title: Move different UIView In UIScrollView
body: <p>In my iOS application i have a scrollview in which there are many imageviews and textviews.
  I have to move all this views down to a fixed value, but i don't want to move them to left, right or resize them. I just want to move them down, on an event. The problem is that i can't know which are the values of these UIView.</p>
  
  <p>This is my code:</p>
  
  <pre><code>for(UIView* subview in [myScrollView subviews])
  {
      subview.frame = CGRectMake(0, 0, screenWidth, screenHeight);
  } 
  </code></pre>
  
  <p>i'd like to do this:</p>
  
  <pre><code>for(UIView* subview in [myScrollView subviews])
  {
      subview.frame = CGRectMake(previousValue+100, previousValue, previousValue, previousValue);
  } 
  </code></pre>
  
  <p>I hope I explained myself</p>
