title: How to adjust an UIButton's imageSize?
body: <p>How can I adjust the image size of the UIButton? I am setting the image like this:</p>
  <pre><code>[myLikesButton setImage:[UIImage imageNamed:@&quot;icon-heart.png&quot;] forState:UIControlStateNormal];
  </code></pre>
  <p>However this fills up the image to the full button, how do I make the image smaller?</p>

  <p>For this now 10+ yr old question, you now typically just set the point size using <code>setPreferredSymbolConfiguration</code></p>
