title: Objective-C : UIScrollView manual paging
body: <p>I want to use the scrollview as something like a picker in horizontal mode.
  The scrollview holds up to seven subviews.
  Each subview represents a value.
  Always three views are visible and the one in the middle is the selected one.</p>
  
  <p>Scrollview visible at start:  </p>
  
  <p>__ | V1 | V2 </p>
  
  <p>Scrollview set to view/value two:</p>
  
  <p>V1 | V2 | V3</p>
  
  <p>Scrollview set to last value:</p>
  
  <p>V2 | V3 | __</p>
  
  <p>The real problem I have got is the "pagingEnabled" flag.
  If pagingEnabled is set to YES the scrollview pages always three subviews/values instead of only one.
  If pagingEnabled is set to NO the scrollview does not clinch.</p>
  
  <p>Is there a nice solution for my problem?</p>
  
  <p>Thanks a lot,
  Dan ;)</p>
