If you feel like needing a bit more from the React Native <NavigatorIOS /> component, that lets you implement routing, then check react-native-router from Tristan Edwards and rejoice.

This marvelous component is the Swiss Army knife of App routing with a full set of configurations, such as:

• Styles for Header
• Styles for Title
• Custom Component for Back Button
• Custom Component for Title, such as a Search Bar
• Custom Component for the Right Button
• Header color transition between routes

This and many more options you can find in the twitter-example and on the GitHub repo, of course.
