Open eMail from App with predefined text in iOS

Question

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")
}

Do some research on the `mailto:` URL scheme. You can provide "to" addresses, "cc" addresses, a subject, and the message body. But of course the best option is to do what the answers below suggest. — rmaddy, Nov 13 '15 at 14:53

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)
        }

the actual correct answer to the question on the page! thanks man! :) — Fattie, Jul 27 '16 at 18:36

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)
    }
}

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

Before you create your mailComposerVC it is not a bad idea to check if you actually can send an email using `MFMailComposeViewController.canSendMail()` – Au Ris May 02 '17 at 13:18

    if MFMailComposeViewController.canSendMail() {

Use the MFMailComposeViewController like this:

Import the MessageUI
```
import MessageUI
```

Add the delegate to your class:

class myClass: UIViewController, MFMailComposeViewControllerDelegate {}

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)

Put this method in your code:

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

There you go, works now.

Updated for Xcode 12.5

let url = NSURL(string: "mailto:mailto:someone@example.com")
                                            UIApplication.shared.open(url! as URL)

or if you would like to add an embedded subject

let url = NSURL(string: "mailto:someone@example.com?subject=This%20is%20the%20subject&cc=someone_else@example.com&body=This%20is%20the%20body")

or if you want to add multiple email addresses

let url = NSURL(string: "mailto:mailto:someone@example.com,someoneelse@example.com")
                                                UIApplication.shared.open(url! as URL)

Similar to url construction in the other answers, but instead of calling addingPercentEncoding you can use URLComponents:

var components = URLComponents(string: "youremail@test.com")
components?.queryItems = [URLQueryItem(name: "subject", value: "Your Subject")]

if let mailUrl = components?.url {
    UIApplication.shared.open(mailUrl, options: [:], completionHandler: nil)
}

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.

OP asked for Swift code, your reference displays Obj-C instead. – LinusGeffarth Nov 13 '15 at 14:57

The link leads to Apple's documentation, where are all information, which could Jan possibly need, not only specific parts (methods/properties). Apple has the sample code only in ObjC in this case, but it could be easily translated to Swift. – David Rysanek Nov 14 '15 at 10:14
