Cómo establecer a los destinatarios con MFMailComposeViewController

Question

Estoy tratando de recibir los correos electrónicos que selecciono para enviar un correo electrónico. Pero no sé cómo configurar los usuarios que he seleccionado en la vista MFMailComposeViewController.

if ([MFMailComposeViewController canSendMail]) 
    { 
     mailer = [[MFMailComposeViewController alloc] init]; 

     mailer.mailComposeDelegate = self; 
     [mailer setSubject:@"A Message from blablabl"]; 

     NSMutableArray *usersTo = [[NSMutableArray alloc] init]; 
     toRecipients = usersTo; 
     [mailer setToRecipients:toRecipients]; 

     NSString *emailBody = @"blablablabal"; 

     [mailer setMessageBody:emailBody isHTML:YES]; 

     // only for iPad 
     // mailer.modalPresentationStyle = UIModalPresentationPageSheet; 

     [self presentModalViewController:mailer animated:YES]; 
    } 
    else 
    { 
     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Failure" 
                 message:@"Your device doesn't support the composer sheet" 
                 delegate:nil 
               cancelButtonTitle:@"OK" 
               otherButtonTitles: nil]; 
     [alert show]; 
    }

Answer 1

un par de cosas están mal aquí.

1)

método de MFMailComposeViewController setToRecipients espera una matriz inmutable con los receptores ya establecido.

2)

Y se está configurando a una matriz mutable en blanco.

intentar algo como esto:

NSArray *usersTo = [NSArray arrayWithObject: @"nobody@stackoverflow.com"]; 
[mailer setToRecipients:usersTo]; 

Y hay que ver que funcione.

Answer 2

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; 
    NSArray *toRecipients = [NSArray arrayWithObjects:@"first@gmail.com",@"second@gmail.com",nil]; 
    [picker setToRecipients:toRecipients];

MFMailComposer In “ Swift “ and “ Objective c “ 
********************************************* 
In objective c 
Steps: 
1. Create new project. 
2. Add a button into storyboard. 
3. In .h add header file like “Import <MessageUI/MessageUI.h>” 
4. Add delegate to ViewController “ MFMailComposeViewControllerDelegate” 

5. In Button Action  { 
          NSString *emailTitle = “” 
          NSString *messageBody = “” 
          NSArray *toRecipents = “”         
          MFMailComposeViewController *VC = [[MFMailComposeViewController]alloc init]; 
          VC.mailComposeDelegate = self; 
          [VC.setSubject: emailTitle]; 
          [VC.setMessageBody: messageBody]; 
          [VC.setToRecepents: toRecipents]; 
      if([MFMailComposeViewController canSendMail]) { 
       [self presentViewController:mc animated:YES completion:NULL]; 
      } 

6.MailComposeController Function 

     - (void) mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error 
{ 
    switch (result) 
    { 
     case MFMailComposeResultCancelled: 
      NSLog(@"Mail cancelled"); 
      break; 
     case MFMailComposeResultSaved: 
      NSLog(@"Mail saved"); 
      break; 
     case MFMailComposeResultSent: 
      NSLog(@"Mail sent"); 
      break; 
     case MFMailComposeResultFailed: 
      NSLog(@"Mail sent failure: %@", [error localizedDescription]); 
      break; 
     default: 
      break; 
    } 
    [self dismissViewControllerAnimated:YES completion:NULL]; 
} 

7. And also add FrameWork: MessageUI.FrameWork 

8. Run the App into mobile or Simulator.  




In Swift: 
******* 
Steps: 
1. Create New Project 

2. Add a button Storyboard 

3. In ViewController.Swift Class File Import MessageUI 

4. In Button Action ConfiguredMailComposer below Steps 
     { 
     let mailComposeViewController = configuredMailComposeViewController() 

     if MFMailComposeViewController.canSendMail() 
{ 
      self.present(mailComposeViewController, animated: true, completion: nil) 
      self.showSendmailSuccesfulAlert() 
     } else { 

      self.showSendMailErrorAlert() 

     } 
5. Implement the configure mail composer 

     func configuredMailComposeViewController() -> MFMailComposeViewController { 

     let mailComposerVC = MFMailComposeViewController() 
     mailComposerVC.mailComposeDelegate = self 
     mailComposerVC.setToRecipients(["someone@somewhere.com"]) 
     mailComposerVC.setSubject("Sending you an in-app e-mail...") 
     mailComposerVC.setMessageBody("Sending e-mail in-app is not so bad!", isHTML: false) 
     return mailComposerVC 

    } 

6. MailComposer optional method 

     func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) { 

     controller.dismiss(animated: true, completion: nil) 

    } 

7. After completed the step no: run the app into device or simulator.
