title: How to use a custom font with dynamic text sizes in iOS7
body: <p>In iOS7 there are new API's for getting a font that is automatically adjusted to the text size the user has set in their preferences.</p>
  <p>It looks something like this to use it:</p>
  <pre><code>UIFont *myFont = [UIFont fontWithDescriptor:[UIFontDescriptor preferredFontDescriptorWithTextStyle:UIFontTextStyleHeadline] size:0];
  </code></pre>
  <p>Now whatever text you assign this to will move up and down in font size as the user changes their system text size setting. (Remember to listen to the <code>name:UIContentSizeCategoryDidChangeNotification</code> notification and update your view to account for the change in size).</p>
