react-native-navigation

React Native Navigation

App-wide support for 100% native navigation with potential isolation support. For iOS, this package is a wrapper around react-native-controllers which provides a simplified more abstract API. This abstract API will be unified with the Android solution which is still work in progress.

Installation - iOS

• In your project folder run npm install react-native-navigation --save

• Add the native files of the dependency react-native-controllers to your Xcode project:

  • In Xcode, in Project Navigator (left pane), right-click on the Libraries > Add files to [project name]. Add ./node_modules/react-native-controllers/ios/ReactNativeControllers.xcodeproj (screenshots)

  • In Xcode, in Project Navigator (left pane), click on your project (top) and select the Build Phases tab (right pane). In the Link Binary With Libraries section add libReactNativeControllers.a (screenshots)

  • In Xcode, in Project Navigator (left pane), click on your project (top) and select the Build Settings tab (right pane). In the Header Search Paths section add $(SRCROOT)/../node_modules/react-native-controllers/ios. Make sure on the right to mark this new path recursive (screenshots)

• In Xcode, under your project files, modify AppDelegate.m according to this example

• Make sure you are using react-native version >= 0.19.0

Installation - Android

Coming soon, not yet supported

Usage

If you don't like reading, just jump into the fully working example project.

Step 1 - Change the way your app starts

This would normally go in your index.ios.js

import { Navigation } from 'react-native-navigation';

// import the components for your root screens (or the packager will not bundle them)
// they all need to be registered with Navigation.registerScreen
import './FirstTabScreen';
import './SecondTabScreen';

// start the app
Navigation.startTabBasedApp({
  tabs: [
    {
      label: 'One',
      screen: 'example.FirstTabScreen',
      icon: require('../img/one.png'),
      selectedIcon: require('../img/one_selected.png'),
      title: 'Screen One'
    },
    {
      label: 'Two',
      screen: 'example.SecondTabScreen',
      icon: require('../img/two.png'),
      selectedIcon: require('../img/two_selected.png'),
      title: 'Screen Two'
    }
  ]
});

Step 2 - Slightly modify your screen components

Every screen that you want to be able to place in a tab, push to the navigation stack or present modally needs to follow two basic conventions:

1. Normally your React components extend React.Component, in order to get access to the navigator instance you need to extend Screen instead.

2. You need to register your component since it's displayed as a separate React root. Register a unique ID with Navigation.registerScreen.

Note: Since your screens will potentially be bundled with other packages, your registered name must be unique! Follow a namespacing convention like packageName.ScreenName.

import { Navigation, Screen } from 'react-native-navigation';

class ExampleScreen extends Screen {
  static navigatorStyle = {}; // style the navigator for this screen (optional)
  constructor(props) {
    super(props);
  }
  render() {
    return (
      <View style={styles.container}>...</View>
    );
  }
}

// register all screens with Navigation.registerScreen
Navigation.registerScreen('example.ScreenOne', () => ExampleScreen);

Top Level API

Navigation

import { Navigation } from 'react-native-navigation';

• registerScreen(screenID, generator)

Every screen used must be registered with a unique name.

Navigation.registerScreen('example.FirstTabScreen', () => FirstTabScreen);

• startTabBasedApp(params)

Change your app root into an app based on several tabs (usually 2-5), a very common pattern in iOS (like Facebook app or the iOS Contacts app). Every tab has its own navigation stack with a native nav bar.

Navigation.startTabBasedApp({
  tabs: [
    {
      label: 'One',
      screen: 'example.FirstTabScreen',
      icon: require('../img/one.png'),
      selectedIcon: require('../img/one_selected.png'),
      title: 'Screen One'
    },
    {
      label: 'Two',
      screen: 'example.SecondTabScreen',
      icon: require('../img/two.png'),
      selectedIcon: require('../img/two_selected.png'),
      title: 'Screen Two'
    }
  ]
});

• startSingleScreenApp(params)

Change your app root into an app based on a single screen (like the iOS Calendar or Settings app). The screen will receive its own navigation stack with a native nav bar

Navigation.startSingleScreenApp({
  screen: {
    screen: 'example.WelcomeScreen',
    title: 'Welcome'
  }
});

• showModal(params = {})

Show a screen as a modal.

Navigation.showModal({
  title: "Modal",
  screen: "example.ModalScreen"
});

• dismissModal(params = {})

Dismiss the current modal.

Navigation.dismissModal();

Screen API

This API is relevant when in a screen context - it allows a screen to push other screens, pop screens, change its navigator style, etc. Access to this API is available through the navigator object. When your screen components extend Screen, they have this.navigator available and initialized.

• push(params)

Push a new screen into this screen's navigation stack.

this.navigator.push({
  screen: 'example.ScreenThree', // unique ID registered with Navigation.registerScreen
  title: undefined, // navigation bar title of the pushed screen (optional)
  passProps: {}, // simple serializable object that will pass as props to the pushed component (optional)
  animated: true, // does the push have transition animation or does it happen immediately (optional)
  backButtonTitle: undefined, // override the back button title (optional)
  navigatorStyle: {} // override the navigator style for the pushed screen (optional)
});

• pop(params = {})

Pop the top screen from this screen's navigation stack.

this.navigator.pop({
  animated: true // does the pop have transition animation or does it happen immediately (optional)
});

• showModal(params = {})

Show a screen as a modal.

this.navigator.showModal({
  title: "Modal",
  screen: "example.ModalScreen"
});

• dismissModal(params = {})

Dismiss the current modal.

this.navigator.dismissModal();

Styling the navigator

You can style the navigator appearance and behavior by passing a navigatorStyle object. This object can be passed when the screen is originally created; can be defined per-screen in the static navigatorStyle = {}; on Screen; and can be overridden when a screen is pushed.

All supported styles are defined here.
