title: Need help in adding a drop shadow to an image in a uiview in iOS4?
body: <p>I am trying to create a drop shadow for an image.  I also have an animation between views and this is the backdrop.  However, when I use the following code, the image is not drawn.  Anyone have any ideas?</p>
  
  <pre><code>self.frontViewBackground = [[[UIView alloc] initWithFrame:frame] autorelease];
  //self.frontViewBackground.image = [UIImage imageNamed:@"whitepaper3.png"];
  self.frontViewBackground.multipleTouchEnabled = YES;
  [self.photoView addSubview:self.frontViewBackground];
  
  UIImage *image = [UIImage imageNamed:@"whitepaper3.png"]; 
  
  CGContextRef ctx = UIGraphicsGetCurrentContext();
  
  CGContextSetShadow(ctx, CGSizeMake(1, -2), 3.0);
  [image drawInRect:self.frontViewBackground.frame blendMode:kCGBlendModeNormal alpha:1.0];
  CGContextRestoreGState(ctx);
  </code></pre>
