How can I send mail from an iPhone application

Question

I want to send an email from my iPhone application. I have heard that the iOS SDK doesn\'t have an email API. I don\'t want to use the following code because it will exit my

Answer 1

On iOS 3.0 and later you should use the MFMailComposeViewController class, and the MFMailComposeViewControllerDelegate protocol, that is tucked away in the MessageUI framework.

First add the framework and import:

#import <MessageUI/MFMailComposeViewController.h>

Then, to send a message:

MFMailComposeViewController* controller = [[MFMailComposeViewController alloc] init];
controller.mailComposeDelegate = self;
[controller setSubject:@"My Subject"];
[controller setMessageBody:@"Hello there." isHTML:NO]; 
if (controller) [self presentModalViewController:controller animated:YES];
[controller release];

Then the user does the work and you get the delegate callback in time:

- (void)mailComposeController:(MFMailComposeViewController*)controller  
          didFinishWithResult:(MFMailComposeResult)result 
                        error:(NSError*)error;
{
  if (result == MFMailComposeResultSent) {
    NSLog(@"It's away!");
  }
  [self dismissModalViewControllerAnimated:YES];
}

Remember to check if the device is configured for sending email:

if ([MFMailComposeViewController canSendMail]) {
  // Show the composer
} else {
  // Handle the error
}

Swift 2.2. Adapted from Esq's answer

import Foundation
import MessageUI

class MailSender: NSObject, MFMailComposeViewControllerDelegate {

    let parentVC: UIViewController

    init(parentVC: UIViewController) {
        self.parentVC = parentVC
        super.init()
    }

    func send(title: String, messageBody: String, toRecipients: [String]) {
        if MFMailComposeViewController.canSendMail() {
            let mc: MFMailComposeViewController = MFMailComposeViewController()
            mc.mailComposeDelegate = self
            mc.setSubject(title)
            mc.setMessageBody(messageBody, isHTML: false)
            mc.setToRecipients(toRecipients)
            parentVC.presentViewController(mc, animated: true, completion: nil)
        } else {
            print("No email account found.")
        }
    }

    func mailComposeController(controller: MFMailComposeViewController,
        didFinishWithResult result: MFMailComposeResult, error: NSError?) {

            switch result.rawValue {
            case MFMailComposeResultCancelled.rawValue: print("Mail Cancelled")
            case MFMailComposeResultSaved.rawValue: print("Mail Saved")
            case MFMailComposeResultSent.rawValue: print("Mail Sent")
            case MFMailComposeResultFailed.rawValue: print("Mail Failed")
            default: break
            }

            parentVC.dismissViewControllerAnimated(false, completion: nil)
    }
}

Client code :

var ms: MailSender?

@IBAction func onSendPressed(sender: AnyObject) {
    ms = MailSender(parentVC: self)
    let title = "Title"
    let messageBody = "https://stackoverflow.com/questions/310946/how-can-i-send-mail-from-an-iphone-application this question."
    let toRecipents = ["foo@bar.com"]
    ms?.send(title, messageBody: messageBody, toRecipents: toRecipents)
}

To send an email from iPhone application you need to do below list of task.

Step 1: Import #import <MessageUI/MessageUI.h> In your controller class where you want to send an email.

Step 2: Add the delegate to your controller like shown below

 @interface <yourControllerName> : UIViewController <MFMessageComposeViewControllerDelegate, MFMailComposeViewControllerDelegate>

Step 3: Add below method for send email.

 - (void) sendEmail {
 // Check if your app support the email.
 if ([MFMailComposeViewController canSendMail]) {
    // Create an object of mail composer.
    MFMailComposeViewController *mailComposer =      [[MFMailComposeViewController alloc] init];
    // Add delegate to your self.
    mailComposer.mailComposeDelegate = self;
    // Add recipients to mail if you do not want to add default recipient then remove below line.
    [mailComposer setToRecipients:@[<add here your recipient objects>]];
    // Write email subject.
    [mailComposer setSubject:@“<Your Subject Here>”];
    // Set your email body and if body contains HTML then Pass “YES” in isHTML.
    [mailComposer setMessageBody:@“<Your Message Body>” isHTML:NO];
    // Show your mail composer.
    [self presentViewController:mailComposer animated:YES completion:NULL];
 }
 else {
 // Here you can show toast to user about not support to sending email.
}
}

Step 4: Implement MFMailComposeViewController Delegate

- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(nullable NSError *)error {
[controller dismissViewControllerAnimated:TRUE completion:nil];


switch (result) {
   case MFMailComposeResultSaved: {
    // Add code on save mail to draft.
    break;
}
case MFMailComposeResultSent: {
    // Add code on sent a mail.
    break;
}
case MFMailComposeResultCancelled: {
    // Add code on cancel a mail.
    break;
}
case MFMailComposeResultFailed: {
    // Add code on failed to send a mail.
    break;
}
default:
    break;
}
}

MFMailComposeViewController is the way to go after the release of iPhone OS 3.0 software. You can look at the sample code or the tutorial I wrote.

Answer 5

A few things I'd like to add here:

1. Using the mailto URL won't work in the simulator as mail.app isn't installed on the simulator. It does work on device though.

2. There is a limit to the length of the mailto URL. If the URL is larger than 4096 characters, mail.app won't launch.

3. There is a new class in OS 3.0 that lets you send an e-mail without leaving your app. See the class MFMailComposeViewController.

Swift 2.0

func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?){
    if let error = error{
        print("Error: \(error)")
    }else{
        //NO Error
        //------------------------------------------------
        var feedbackMsg = ""

        switch result.rawValue {
        case MFMailComposeResultCancelled.rawValue:
            feedbackMsg = "Mail Cancelled"
        case MFMailComposeResultSaved.rawValue:
            feedbackMsg = "Mail Saved"
        case MFMailComposeResultSent.rawValue:
            feedbackMsg = "Mail Sent"
        case MFMailComposeResultFailed.rawValue:
            feedbackMsg = "Mail Failed"
        default:
            feedbackMsg = ""
        }

        print("Mail: \(feedbackMsg)")

        //------------------------------------------------
    }
}
