Hello i want to open the eMail program from my App and the body should already be defined. I can open the eMail but don't know how to define the body of the eMail as a given Parameter to show a given standard text. Anyone can help? Heres the code i use to open Email:

//EMAIL

let email = "foo@bar.com"

let urlEMail = NSURL(string: "mailto:(email)")



if UIApplication.sharedApplication().canOpenURL(urlEMail!) {

                UIApplication.sharedApplication().openURL(urlEMail!)

} else {

print("Ups")

}

You can do it using MFMailComposeViewController:

import MessageUI



let mailComposerVC = MFMailComposeViewController()

mailComposerVC.mailComposeDelegate = self

mailComposerVC.setToRecipients(["email@email.com"])

mailComposerVC.setSubject("Subject")

mailComposerVC.setMessageBody("Body", isHTML: false)

self.presentViewController(mailComposerVC, animated: true, completion: nil)

Also, you need to implement mailComposeController:didFinishWithResult:error: from MFMailComposeViewControllerDelegate where you should dismiss MFMailComposeViewController

If you'd like to open the built-in email app as opposed to showing the MFMailComposeViewController as has been mentioned by others, you could construct a mailto: link like this:

let subject = "My subject"

let body = "The awesome body of my email."

let encodedParams = "subject=(subject)&body=(body)".stringByAddingPercentEncodingWithAllowedCharacters(.URLQueryAllowedCharacterSet())

let url = "mailto:foo@bar.com?(encodedParams)"



if let emailURL = NSURL(url) {

    if UIApplication.sharedApplication().canOpenURL(emailURL) {

        UIApplication.sharedApplication().openURL(emailURL)

    }

}

Just to save anyone typing, for 2016 the syntax has changed slightly:

let subject = "Some subject"

let body = "Plenty of email body."

let coded = "mailto:blah@blah.com?subject=(subject)&body=(body)".stringByAddingPercentEncodingWithAllowedCharacters(.URLQueryAllowedCharacterSet())



if let emailURL:NSURL = NSURL(string: coded!)

    {

    if UIApplication.sharedApplication().canOpenURL(emailURL)

        {

        UIApplication.sharedApplication().openURL(emailURL)

        }

Swift 3 Version

let subject = "Some subject"

let body = "Plenty of email body."

let coded = "mailto:blah@blah.com?subject=(subject)&body=(body)".addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)



if let emailURL: NSURL = NSURL(string: coded!) {

    if UIApplication.shared.canOpenURL(emailURL as URL) {

        UIApplication.shared.openURL(emailURL as URL)

    }

}

Swift 4.0

    let email = "feedback@company.com"

    let subject = "subject"

    let bodyText = "Please provide information that will help us to serve you better"

    if MFMailComposeViewController.canSendMail() {

        let mailComposerVC = MFMailComposeViewController()

        mailComposerVC.mailComposeDelegate = self

        mailComposerVC.setToRecipients([email])

        mailComposerVC.setSubject(subject)

        mailComposerVC.setMessageBody(bodyText, isHTML: true)

        self.present(mailComposerVC, animated: true, completion: nil)

    } else {

        let coded = "mailto:(email)?subject=(subject)&body=(bodyText)".addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)

        if let emailURL = URL(string: coded!)

        {

            if UIApplication.shared.canOpenURL(emailURL)

            {

                UIApplication.shared.open(emailURL, options: [:], completionHandler: { (result) in

                    if !result {

                        // show some Toast or error alert

                        //("Your device is not currently configured to send mail.")

                    }

                })

            }

        }

    }

Use the MFMailComposeViewController like this:

1. 
   

   Import the MessageUI

   
   
   

   import MessageUI
   
   

   
   


2. 
   

   Add the delegate to your class:

   
   
   

   class myClass: UIViewController, MFMailComposeViewControllerDelegate {}
   
   

   
   


3. 
   

   Configure the email preset you want to have

   
   
   

   let mail = MFMailComposeViewController()
   
   mail.mailComposeDelegate = self
   
   mail.setSubject("Subject")
   
   mail.setMessageBody("Body", isHTML: true)
   
   mail.setToRecipients(["my@email.com"])
   
   presentViewController(mail, animated: true, completion: nil)
   
   

   
   


4. 
   

   Put this method in your code:

   
   
   

   func mailComposeController(controller: MFMailComposeViewController!, didFinishWithResult result: MFMailComposeResult, error: NSError!) {
   
       dismissViewControllerAnimated(true, completion: nil)
   
   }
   
   

   
   

There you go, works now.

I suggest to use Apple's way, which you can find in official documentation about MFMailComposeViewController. It opens a modal view controller with the email, which is dismissed after sending. Thus user stays in your app.
