title: how to change the style of the font programmatically in objective-c
body: <p>I would like to change the style of the font (like bold, regular, light, oblique) programmatically. I know I can use the IB, but I would like to change it using programmatically. Need some guidance on this. Sorry if it is a stupid question.</p>
  
  <p>For example, my code looks like this:</p>
  
  <pre><code>lblAge.font = [UIFont fontWithName:@"Helvetica" size:20];
  </code></pre>
  
  <p>I would like to add the style which is regular in. How do I it?</p>
