Custom navigation with Navigator component in React-Native

I’m exploring possibilities of React Native while developing a demo app with custom navigation between views with the help of Navigator component.

The main app class renders navigator and inside renderScene returns passed component:

class App extends React.Component {    render() {        return (<Navigator                initialRoute={{name: 'WelcomeView', component: WelcomeView}}                configureScene={() => {                    return Navigator.SceneConfigs.FloatFromRight;                }}                renderScene={(route, navigator) => {                    // count the number of func calls                    console.log(route, navigator);                     if (route.component) {                        return React.createElement(route.component, { navigator });                    }                }}             />        );    }}

For now app contains two views:

class FeedView extends React.Component {    render() {        return (<View style={styles.container}><Text>                    Feed View!</Text></View>        );    }}class WelcomeView extends React.Component {    onPressFeed() {        this.props.navigator.push({            name: 'FeedView',            component: FeedView        });    }    render() {        return (<View style={styles.container}><Text style={styles.welcome}>                    Welcome View!</Text><Text onPress={this.onPressFeed.bind(this)}>                    Go to feed!</Text></View>        );    }}

What I want to figure out is:

• I see in the logs that when pressing “go to feed”renderScene is called several times though the view renders correctly once. Is it how the animation works?

  index.ios.js:57 Object {name: 'WelcomeView', component: function}index.ios.js:57 Object {name: 'FeedView', component: function}// renders Feed View

• Generally does my approach conform to the React way, or can it be done better?

What I want to achieve is something similar to NavigatorIOS but without the navigation bar (however some views will have their own custom navigation bar).
