如何在react native中转换方法中的名称

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      value: ''
    };
  }

  handleChange = (text) => {
    this.setState({ value: text });
  }

  render() {
    return (
      <TextInput
        value={this.state.value}
        onChangeText={this.handleChange}
      />
    );
  }
}

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      value: ''
    };
    this.handleChange = this.handleChange.bind(this);
  }

  handleChange(text) {
    this.setState({ value: text });
  }

  render() {
    return (
      <TextInput
        value={this.state.value}
        onChangeText={this.handleChange}
      />
    );
  }
}
