body: <p>How to add an image to an UIView? Here is what I tried so far:</p>
  
  <pre><code>UIView *imageHolder = [[UIView alloc] initWithFrame:CGRectMake(40, 200, 280, 192)];
  UIImage *image = [UIImage imageNamed:@"bloodymoon.jpg"];
  [imageHolder addSubview:image]; // Error: Incompatible pointer types
  [self.mainView addSubview:imageHolder];
  </code></pre>
