ios - How to add a image in email body using MFMailComposeViewController

I am trying to find out the best way to add an image inside the body of the email and not as attachment in ios.

1) Apple has provided a function "addAttachment" and the doc says, to add any image in the content, we should use this function, but I tried that function, and sent an mail, I checked on my browser, it is recieved as an attachment.

2) Secondly, many blogs say to use base64 encoding, but that also wont work, image is sent as a broken one.

So friends, please help me out to find the best available solution to do this.

Regards Ranjit

Set email format as HTML. This code is woking fine in my app.

MFMailComposeViewController *emailDialog = [[MFMailComposeViewController alloc] init];

NSString *htmlMsg = @"<html><body><p>This is your message</p></body></html>";

NSData *jpegData = UIImageJPEGRepresentation(emailImage, 1.0);

NSString *fileName = @"test";
fileName = [fileName stringByAppendingPathExtension:@"jpeg"];
[emailDialog addAttachmentData:jpegData mimeType:@"image/jpeg" fileName:fileName];

emailDialog setSubject:@"email subject"];
[emailDialog setMessageBody:htmlMsg isHTML:YES];


[self presentModalViewController:emailDialog animated:YES];
[emailDialog release];

Swift 5

import MessageUI

    func composeMail() {

        let mailComposeVC = MFMailComposeViewController()

        mailComposeVC.addAttachmentData(UIImage(named: "emailImage")!.jpegData(compressionQuality: CGFloat(1.0))!, mimeType: "image/jpeg", fileName:  "test.jpeg")

        mailComposeVC.setSubject("Email Subject")

        mailComposeVC.setMessageBody("<html><body><p>This is your message</p></body></html>", isHTML: true)

        self.present(mailComposeVC, animated: true, completion: nil)
    }
