使用MFMailComposeViewController附加图像从PhotoGallery到电子邮件

Question

我希望用户从照片库中选择其所需的图像，然后将这些图像包含在他们将要发送的电子邮件中。

我已经创建了一个按钮，该按钮使用户可以打开图库，然后在选择图像后将其显示在UIImageView中。但是，我认为我撰写的代码是不正确的。

UIimageViews名称是ImageView

按钮以打开画廊

@IBAction func openPhotoLibraryButton(sender: AnyObject) {
    if UIImagePickerController.isSourceTypeAvailable(.photoLibrary) {
        let imagePicker = UIImagePickerController()
        imagePicker.delegate = self
        imagePicker.sourceType = .photoLibrary;
        imagePicker.allowsEditing = true
        self.present(imagePicker, animated: true, completion: nil)
    }
}

电子邮件代码

@IBAction func sendEmail(_ sender: Any) {
    if MFMailComposeViewController.canSendMail() {
        let mail = MFMailComposeViewController()
        let emailFullName: String = fullName.text!
        let emailCell: String = cellNumber.text!
        let image1: UIImage = imageView.image!
        mail.mailComposeDelegate = self
        //Reciepient
        mail.setToRecipients(["[email protected]"])
        // Email body
        mail.setMessageBody("FullName: \(emailFullName) \n Cellphone No: \(emailCell)"   , isHTML: false)
        // Subject
        mail.setSubject("Application for RTO: ")
        
        // Email attachment
        mail.addAttachmentData(Data, mimeType: "image/jpg", fileName: "\(image1)")
        self.present(mail, animated: true, completion: nil)
        }
     else {
        print("Email cannot be sent")
        
    }
}
