title: How can I save a string array to PlayerPrefs in Unity?
body: <p>I have an array and I would like to save it to PlayerPrefs. I heard, I can do this:</p>
  <pre><code>PlayerPrefs.SetStringArray('title', anArray);
  </code></pre>
  <p>but for some reason it does not work.
  Maybe I'm not using some library like <code>using UnityEngine.PlayerPrefs;</code>?</p>
  <p>Can someone help me?</p>
  <p>Thanks in advance</p>
