import UIKitimport MessageUIclass ViewController: UIViewController, MFMessageComposeViewControllerDelegate { @IBOutlet weak var phoneNumber: UITextField! override func viewDidLoad() { super.viewDidLoad() } @IBAction func sendText(sender: UIButton) { if (MFMessageComposeViewController.canSendText()) { let controller = MFMessageComposeViewController() controller.body = "Message Body" controller.recipients = [phoneNumber.text] controller.messageComposeDelegate = self self.presentViewController(controller, animated: true, completion: nil) } } func messageComposeViewController(controller: MFMessageComposeViewController!, didFinishWithResult result: MessageComposeResult) { //... handle sms screen actions self.dismissViewControllerAnimated(true, completion: nil) } override func viewWillDisappear(animated: Bool) { self.navigationController?.navigationBarHidden = false }}
