NavigatorIOS #

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 Navigator for a similar solution for your cross-platform needs, or check out react-native-navigation, a component that aims to provide native navigation on both iOS and Android.

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 React, { Component, PropTypes } from 'react';
import { NavigatorIOS, Text } 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 ' + nextIndex,
    });
  }

  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 #

barTintColor string #

The default background color of the navigation bar.

initialRoute {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: [object Object], navigationBarHidden: bool, shadowHidden: bool, tintColor: string, barTintColor: string, titleTextColor: string, translucent: bool} #

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.

interactivePopGestureEnabled bool #

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.

itemWrapperStyle View#style #

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

navigationBarHidden bool #

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

shadowHidden bool #

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

tintColor string #

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

titleTextColor string #

The default text color of the navigation bar title.

translucent bool #

Boolean value that indicates whether the navigation bar is translucent by default
