如何在HTML Body Email Swift 3中插入图像？
我在我的应用程序中努力工作，但我遇到了问题。 需要在我的HTML代码中插入来自Swift的图像以发送电子邮件。
这是我的代码，但当然不起作用！
var h = "" h = h + "
" h = h + "" 请尝试下面的代码，在Email HTML Body中插入图片。
代码适用于Swift 4.0和Swift 3.1
import MessageUI class ViewController: UIViewController, MFMailComposeViewControllerDelegate{ override func viewDidLoad() { super.viewDidLoad() } //MARK: - Send Email @IBAction func actionSendEmail(_ sender: Any) { if !MFMailComposeViewController.canSendMail() { print("Mail services are not available") return } let image = UIImage(named:"testImage") // Your Image let imageData = UIImagePNGRepresentation(image!) ?? nil let base64String = imageData?.base64EncodedString() ?? "" // Your String Image let strHtml = "Header: Hello Test Email
 ))
" let composeVC = MFMailComposeViewController() composeVC.mailComposeDelegate = self // Configure the fields of the interface. composeVC.setToRecipients(["address@example.com"]) composeVC.setSubject("Hello!") composeVC.setMessageBody(strHtml, isHTML: true) // Present the view controller modally. self.present(composeVC, animated: true, completion: nil) } //MARK:- MFMailCompose Delegate Methods func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) { // Dismiss the mail compose view controller. controller.dismiss(animated: true, completion: nil) } }
给出完整的图像路径：喜欢
