如何從我的iOS應用程序發送郵件 - SWIFT

我想從我的應用程序發送郵件。我正在做SWIFT的第一步，並且我堅持了一個觀點。我想按下按鈕並打開郵件。你能告訴我如何做按鈕連接？我認爲它應該是一個動作，但我不知道在哪裏把它的代碼如何從我的iOS應用程序發送郵件 - SWIFT

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() 

    } 
}

變化sendEmail這樣的：

@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) 
}

，並連接在Interface Builder您的按鈕，這個動作

我一定要刪除FUNC sndEmail（）？ – jonathan

@jonathan只是改變FUNC sendEmail（）{線 – gvuksic

抱歉愚蠢的問題，但是當它就是這樣..它依然犯規工作 – jonathan

要發送郵件，一般使用MFMailComposer。它可以在設備上進行測試，因爲它不適用於iOS模擬器。

爲了測試郵件服務是否可用，使用下面的功能，

if !MFMailComposeViewController.canSendMail() { 
    print("Mail services are not available") 
    return 
}

，並在你的函數或按鈕的動作發送郵件，使用下面的代碼。

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)

有在發送郵件完成的委託方法，如下圖所示，其可以被定義，

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) 
}

感謝您的答案。並且如何啓用郵件服務？ –

安東普拉東諾夫補充：進口MessageUI在源文件的乞討，當你聲明類爲視圖控制器添加協議：類FirstVC：UIViewController中，MFMailComposeViewControllerDelegate {

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) 
}

委託方法

class SendMailViewController: MFMailComposeViewControllerDelegate { 
    func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) { 
     dismiss(animated: true, completion: nil) 
    } 
}

導入庫第一：

import MessageUI

組委託，如：

MFMailComposeViewControllerDelegate

寫漂亮的代碼：

@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 
}

還寫這樣的委託方法：

//MARK: - MFMail compose method 
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) { 
    controller.dismiss(animated: true, completion: nil) 
}

100％的工作和測試
