Compose mail in the iPhone app

Question

In my app, I have an abouts page. I would like to place a round rect button which when I press it, I would be able to send an email to the company with an embedded email address.

Are there any tutorials to do this?

Thanks in advance.

Answer 1

Here's the code:

Obj-C:

(Don't forget to add the messageUI framework to your project!!!)

First import the message library:

#import <MessageUI/MessageUI.h>

Then mark your self as a delegate like this:

@interface MYViewController () <MFMailComposeViewControllerDelegate>

Then to pull up the composer (if user has email set up on their device):

- (IBAction)emailButtonPressed:(id)sender {
    if ([MFMailComposeViewController canSendMail]) {
        MFMailComposeViewController *composeViewController = [[MFMailComposeViewController alloc] initWithNibName:nil bundle:nil];
        [composeViewController setMailComposeDelegate:self];
        [composeViewController setToRecipients:@[@"[email protected]"]];
        [composeViewController setSubject:@"example subject"];
        [self presentViewController:composeViewController animated:YES completion:nil];
    }
}

Then to handle the delegate callback and dismiss the composer:

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
    //Add an alert in case of failure
    [self dismissViewControllerAnimated:YES completion:nil];
}

SWIFT 3:

Import the relevant library:

import MessageUI

Mark your view controller as a delegate like so:

class MyViewController: UIViewController, MFMailComposeViewControllerDelegate {

Pull up composer (if user has email set up on their device):

@IBAction func emailButtonAction(_ sender: UIButton) {
        
        if MFMailComposeViewController.canSendMail() {
            let mail = MFMailComposeViewController()
            mail.mailComposeDelegate = self
            mail.setToRecipients(["[email protected]"])
            mail.setSubject("Example Subject")
            mail.setMessageBody("<p>Test</p>", isHTML: true)
            present(mail, animated: true)
        }
    }

Handle delegate callback and dismiss the composer:

func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
    controller.dismiss(animated: true)
}
