/**
 * Note: iOS only
 *
 * A component which enables customization of the keyboard input accessory view.
 * The input accessory view is displayed above the keyboard whenever a TextInput
 * has focus. This component can be used to create custom toolbars.
 *
 * To use this component wrap your custom toolbar with the
 * InputAccessoryView component, and set a nativeID. Then, pass that nativeID
 * as the inputAccessoryViewID of whatever TextInput you desire. A simple
 * example:
 *
 * ```ReactNativeWebPlayer
 * import React, { Component } from 'react';
 * import { AppRegistry, TextInput, InputAccessoryView, Button } from 'react-native';
 *
 * export default class UselessTextInput extends Component {
 *   constructor(props) {
 *     super(props);
 *     this.state = {text: 'Placeholder Text'};
 *   }
 *
 *   render() {
 *     const inputAccessoryViewID = "uniqueID";
 *     return (
 *       <View>
 *         <ScrollView keyboardDismissMode="interactive">
 *           <TextInput
 *             style={{
 *               padding: 10,
 *               paddingTop: 50,
 *             }}
 *             inputAccessoryViewID=inputAccessoryViewID
 *             onChangeText={text => this.setState({text})}
 *             value={this.state.text}
 *           />
 *         </ScrollView>
 *         <InputAccessoryView nativeID=inputAccessoryViewID>
 *           <Button
 *             onPress={() => this.setState({text: 'Placeholder Text'})}
 *             title="Reset Text"
 *           />
 *         </InputAccessoryView>
 *       </View>
 *     );
 *   }
 * }
 *
 * // skip this line if using Create React Native App
 * AppRegistry.registerComponent('AwesomeProject', () => UselessTextInput);
 * ```
 *
 * This component can also be used to create sticky text inputs (text inputs
 * which are anchored to the top of the keyboard). To do this, wrap a
 * TextInput with the InputAccessoryView component, and don't set a nativeID.
 * For an example, look at InputAccessoryViewExample.js in RNTester.
