title: React Native - How to use excludedActivityTypes property in ActionSheetIOS options parameter?
body: <p>I am new to <code>react native</code> and i don't have any background in <code>Objective-C</code> or <code>Swift</code>. The <a href="https://facebook.github.io/react-native/docs/actionsheetios#showshareactionsheetwithoptions" rel="nofollow noreferrer">documentation</a> does not provide enough content to understand the use of <code>excludedActivityTypes</code> property. Documentation says:</p>
  
  <blockquote>
    <p><strong>excludedActivityTypes</strong> (array) - the activities to exclude from the
    ActionSheet</p>
  </blockquote>
  
  <p>It takes array but i don't know what to mention in the array and what is the purpose of using this property. Can anyone tell its purpose and how to use it? A little example will be more appreciated. Thanks !!!</p>
