Swift 4 Update

        // Create the alert controller
        let alertController = UIAlertController(title: "Title", message: "Message", preferredStyle: .alert)

        // Create the actions
        let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default) {
            UIAlertAction in
            NSLog("OK Pressed")
        }
        let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.cancel) {
            UIAlertAction in
            NSLog("Cancel Pressed")
        }

        // Add the actions
        alertController.addAction(okAction)
        alertController.addAction(cancelAction)

        // Present the controller
        self.present(alertController, animated: true, completion: nil)
