title: iphone refresh images UIImageView
body: <p>I have a rather basic question.   I have several(5) <code>UIImageView</code> images on
  my screen.  When I click a button,   I want to change each image
  to something else.  I also want to play a sound as each image is changed.</p>
  
  <p>So I basically want a clicking sound as each image changes.</p>
  
  <p>The problem is,  for some reason if I have say 5 images,<br>
  the sound gets played 5 times first and then the images change.</p>
  
  <p>It's like the images only refresh when control goes back to the 
  user for input.</p>
  
  <p>How can I "force" it to  refresh the images as soon as i tell it what image to display?</p>
  
  <p>I'm new to the iphone/macworld,  so go easy on me :-)</p>
