How to dismiss keyboard for UITextView

Question

The following triggers when the Done button is clicked on the keyboard. It goes into the conditional and returns false. However, the keyboard remains on the screen.

class MyViewController: UIViewController, UITextViewDelegate{


func textView(textView: UITextView!, shouldChangeTextInRange: NSRange, replacementText: NSString!) -> Bool {
    if(replacementText.isEqualToString("\n")) {
        textBox.resignFirstResponder()
        return false
    }
    return true
}

textBox is a delegate for the view. I have connected this through Interface Builder. Any ideas why it isn't dismissing the keyboard?

At the bottom of the OP, I mention it is connected through IB. I even added textBox.delegate = self in viewDidLoad() but still nothing. — 4thSpace, Mar 18 '15 at 15:49
@4thSpace try to change textBox to `textView.resignFirstResponder()`, see if it works — IxPaka, Mar 18 '15 at 15:51
Use the textView that is passed in the delegate method instead of your property textBox. — Arbitur, Mar 18 '15 at 15:51
Ah I missunderstood you. Do you have any other delegate methods like `textViewShouldEndEditing` in use which could stop the resignfirstresponder to work? Also have you tried using textView, the parameter of the delegate instead of your textBox? — Christian, Mar 18 '15 at 15:52
Perfect! It should have been the passed in textView. Can one of you post as answer? — 4thSpace, Mar 18 '15 at 15:57

First of all please ensure that your My ViewController is a delegate of the textField, And then, on the method shouldChangeTextInRange use the textView that is passed in the delegate method instead of your property textBox.

For example:

class MyViewController: UIViewController, UITextViewDelegate{

    func viewDidLoad(){
      super.viewDidLoad()
      textBox.delegate = self
    }

func textView(textView: UITextView!, shouldChangeTextInRange: NSRange, replacementText: NSString!) -> Bool {
    if(replacementText.isEqualToString("\n")) {
        textView.resignFirstResponder()
        return false
    }
    return true
}
