title: React native Linking to another app
body: <p>I am trying to link to another app from my react native application (google maps for example).</p>
  
  <p>I required the Linking module as it's written here: <a href="https://facebook.github.io/react-native/docs/linking.html" rel="noreferrer">https://facebook.github.io/react-native/docs/linking.html</a></p>
  
  <p>My code contains a simple button which should open the navigation app and pass some location as properties:</p>
  
  <pre><code>&lt;TouchableOpacity 
     onPress={ () =&gt;{
       Linking.openURL("http://maps.google.com/maps=daddr=Wien")
       .catch(err =&gt; console.error('An error occurred', err)); }}
  &gt;
     &lt;Text&gt;Navigate&lt;/Text&gt;
  &lt;/TouchableOpacity&gt;
  </code></pre>
  
  <p>Upon loading the view I get no errors which implicates that requiring the module worked fine.</p>
  
  <p>Upon taping the button I get the following error message :</p>
  
  <pre><code>undefined is not an object (evaluating '_reactNative.Linking.openURL')
  </code></pre>

  <p>I have followed these steps : <a href="https://facebook.github.io/react-native/docs/linking-libraries-ios.html" rel="noreferrer">https://facebook.github.io/react-native/docs/linking-libraries-ios.html</a> and installed <code>npm install link --save</code> &lt;- Maybe the issue is that this is the wrong module?? If it is the wrong one does anyone know how the correct one is called?</p>
