Answer 1

I just went through this recently for Swift.

Function to add photo to email in Swift:

func postEmail() {
    var mail:MFMailComposeViewController = MFMailComposeViewController()
    mail.mailComposeDelegate = self
    mail.setSubject("your subject here")

    var image = // your image here
    var imageString = returnEmailStringBase64EncodedImage(image)
    var emailBody = ""

    mail.setMessageBody(emailBody, isHTML:true)

    self.presentViewController(mail, animated: true, completion:nil)
}

Function to return the formatted image:

func returnEmailStringBase64EncodedImage(image:UIImage) -> String {
    let imgData:NSData = UIImagePNGRepresentation(image)!;
    let dataString = imgData.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(rawValue: 0))
    return dataString
}
