UITextView inside a UITableViewCell, how to resign textview's firstResponder when tableView scrolls?

Question

I created a custom UITableViewCell, and a UITextView was put inside this prototype cell. When I click on this textView, keyboard can bounce automatically. However, if I want to hide the keyboard, I will have to click Return key. It isn't quite convenient.

Here's the question. How can I resign the textView's firstResponder for hiding the keyboard when I scroll the tableview.

cellForRowAtIndex method is below.

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    var cell = UITableViewCell()
    if(indexPath.section == 0){
        cell = self.tableView.dequeueReusableCellWithIdentifier("InputCell")!
        let textView = cell.viewWithTag(102) as! UITextView
        textView.editable = true
        textView.keyboardType = UIKeyboardType.Default
        textView.delegate = self
        textView.targetForAction(#selector(FeedBackViewController.getTextViewInsideCell(_:)), withSender: textView)
    }
    if(indexPath.section == 1){
        cell = self.tableView.dequeueReusableCellWithIdentifier("ConfirmButtonCell")!
        let label = cell.textLabel
        label?.text = "send"
        label?.textAlignment = NSTextAlignment.Center
        label?.textColor = UIColor.redColor()
    }
    return cell
}

Here are some methods I have implemented.

func textView(textView: UITextView, shouldChangeTextInRange range: NSRange, replacementText text: String) -> Bool{
    if(text == "\n"){
        textView.resignFirstResponder()
        return false
    }
    return true
}

And I have no idea how to implement this method.

func scrollViewWillBeginDragging(scrollView: UIScrollView) {

}

You can try implement this on viewDidLoad, it will auto dismiss keyboard when tableview start dragging:

tableView.keyboardDismissMode = .Interactive or .OnDrag
