Dismiss custom keyboard programmatically in iOS

I am new to this forum. I am having problem creating a custom keyboard programmatically for my app only (no third-party keyboard installation). I successfully created a custom inputView and inserted UIButton. I wrote dismissKeyboard function to dismiss the keyboard but it did not work. Does anyone know how to fix or have another way to do it? Any help will be appreciated.

import UIKit

class ViewController: UIInputViewController, UITextFieldDelegate {

    @IBOutlet weak var textfield: UITextField!

    var keyBoardView: UIInputView!
    var myFirstButton: UIButton!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        keyBoardView = UIInputView(frame: CGRectMake(0, 0, view.frame.size.width, 100), inputViewStyle: .Keyboard)

        myFirstButton = UIButton(frame: CGRectMake(100, 0, 100, 50))
        myFirstButton.setTitle("1", forState: .Normal)
        myFirstButton.addTarget(self, action: "dismissAction:", forControlEvents: .TouchUpInside)
        keyBoardView.addSubview(myFirstButton)

        self.textfield.delegate = self
        textfield.inputView = keyBoardView

    func dismissAction(sender: UIButton!) {
        self.dismissKeyboard()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func textFieldShouldReturn(_textField: UITextField!) -> Bool {
        var nextTag = _textField.tag + 1
        var nextResponder = _textField.superview?.viewWithTag(nextTag)
        if ((nextResponder) != nil) {
            nextResponder?.becomeFirstResponder()
        }
        else {_textField.resignFirstResponder()}
        return true;
    }
}
