UIBarButtonItem when is pressed do nothing

I need that when the Done button on my toolbar, that is an accessory view of a textfield, make the keyboard to be dismissed. 

  func textFieldShouldBeginEditing(textField: UITextField) -> Bool {
    var toolBar = UIToolbar()
    var buttonOnToolbar = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Done, target: self, action: "dismiss")
    let arrayOfButtons = [buttonOnToolbar]
    toolBar.items = arrayOfButtons
    toolBar.barTintColor = UIColor.whiteColor()
    textField.inputAccessoryView = toolBar
    return true
}

func dismiss(sender: UIBarButtonItem) {
    println("cacca")
}

The function dismiss in just a tryout to see if something happens when the button is clicked. But when I press it nothing happens. Moreover the toolbar, although I changed his color remains transparent. What is wrong?

EDIT: Solved, the UIToolbar didn't have a size.

The problem is the wrong selector:

dismiss

selects a method that takes no argument. But your method takes one argument:

func dismiss(sender: UIBarButtonItem)

So your selector must be like this:

dismiss:

E.g.

UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Done, target: self, action: "dismiss:")
