【中文标题】单击表格视图单元格时启动默认电子邮件应用程序 - IOS【英文标题】：Launch Default Email App when clicked on Table View Cell - IOS 【发布时间】：2018-07-16 00:18:42 【问题描述】：我有这个标签，点击该标签后，用户应该会转到他们的默认电子邮件应用程序并为他们撰写邮件。
有人可以告诉我如何实现这个吗？
Let's say when someone clicks on feedback, they should be redirected to their default email app
【问题讨论】：
如果你想实现邮件功能，那么试试 MFMailComposeViewController。哪个推送邮件控制器，您可以在其中发送邮件。 【参考方案1】：这是发送邮件的代码。请阅读cmets了解代码
func sendEmail()
// check if device can send mail
if MFMailComposeViewController.canSendMail()
// create MFMailComposeViewController object
let mail = MFMailComposeViewController()
// set delegate to know when email has been sent and perform further tasks
mail.mailComposeDelegate = self
// In setToRecipients you can pass array of email to whom you want to send email
mail.setToRecipients(["someemail.com"])
// In setMessageBody you can pass the email body text
mail.setMessageBody("<p>some email text</p>", ishtml: true)
// here you can present the controller
present(mail, animated: true)
else
// show failure alert
//Unable to send Email(email may not be configured in your device)
// or may be you are using simulator
现在您可以使用委托方法来关闭 MFMailComposeViewController
extension YourViewController : MFMessageComposeViewControllerDelegate
func messageComposeViewController(_ controller: MFMessageComposeViewController,
didFinishWith result: MessageComposeResult)
// use result for further task
// Dismiss the MFMailComposeViewController.
controller.dismiss(animated: true, completion: nil)

【参考方案2】：以下是在 swift 4 上呈现默认电子邮件应用程序的扩展。
import MessageUI
extension UIViewController : MFMailComposeViewControllerDelegate
func configuredMailComposeViewController(recipients : [String]?, subject :
String, body : String, isHtml : Bool = false,
images : [UIImage]?) -> MFMailComposeViewController
let mailComposerVC = MFMailComposeViewController()
mailComposerVC.mailComposeDelegate = self // IMPORTANT
mailComposerVC.setToRecipients(recipients)
mailComposerVC.setSubject(subject)
mailComposerVC.setMessageBody(body, isHTML: isHtml)
//If you want to send images on Mail
for img in images ?? []
if let jpegData = UIImageJPEGRepresentation(img, 1.0)
mailComposerVC.addAttachmentData(jpegData,
mimeType: "image/jpg",
fileName: "Image")
return mailComposerVC
func presentMailComposeViewController(mailComposeViewController :
MFMailComposeViewController)
if MFMailComposeViewController.canSendMail()
self.present(mailComposeViewController,
animated: true, completion: nil)
else
self.showErrorAlert()
public func mailComposeController(controller: MFMailComposeViewController,
didFinishWith result: MFMailComposeResult,
error: Swift.Error?)
switch (result)
case .cancelled:
self.dismiss(animated: true, completion: nil)
case .sent:
self.dismiss(animated: true, completion: nil)
case .failed:
self.dismiss(animated: true, completion:
self.showErrorAlert()
)
default:
break;
func showErrorAlert()
let sendMailErrorAlert = UIAlertController.init(title: "Failed",
message: "Unable to send email. Please check your email " +
"settings and try again.", preferredStyle: .alert)
sendMailErrorAlert.addAction(UIAlertAction.init(title: "OK",
style: .default, handler: nil))
self.present(sendMailErrorAlert,
animated: true, completion: nil)
现在你可以像这样调用这些方法了。
@IBAction func didTapOpenEmailApp(sender: Any)
let toRecipients = ["desigredMail@example.com"]
let subject = "Your subject here"
let body = "Enter comments here..."
let mail = configuredMailComposeViewController(recipients: toRecipients, subject: subject, body: body, isHtml: false, images: nil)
presentMailComposeViewController(mailComposeViewController: mail)
编码愉快！

【参考方案3】：// email
let address = "test@test.com"
let url = URL(string: "mailto://\(address)")
UIApplication.shared.openURL(url!)
