title: UIResponder class and first responder roles
body: <p>I read in the <code>UIResponder</code> class reference:</p>
  <blockquote>
  <p>There are two general kinds of events: touch events and motion events.</p>
  <p>The primary event-handling methods for touches are touchesBegan:withEvent:, touchesMoved:withEvent:, touchesEnded:withEvent:, and touchesCancelled:withEvent: ...</p>
  </blockquote>
  <p>but another article, the Event Handling Guide for iOS says:</p>
  <blockquote>
  <p>The first responder is the first view in a window to receive the following type of events and messages: Motion events, Remote-control events, Action messages, Editing-menu messages</p>
  </blockquote>
  <p>So I was confused that the second note says the responder handles only four events -- touch events were not included -- whereas the first note says the responder handles touch event.</p>
  <p>Please let me know what I am misunderstanding.</p>
