title: How to use a .ttc custom font in iOS
body: <p>I read that iOS supports .ttc files (font collection) but i don't know how to specify the different font weights with only one file.</p>
  
  <p>I am used to doing it by file name like this</p>
  
  <pre><code>[UIFont fontWithName:@"ProximaNova-Bold" size:17.0f];
  </code></pre>
  
  <p>but with a .ttc file i have only one file.</p>
