title: UIScrollView performance
body: <p>I have problems with the performance</p>
  
  <p>There is a ScrollView, which are added 200 Buttons:</p>
  
  <pre><code>IMSeatControl * control = [[IMSeatControl alloc] initWithFrame: controlRect withSeatObject: seatObject];
  [control addTarget: self action: @ selector (seatButtonPressed:) forControlEvents: UIControlEventTouchUpInside];
  [_seatsContentView addSubview: control];
  </code></pre>
  
  <p>The button consists of picture and label.</p>
  
  <p>Is there a good way to improve the performance?</p>
