How to hide React Native NavigationBar

Question

I have NavigatorIOS under Navigator and would like to hide Navigator's NavigationBar to use NavigatorIOS's bar. Is there any way to do this?

This is screenshot that I've seen. I need backend of NavigatorIOS..

The structure that I want to build is the following:

├── NavigatorRoute1
│   ├── NavigatorIOSRoute1
│   ├── NavigatorIOSRoute2
│   └── NavigatorIOSRoute3
└── NavigatorRoute2

The code that I have is the below. (Basically obtained from UIExplore examples.

Navigator

render: function(){
return (
  <Navigator
    initialRoute={ROUTE_STACK[this.getInitialRouteIndex()]}
    initialRouteStack={ROUTE_STACK}
    style={styles.container}
    renderScene={this.renderScene}
    navigationBar={
      <Navigator.NavigationBar
        routeMapper={NavigationBarRouteMapper}
        style={styles.navBar}
      />
    }
  />
);
}

NavigatorIOS

render: function(){
var nav = this.props.navigator;
 return (
  <NavigatorIOS
    style={styles.container}
    ref="nav"
    initialRoute={{
      component: UserSetting,
      rightButtonTitle: 'Done',
      title: 'My View Title',
      passProps: {nav: nav},
    }}
    tintColor="#FFFFFF"
    barTintColor="#183E63"
    titleTextColor="#FFFFFF"
  />
);

}

UPDATE with my solution

I added a function to change state that handle rendering of Navigator and pass the prop to the component to change the state.

hideNavBar: function(){
  this.setState({hideNavBar: true});
},
render: function(){
 if ( this.state.hideNavBar === true ) {
  return (
    <Navigator
      initialRoute={ROUTE_STACK[0]}
      initialRouteStack={ROUTE_STACK}
      renderScene={this.renderScene}
    />
  );
 }else{
  return (
    <Navigator
      initialRoute={ROUTE_STACK[this.getInitialRouteIndex()]}
      initialRouteStack={ROUTE_STACK}
      style={styles.container}
      renderScene={this.renderScene}
      navigationBar={
        <Navigator.NavigationBar
          routeMapper={NavigationBarRouteMapper}
          style={styles.navBar}
        />
      }
    />
  );
}

}

and

render: function(){
 var hideNavBar = this.props.hideNavBar;
 return (
  <NavigatorIOS
    style={styles.container}
    initialRoute={{
      component: UserSetting,
      rightButtonTitle: 'Done',
      title: 'My View Title',
      passProps: {hideNavBar: hideNavBar},
    }}
    tintColor="#FFFFFF"
    barTintColor="#183E63"
    titleTextColor="#FFFFFF"
  />
 );

}

Answer 1

Because some old methods are deprecated i used stacknavigator. It works for me, if you are using StackNavigator.

//******For Older Versions. But Will be Deprecated in future*******
//static navigationOptions = { title: 'Welcome', header: null };

//For Latest Version Use:
static navigationOptions = { title: 'Welcome', headerShown: false};

Feel free to contact, if any issue.
