title: Trying to give UILabel a shadow, but it won't show up
body: <p>I'm trying to give a label in one of the classes in my app a drop shadow, but it's not working at all. Nothing shows up. What am I doing wrong?</p>
  
  <pre><code>// Set label properties
  titleLabel.font = [UIFont boldSystemFontOfSize:TITLE_FONT_SIZE];
  titleLabel.adjustsFontSizeToFitWidth = NO;
  titleLabel.opaque = YES;
  titleLabel.backgroundColor = [UIColor clearColor];
  titleLabel.textColor = titleLabelColor;
  titleLabel.shadowColor = [UIColor blackColor];
  titleLabel.shadowOffset = CGSizeMake(10, 10);
  </code></pre>
  
  <p>It's just white, no shadow.</p>
