how to send a mail from my iOS application- SWIFT
提问by jonathan
I want to send a mail from my application. I am doing my first steps with SWIFT and i have stuck at a point. I want to press a button and open up the mail. Can you please tell me how to do the button connection? I think it should be an action but I don't know where to put it on the code
我想从我的应用程序发送邮件。我正在用 SWIFT 做我的第一步，但我一直坚持在某个点上。我想按下一个按钮并打开邮件。你能告诉我如何进行按钮连接吗？我认为它应该是一个动作，但我不知道将它放在代码的何处
import UIKit
import MessageUI
class ViewController: UIViewController, MFMailComposeViewControllerDelegate {
func sendEmail() {
let mailVC = MFMailComposeViewController()
mailVC.mailComposeDelegate = self
mailVC.setToRecipients([])
mailVC.setSubject("Subject for email")
mailVC.setMessageBody("Email message string", isHTML: false)
presentViewController(mailVC, animated: true, completion: nil)
}
// MARK: - Email Delegate
func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?) {
controller.dismissViewControllerAnimated(true, completion: nil)
}
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}

Import library first:
先导入库：
import MessageUI
set delegate like:
设置委托如下：
MFMailComposeViewControllerDelegate
Write pretty code:
写出漂亮的代码：
@IBAction func buttonHandlerSendEmail(_ sender: Any) {
let mailComposeViewController = configureMailComposer()
if MFMailComposeViewController.canSendMail(){
self.present(mailComposeViewController, animated: true, completion: nil)
}else{
print("Can't send email")
}
}
func configureMailComposer() -> MFMailComposeViewController{
let mailComposeVC = MFMailComposeViewController()
mailComposeVC.mailComposeDelegate = self
mailComposeVC.setToRecipients([self.textFieldTo.text!])
mailComposeVC.setSubject(self.textFieldSubject.text!)
mailComposeVC.setMessageBody(self.textViewBody.text!, isHTML: false)
return mailComposeVC
}
Also write delegate method like:
还要编写委托方法，如：
//MARK: - MFMail compose method
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
controller.dismiss(animated: true, completion: nil)
}
100% working and tested

change sendEmaillike this:
sendEmail像这样改变：
@IBAction func sendEmail(sender: AnyObject) {
let mailVC = MFMailComposeViewController()
mailVC.mailComposeDelegate = self
mailVC.setToRecipients([])
mailVC.setSubject("Subject for email")
mailVC.setMessageBody("Email message string", isHTML: false)
presentViewController(mailVC, animated: true, completion: nil)
}
and connect in Interface builder your button to this action
并在界面构建器中将您的按钮连接到此操作

Swift 3
斯威夫特 3
let composer = MFMailComposeViewController()
if MFMailComposeViewController.canSendMail() {
composer.mailComposeDelegate = self
composer.setToRecipients(["Email1", "Email2"])
composer.setSubject("Test Mail")
composer.setMessageBody("Text Body", isHTML: false)
present(composer, animated: true, completion: nil)
}
Delegate method
委托方法
class SendMailViewController: MFMailComposeViewControllerDelegate {
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
dismiss(animated: true, completion: nil)
}
}

To send mail, generally MFMailComposer is used. It can be tested on device as it doesn't work on iOS simulator.
发送邮件，一般使用MFMailComposer。它可以在设备上进行测试，因为它不适用于 iOS 模拟器。
For testing whether mail service is available or not, use below function,
要测试邮件服务是否可用，请使用以下功能，
if !MFMailComposeViewController.canSendMail() {
print("Mail services are not available")
return
}
and to send mail, use below code in your function or action of button.
并发送邮件，请在您的功能或按钮操作中使用以下代码。
let composeVC = MFMailComposeViewController()
composeVC.mailComposeDelegate = self
// Configure the fields of the interface.
composeVC.setToRecipients(["[email protected]"])
composeVC.setSubject("Hello World!")
composeVC.setMessageBody("Hello from iOS!", isHTML: false)
// Present the view controller modally.
self.presentViewController(composeVC, animated: true, completion: nil)
There is delegate method on completion of sending mail which can be defined as below shown,
有完成发送邮件的委托方法，可以定义如下所示，
func mailComposeController(controller: MFMailComposeViewController,
didFinishWithResult result: MFMailComposeResult, error: NSError?) {
// Check the result or perform other tasks.
// Dismiss the mail compose view controller.
controller.dismissViewControllerAnimated(true, completion: nil)
}

to Anton Platonov add: import MessageUI at the begging of your source file, and when you declaring class for your view controller add protocol: class FirstVC: UIViewController, MFMailComposeViewControllerDelegate{
向 Anton Platonov 添加：在源文件中导入 MessageUI，并在为视图控制器声明类时添加协议：class FirstVC: UIViewController, MFMailComposeViewControllerDelegate{
