pressedCancelButton resigns always without respecting the delegate

[Blackjacx]

Current implementation:

func pressedCancelButton(_ sender: AnyObject) {
        textField.resignFirstResponder()
        _ = delegate?.searchBarShouldCancel?(self)
}

Better implementation:

func pressedCancelButton(_ sender: AnyObject) {
	if delegate?.searchBarShouldCancel?(self) ?? true {
		textField.resignFirstResponder()
	}
}
