title: iOS webview can not use history back
body: <p>Have anyone used HTML5 history API in mobile webview? I get trouble when using history.back and history.go(-1) on iOS webview, nothing happend when I click a button (everything work fine on Android webview).</p>
  
  <pre><code>$(function() {
    $('#back').click(function() {
      history.go(-1); // not working
      history.back(); // not working
    });
  })
  </code></pre>
  
  <p>Thanks</p>
