title: How do I set a marker in MapView of React Native
body: <ul>
  <li>I want to set a marker on MapView in React Native, but I can't find any information through official documents of <a href="https://facebook.github.io/react-native/docs/mapview.html#content" rel="noreferrer">MapView</a>.</li>
  <li>If it is not allowed in that way, how can I use existed react module such as <a href="https://github.com/pieterv/react-googlemaps" rel="noreferrer">react-googlemaps</a> in React Native?</li>
  </ul>
