title: UIScrollview delaysContentTouches issue
body: <p>I have <code>UIScrollView</code> loaded with <code>UIButtons</code> and on <code>UIButton</code> action I have highlighted <code>UIImage</code> of each <code>UIButton</code>.</p>
  
  <p>If I don't set <code>delaysContentTouches</code> as <code>NO</code> then highlighted <code>UIImage</code> of <code>UIButton</code> will not shown if I touch up <code>UIButton</code> very fast. After I set <code>delaysContentTouches</code> property as <code>NO</code> then only <code>UIButton</code> highlighted <code>UIImage</code> is shown.</p>
  
  <p>Now after setting <code>delaysContentTouches</code> property as NO for <code>UIScrollView</code>. I can not scroll my <code>UIScrollView</code> by dragging on the <code>UIButtons</code>. Now how can I resolve this issue. </p>
  
  <p>Please give me an advise.</p>
  
  <p>Thanks in advance.</p>
