dismiss keyboard with a uiTextView

Question

I am sure this is not that difficult, but I am having trouble finding info on how to dismiss a keyboard with the return/done key using a textview, not a textfield. here is what I have tried so far(which works with a textfield.)

Thanks very much in advance for any help!

//  PostTravelQuestion.swift  class PostTravelQuestion: UIViewController, UITextViewDelegate {      @IBAction func closepostpage(sender: AnyObject) {         dismissViewControllerAnimated(true, completion: nil)     }       @IBOutlet var postquestion: UITextView!       override func viewDidLoad() {         super.viewDidLoad()          // Do any additional setup after loading the view.         postquestion.delegate = self     }      self addDoneToolBarToKeyboard:self.textView       /*func textViewShouldEndEditing(textView: UITextView) -> Bool {          textView.resignFirstResponder()          return true     }*/      /*override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {         postquestion.resignFirstResponder()         self.view.endEditing(true)     }*/        override func didReceiveMemoryWarning() {         super.didReceiveMemoryWarning()         // Dispose of any resources that can be recreated.     }       func textViewShouldReturn(textView: UITextView!) -> Bool {         self.view.endEditing(true);         return true;     } }

This works for me:

import UIKit  class ViewController: UIViewController, UITextViewDelegate {       @IBOutlet weak var textView: UITextView!      override func viewDidLoad() {         super.viewDidLoad()          textView.delegate = self     }      /* Updated for Swift 4 */     func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool {         if(text == "\n") {             textView.resignFirstResponder()             return false         }         return true     }      /* Older versions of Swift */     func textView(textView: UITextView, shouldChangeTextInRange range: NSRange, replacementText text: String) -> Bool {         if(text == "\n") {             textView.resignFirstResponder()             return false         }         return true     }  }
