title: Concatenate int and string
body: <p>How can I concatenate an <code>int</code> (e.g: <code>4</code>) and a string (e.g: <code>@"/12"</code>) for printing?</p>
  
  <p>I'm okay with casting the <code>int</code> it to an <code>NSString</code> format, but I don't know how I can add <code>@"/12"</code> after the int's value.</p>
