title: UIScrollView does not scroll offset when voice over is on iOS7
body: <p>We have a custom pull to refresh view that is used on on class extending UIScrollViews, everything works fine, however iOS7 disabled the bounce in the ScrollView when VoiceOver is enabled, which renders the pullToRefresh useless.</p>
  
  <p>I am wondering if anyone has been able to see this, and if anyone could give some hints on how to solve this, setting the bounce property to YES when voiceOver is running does not solve it at all.</p>
  
  <p>Update: Tested this issue with existing apps in iOS7 (facebook and gmail), and they all suffer the same issue.</p>
  
  <p>Thanks.</p>
