title: Overlay an UIImage above an UIImageView, possible? example code?
body: <p>Is it possible to set an image over an other image, 
  respectively to overlay an image above an UIImage. </p>
  
  <p>I give some code:</p>
  
  <ul>
  <li><p>Headerfile:</p>
  
  <pre><code>@property (nonatomic,assign)UIImageView* imageView;
  </code></pre></li>
  <li><p>Implementationfile</p>
  
  <pre><code>UIImage *overlayImage = [UIImage imageNamed:@"lamp.png"];
  </code></pre></li>
  </ul>
  
  <hr>
  
  <p>The "imageView.image" has got an image and above that I will have this lamp, but later on it has to be possible to move it. </p>
  
  <p>I searched some methods, but all methods gave me warnings. </p>
  
  <p>Could you help me how to manage it? And is Core Animation an alternative to handle that?</p>
