title: Getting the exact location of a UITableViewCell
body: <p>Given a <code>UITableView</code>, how can I find the location of a specific <code>UITableViewCell</code>? In other words, I want to get its frame relative to my iPhone screen, not relative to the <code>UITableView</code>. So if my <code>UITableView</code> is scrolled up, the location of each <code>UITableViewCell</code> should be higher on the screen, etc.</p>
