body: <p>I am working on an ios application in which i have to use custom fonts for UIs.
  I know how to integrate new custom fonts in application. For that i have</p>
  
  <ol>
  <li>Download font family files with .ttf extention.</li>
  <li>Add them to resource bundle.</li>
  <li>In info.plist file add with key Fonts provided by application.</li>
  </ol>
