title: iOS equivalent to a stylesheet?
body: <ul>
  <li><strong>HTML</strong> has CSS styles e.g. class="styleName"</li>
  <li><strong>Windows8/XAML</strong> has static style resources e.g. Style="{StaticResource styleName}"</li>
  <li><strong>Android</strong> has style tags e.g. style="@style/styleName"</li>
  <li><strong>iOS</strong> has <strong>???</strong></li>
  </ul>
  
  <p>I'm using the interface builder for iOS in Xcode, how do I start to build up a style set or equivalent to styles? I want the ability to apply '<strong>styles</strong>' to elements and then if I update that style's properties, the changes are applied to all elements that have been given that style. Is this possible in iOS development? <strong>Can someone please enlighten me as to how this is achieved or the equivalent please in iOS development</strong>. I'm very new to iOS development as you can see.</p>
  
  <p>Is it more related to skins or themes? I don't have a clue.</p>
