/**
|
||
|
|
* 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.
