[NavigatorIOS] Why NavigatorIOS overlaps upper part of inner component?

I’ve just generated empty React-Native project (using react-native init) and added sample NavigatorIOS code.

/**
 * Sample React Native App
 * https://github.com/facebook/react-native
 */
'use strict';

var React = require('react-native');
var {
  AppRegistry,
  StyleSheet,
  Text,
  NavigatorIOS,
  View,
} = React;

var TestProject = React.createClass({
  render: function() {
    return (
      <View style={styles.container}>
        <Text style={styles.welcome}>
          Welcome to React Native!
        </Text>
        <Text style={styles.instructions}>
          To get started, edit index.ios.js
        </Text>
        <Text style={styles.instructions}>
          Press Cmd+R to reload,{'\n'}
          Cmd+D or shake for dev menu
        </Text>
      </View>
    );
  }
});

var Test = React.createClass( {
  render() {
    return (
      <NavigatorIOS
        style={{flex:1}}
        initialRoute={{
          title: 'Preference',
          component: TestProject
        }}
        />
    );
  }
});

var styles = StyleSheet.create({
  container: {
    flex: 1,
  },
  welcome: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  },
  instructions: {
    textAlign: 'center',
    color: '#333333',
    marginBottom: 5,
  },
});

AppRegistry.registerComponent('TestProject', () => Test);

FYI: For those coming across this issue, a more stable solution than setting paddingTop: 64 is turning off the translucent property.

<NavigatorIOS
   translucent={false}
   initialRoute={{
      ...
   }}/>

This is default iOS behavior since iOS 7 when they made the Navigation Bar translucent. Content is supposed to be able to visually scroll beneath the nav bar.

Anyway, if you don’t need that functionality, just set paddingTop: 64 on your container style which will start everything beneath the nav bar.
