Swift – Open an Alert box

Opening an alert in iOS is very easy. Use the UIAlertController. This creates a special ViewController that can be displayed in one of two styles Alert, or ActionSheet.

 

let alert = UIAlertController(title: "Send Cypher", message: nil, preferredStyle: UIAlertControllerStyle.ActionSheet)
let message = UIAlertAction(title: "Message", style: UIAlertActionStyle.Default) { (action: UIAlertAction) -> Void in
    // Do something when message is tapped
}

let email = UIAlertAction(title: "Email", style: UIAlertActionStyle.Default) { (action: UIAlertAction) -> Void in
    // Do something when email is tapped
}

let cancel = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel, handler: nil)
alert.addAction(message)
alert.addAction(email)
alert.addAction(cancel)

presentViewController(alert, animated: true, completion: nil)

Swift – Send Email

Sending email with Swift is easy with MFMailComposeViewController. Follow these steps: 

Step 1: Import the MessageUI framework

import MessageUI

Step 2: Add the Protocol to your ViewController

MFMailComposeViewControllerDelegate

Step 3: Add the delegate method

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

 

Step 4: Make an instance of the MailComposeViewController, and present it.

func sendEmail() {
    let mailVC = MFMailComposeViewController()
    mailVC.mailComposeDelegate = self
    mailVC.setToRecipients([])
    mailVC.setSubject("Message Subject")
    mailVC.setMessageBody("Message text...", isHTML: true)
    
    presentViewController(mailVC, animated: true, completion: nil)
}

Swift – Send SMS Messages

Sending SMS messages in Swift is very easy. You can add the capability to any app with a few lines of code.

Note: This will not work in the simulator, as the simulator doesn’t support SMS messages!

Step 1: Import MessageIU

Add the following to the top of your ViewController.

import MessageUI

Step 2: Add the Protocol

Add the MFMessageComposeViewControllerDelegate your ViewController definition. 

Step 3: Conform to the protocol

Conform to the MFMessageComposeControllerDelegate by adding defining the:

messageComposeViewController:didFinishWithResult method. It might look something like:

func messageComposeViewController(controller: MFMessageComposeViewController, didFinishWithResult result: MessageComposeResult) {
    switch result.rawValue {
    case MessageComposeResultCancelled.rawValue :
        print("message canceled")
        
    case MessageComposeResultFailed.rawValue :
        print("message failed")
        
    case MessageComposeResultSent.rawValue :
        print("message sent")
        
    default:
        break
    }
    controller.dismissViewControllerAnimated(true, completion: nil)
}
}

You can omit the switch statement. The switch statement provides some feedback to you on the status of the message. Use this to notify your user when a message fails, or is canceled. Or omit if this is unimportant.

Step 3: Open the Message View controller

func sendMessage() {
    let messageVC = MFMessageComposeViewController()
    messageVC.body = "Message string"
    messageVC.recipients = [] // Optionally add some tel numbers
    messageVC.messageComposeDelegate = self
    // Open the SMS View controller
    presentViewController(messageVC, animated: true, completion: nil)
}
