Keyboard events for react-native

How to move a view when the keyboard shows up
var React = require('react-native');  
var KeyboardEvents = require('react-native-keyboardevents');  
var KeyboardEventEmitter = KeyboardEvents.Emitter;

class YourComponent extends React.Component {

  constructor(props, context) {
    super(props, context);

    this.state = {
      keyboardSpace: 0
    };

    this.updateKeyboardSpace = this.updateKeyboardSpace.bind(this);
    this.resetKeyboardSpace = this.resetKeyboardSpace.bind(this);
  }

  updateKeyboardSpace(frames) {
    this.setState({keyboardSpace: frames.end.height});
  }

  resetKeyboardSpace() {
    this.setState({keyboardSpace: 0});
  }

  componentDidMount() {
    KeyboardEventEmitter.on(KeyboardEvents.KeyboardDidShowEvent, this.updateKeyboardSpace);
    KeyboardEventEmitter.on(KeyboardEvents.KeyboardWillHideEvent, this.resetKeyboardSpace);
  }

  componentWillUnmount() {
    KeyboardEventEmitter.off(KeyboardEvents.KeyboardDidShowEvent, this.updateKeyboardSpace);
    KeyboardEventEmitter.off(KeyboardEvents.KeyboardWillHideEvent, this.resetKeyboardSpace);
  }

  render() {
    // create your content here
    return (
      <View>
      // add your content here

      // when the keyboard is shown, this spacer will push up all your other content
      <View style={{height: this.state.keyboardSpace}}></View>
      </View>
    );
  }
}
