How to share content and posts on social apps like Facebook, Twitter, Email & Google+.

Now these days its very common and popular to share content or post on social app like Facebook, Twitter, Email & Google+. I have some stuff that I have used to share content and posts on social apps. Add the following code in the ViewController.swift file in order to be able to post on Facebook, Twitter, Email & Google+ by tapping the relative buttons.

MFMailComposeViewController

In this writing, I want explore how to use MFMailComposeViewController with Swift to send e-mails within your app as a walkthrough. My focus here is “quick and dirty” pragmatism, so that we can easily see what the inter-working components of MFMailComposeViewController are. That being said, here’s an important disclaimer – I’m going to overload the View Controller’s responsibilities in the examples to follow.

Email

import Social
import MessageUI

class ViewController: UIViewController, MFMailComposeViewControllerDelegate {

    @IBAction func tapEmail_btn(_ sender: Any) {
        
        let emailTitle = "Subject of mail"
        let messageBody = "Content of mail"
        let toRecipents = ["friend@example.com"]
        let mc: MFMailComposeViewController = MFMailComposeViewController()
        mc.mailComposeDelegate = self
        mc.setSubject(emailTitle)
        mc.setMessageBody(messageBody, isHTML: false)
        mc.setToRecipients(toRecipents)
        self.present(mc, animated: true, completion: nil)
        
    }
    
    func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
        switch result {
        case .cancelled:
            print("Mail cancelled")
        case .saved:
            print("Mail saved")
        case .sent:
            print("Mail sent")
        case .failed:
            print("Mail sent failure: \(error?.localizedDescription)")
        default:
            break
        }
        self.dismiss(animated: true, completion: nil)
    }    
}

import Social

import MessageUI

class ViewController: UIViewController, MFMailComposeViewControllerDelegate {

@IBAction func tapEmail_btn(_ sender: Any) {

let emailTitle = "Subject of mail"

let messageBody = "Content of mail"

let toRecipents = ["[email protected]"]

let mc: MFMailComposeViewController = MFMailComposeViewController()

mc.mailComposeDelegate = self

mc.setSubject(emailTitle)

mc.setMessageBody(messageBody, isHTML: false)

mc.setToRecipients(toRecipents)

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

}

func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {

switch result {

case .cancelled:

print("Mail cancelled")

case .saved:

print("Mail saved")

case .sent:

print("Mail sent")

case .failed:

print("Mail sent failure: \(error?.localizedDescription)")

default:

break

}

self.dismiss(animated: true, completion: nil)

}

SLComposeViewController

SLComposeViewController is part of the Social framework, provided by Apple. It presents to the users a view that enables them to edit a post that’s going to be shared on social networks, such as Facebook, Twitter and Google+. In order to share content, you’ll provide theSLComposeViewController with information such as URL and initial text. so we’re sharing our code in this blog post.

Facebook

import Social
import SafariServices

class ViewController: UIViewController , SFSafariViewControllerDelegate{
    @IBAction func tapFacebook_btn(_ sender: Any) {
        if SLComposeViewController.isAvailable(forServiceType: SLServiceTypeFacebook) {
            guard let composer = SLComposeViewController(forServiceType: SLServiceTypeFacebook) else { return }
            composer.add(URL(string: "https://mobikul.com/blog"))
            composer.setInitialText("Content to share")
            present(composer, animated: true, completion: nil)
        }else {
            let postText ="Content to share"
            let postUrl ="https://mobikul.com/blog"
            let shareString = "https://facebook.com/intent/post?text=\(postText)&url=\(postUrl)"
            let escapedShareString = shareString.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed)!
            let url = URL(string: escapedShareString)
            UIApplication.shared.openURL(url!)
        }
    }
}
