| /** | ||
| * 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. | ||
