use of undeclared type 'MFMessageComposeViewControllerDelegate swift'

Question

i am trying to implement sending a text message using the MFMessageComposeViewController object. But when i am trying to declare the MFMessageComposeViewControllerDelegate protocol. In ViewController.swift i get the following error : use of undeclared type 'MFMessageComposeViewControllerDelegate swift'

ViewController.swift:

class ViewController: UIViewController, MFMessageComposeViewControllerDelegate {

@IBAction func sendMessage(sender: AnyObject) {
    var messageVC = MFMessageComposeViewController()

    messageVC.body = "Enter a message";
    messageVC.recipients = ["Enter tel-nr"]
    messageVC.messageComposeDelegate = self;

    self.presentViewController(messageVC, animated: false, completion: nil)
}


override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}
}

Can someone please help me?

Answer 1

Add the MessageUI Framework,

import UIKit
import MessageUI

class ViewController: UIViewController, MFMessageComposeViewControllerDelegate {

}

hope its helpful

Answer 2

All you need is to add

import MessageUI

at the top of your swift file. Also, you better to add check

if MFMessageComposeViewController.canSendText()

before send message, and don't forget to dismiss your message controller in delegate method

func messageComposeViewController(controller: MFMessageComposeViewController, didFinishWithResult result: MessageComposeResult) {
    dismissViewControllerAnimated(true, completion: nil)
}

You also need delegate to implement

func messageComposeViewController(controller: MFMessageComposeViewController, didFinishWithResult result: MessageComposeResult) {
        switch result.rawValue {
        case MessageComposeResultCancelled.rawValue:
            print("message cancelled")

        case MessageComposeResultFailed.rawValue:
            print("message failed")

        case MessageComposeResultSent.rawValue:
            print("message sent")

        default:
            break
        }

        controller.dismissViewControllerAnimated(true, completion: nil)
    }
