title: How to detect tap on clear part of UITableView?
body: <p>I have view controller with UITableView. Height of table view is static and == height of screen. Number of rows in table can change and sometimes it might be a situation when number of rows is less than number of rows which can be visible, so appears some clear area on bottom of table. Can i detect tap on it without gesture recognizer? Are there some delegate methods of UITableView?</p>
