectRowAt method:
extension ViewController: MFMailComposeViewControllerDelegate {
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
controller.dismiss(animated: true, completion: nil)
}
}

Answer 2

Implement the delegate methods of Mail composer on click of send and cancel button:
Here are the Delegates methods which you need to implement :
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
controller.dismiss(animated: true, completion: {
switch (result)
{
case .cancelled:
break
case .saved:
break;
case .sent:
AppUtility.showAlert(message: kEmailSentSuccessMessage, isSuccess: true)
break;
case .failed:
AppUtility.showAlert(message: kEmailSentFailureMessage, isSuccess: true)
break;
}
})
}
Use breakpoint to see what exactly going on the click of send or cancel. and make sure that you have created the MailComposer object locally . since this object is going to send and cancel the mail each time .
