Summary: **Motivation** Fix an issue (#15389) where `TVEventHandler` would not work when a modal was visible. The solution adds the gesture recognizers from the native `RCTTVRemoteHandler` to the native modal view (except for the menu button recognizer, which still needs special handling in modals). This PR also fixes some breakages in compiling React Native for tvOS. **Test plan** Compilation fixes should enable tvOS compile test to pass in Travis CI. The modal fix can be tested with the following component, modified from the original source in #15389 . ``` javascript import React, { Component } from 'react'; import ReactNative from 'ReactNative'; import { Text, View, StyleSheet, TouchableHighlight, TVEventHandler, Modal, } from 'react-native'; export default class Events extends Component { constructor(props) { super(props); this.state = { modalVisible: false, }; this._tvEventHandler = new TVEventHandler(); } _enableTVEventHandler() { this._tvEventHandler.enable(this, (cmp, evt) => { const myTag = ReactNative.findNodeHandle(cmp); console.log('Event.js TVEventHandler: ', evt.eventType); // if (evt.eventType !== 'blur' && evt.eventType !== 'focus') { // console.log('Event.js TVEventHandler: ', evt.eventType); // } }); } _disableTVEventHandler() { if (this._tvEventHandler) { this._tvEventHandler.disable(); delete this._tvEventHandler; } } componentDidMount() { this._enableTVEventHandler(); } componentWillUnmount() { this._disableTVEventHandler(); } _renderRow() { return ( <View style={styles.row}> { Array.from({ length: 7 }).map((_, index) => { return ( <TouchableHighlight key={index} onPress={() => { this.setState({ modalVisible: !this.state.modalVisible }); }} > <View style={styles.item}> <Text style={styles.itemText}>{ index }</Text> </View> </TouchableHighlight> ); }) } </View> ); } onTVEvent(cmp, evt) { console.log('Modal.js TVEventHandler: ', evt.eventType); } hideModal() { this.setState({ modalVisible: false }); } render() { return ( <View style={styles.container}> <Modal visible={this.state.modalVisible} onRequestClose={() => this.hideModal()}> <View style={styles.modal}> { this._renderRow() } { this._renderRow() } </View> </Modal> { this._renderRow() } { this._renderRow() } </View> ); } } const styles = StyleSheet.create({ container: { flex: 1, backgroundColor: 'darkslategrey', }, row: { flexDirection: 'row', padding: 30, }, item: { width: 200, height: 100, borderColor: 'cyan', borderWidth: 2, margin: 30, alignItems: 'center', justifyContent: 'center', }, itemText: { fontSize: 40, color: 'cyan', }, modal: { flex: 1, backgroundColor: 'steelblue', }, }); ``` **Release Notes** After this change, the `onRequestClose` property will be required for a `Modal` in Apple TV.

App templates
This folder contains basic app templates. These get expanded by 'react-native init' when creating a new app to make it easier for anyone to get started.
Chat Example
This is an example React Native app demonstrates ListViews, text input and navigation between a few screens.
Purpose
One problem with React Native is that it is not trivial to get started: react-native init
creates a very simple app that renders some text. Everyone then has to figure out how to do very basic things such as adding a list of items fetched from a server, navigating to a screen when a list item is tapped, or handling text input.
This app is a template used by react-native init
so it is easier for anyone to get up and running quickly by having an app with a few screens, a ListView
and a TextInput
that works well with the software keyboard.
Best practices
Another purpose of this app is to define best practices such as:
- The folder structure of a standalone React Native app
- A style guide for JavaScript and React - for this we use the AirBnb style guide
- Naming conventions
We need your feedback to settle on a good set of best practices. Have you built React Native apps? If so, please use the issues in the repo mkonicek/ChatExample to discuss what you think are the best practices that this example should be using.
Running the app locally
