NavigatorIOS is a wrapper around UINavigationController, enabling you to implement a navigation stack. It works exactly the same as it would on a native app using UINavigationController, providing the same animations and behavior from UIKit.

As the name implies, it is only available on iOS. Take a look at React Navigation for a cross-platform solution in JavaScript, or check out either of these components for native solutions: native-navigation, react-native-navigation.

To set up the navigator, provide the initialRoute prop with a route object. A route object is used to describe each scene that your app navigates to. initialRoute represents the first route in your navigator.

import PropTypes from 'prop-types';
import React, { Component } from 'react';
import { NavigatorIOS, Text, TouchableHighlight, View } from 'react-native';

export default class NavigatorIOSApp extends Component {
  render() {
    return (
      <NavigatorIOS
        initialRoute={{
          component: MyScene,
          title: 'My Initial Scene',
        }}
        style={{flex: 1}}
      />
    );
  }
}

class MyScene extends Component {
  static propTypes = {
    title: PropTypes.string.isRequired,
    navigator: PropTypes.object.isRequired,
  }

  _onForward = () => {
    this.props.navigator.push({
      title: 'Scene',
    });
  }

  render() {
    return (
      <View>
        <Text>Current Scene: { this.props.title }</Text>
        <TouchableHighlight onPress={this._onForward}>
          <Text>Tap me to load the next scene</Text>
        </TouchableHighlight>
      </View>
    )
  }
}

In this code, the navigator renders the component specified in initialRoute, which in this case is MyScene. This component will receive a route prop and a navigator prop representing the navigator. The navigator's navigation bar will render the title for the current scene, "My Initial Scene".

You can optionally pass in a passProps property to your initialRoute. NavigatorIOS passes this in as props to the rendered component:

initialRoute={{
  component: MyScene,
  title: 'My Initial Scene',
  passProps: { myProp: 'foo' }
}}

You can then access the props passed in via {this.props.myProp}.

Handling Navigation

To trigger navigation functionality such as pushing or popping a view, you have access to a navigator object. The object is passed in as a prop to any component that is rendered by NavigatorIOS. You can then call the relevant methods to perform the navigation action you need:

class MyView extends Component {
  _handleBackPress() {
    this.props.navigator.pop();
  }

  _handleNextPress(nextRoute) {
    this.props.navigator.push(nextRoute);
  }

  render() {
    const nextRoute = {
      component: MyView,
      title: 'Bar That',
      passProps: { myProp: 'bar' }
    };
    return(
      <TouchableHighlight onPress={() => this._handleNextPress(nextRoute)}>
        <Text style={{marginTop: 200, alignSelf: 'center'}}>
          See you on the other nav {this.props.myProp}!
        </Text>
      </TouchableHighlight>
    );
  }
}

You can also trigger navigator functionality from the NavigatorIOS component:

class NavvyIOS extends Component {
  _handleNavigationRequest() {
    this.refs.nav.push({
      component: MyView,
      title: 'Genius',
      passProps: { myProp: 'genius' },
    });
  }

  render() {
    return (
      <NavigatorIOS
        ref='nav'
        initialRoute={{
          component: MyView,
          title: 'Foo This',
          passProps: { myProp: 'foo' },
          rightButtonTitle: 'Add',
          onRightButtonPress: () => this._handleNavigationRequest(),
        }}
        style={{flex: 1}}
      />
    );
  }
}

The code above adds a _handleNavigationRequest private method that is invoked from the NavigatorIOS component when the right navigation bar item is pressed. To get access to the navigator functionality, a reference to it is saved in the ref prop and later referenced to push a new scene into the navigation stack.

Navigation Bar Configuration

Props passed to NavigatorIOS will set the default configuration for the navigation bar. Props passed as properties to a route object will set the configuration for that route's navigation bar, overriding any props passed to the NavigatorIOS component.

_handleNavigationRequest() {
  this.refs.nav.push({
    //...
    passProps: { myProp: 'genius' },
    barTintColor: '#996699',
  });
}

render() {
  return (
    <NavigatorIOS
      //...
      style={{flex: 1}}
      barTintColor='#ffffcc'
    />
  );
}

In the example above the navigation bar color is changed when the new route is pushed.

Props

`initialRoute`

NavigatorIOS uses route objects to identify child views, their props, and navigation bar configuration. Navigation operations such as push operations expect routes to look like this the initialRoute.

Type	Required
object: {component: function,title: string,titleImage: Image.propTypes.source,passProps: object,backButtonIcon: Image.propTypes.source,backButtonTitle: string,leftButtonIcon: Image.propTypes.source,leftButtonTitle: string,leftButtonSystemIcon: Object.keys(SystemIcons),onLeftButtonPress: function,rightButtonIcon: Image.propTypes.source,rightButtonTitle: string,rightButtonSystemIcon: Object.keys(SystemIcons),onRightButtonPress: function,wrapperStyle: View.style,navigationBarHidden: bool,shadowHidden: bool,tintColor: string,barTintColor: string,barStyle: enum('default', 'black'),titleTextColor: string,translucent: bool}	Yes

Type

Required

object: {component: function,title: string,titleImage: Image.propTypes.source,passProps: object,backButtonIcon: Image.propTypes.source,backButtonTitle: string,leftButtonIcon: Image.propTypes.source,leftButtonTitle: string,leftButtonSystemIcon: Object.keys(SystemIcons),onLeftButtonPress: function,rightButtonIcon: Image.propTypes.source,rightButtonTitle: string,rightButtonSystemIcon: Object.keys(SystemIcons),onRightButtonPress: function,wrapperStyle: View.style,navigationBarHidden: bool,shadowHidden: bool,tintColor: string,barTintColor: string,barStyle: enum('default', 'black'),titleTextColor: string,translucent: bool}

Yes

`barStyle`

The style of the navigation bar. Supported values are 'default', 'black'. Use 'black' instead of setting barTintColor to black. This produces a navigation bar with the native iOS style with higher translucency.

Type	Required
enum('default', 'black')	No

`barTintColor`

The default background color of the navigation bar.

Type	Required
string	No

`interactivePopGestureEnabled`

Boolean value that indicates whether the interactive pop gesture is enabled. This is useful for enabling/disabling the back swipe navigation gesture.

If this prop is not provided, the default behavior is for the back swipe gesture to be enabled when the navigation bar is shown and disabled when the navigation bar is hidden. Once you've provided the interactivePopGestureEnabled prop, you can never restore the default behavior.

Type	Required
bool	No

`itemWrapperStyle`

The default wrapper style for components in the navigator. A common use case is to set the backgroundColor for every scene.

Type	Required
View.style	No

`navigationBarHidden`

Boolean value that indicates whether the navigation bar is hidden by default.

Type	Required
bool	No

`shadowHidden`

Boolean value that indicates whether to hide the 1px hairline shadow by default.

Type	Required
bool	No

`tintColor`

The default color used for the buttons in the navigation bar.

Type	Required
string	No

`titleTextColor`

The default text color of the navigation bar title.

Type	Required
string	No

`translucent`

Boolean value that indicates whether the navigation bar is translucent by default. When true any screens loaded within the navigator will sit below the status bar and underneath the navigation bar. To have screens render below the navigation bar set to false.

Type	Required
bool	No
