react中字段响应式

class中用法:
import React, { Component } from 'react'
export default class Index extends Component<any, any> {

  constructor(props) {
    super(props)
    this.state = {
      settingInfo: {},
    }
  }

  async componentDidMount() {
    let settingInfo = await Service.getSettingInfo(this.context, {
      page_session_id: 'kUeombnhdm',
    })
    this.setState({ settingInfo: settingInfo })
  }

  render() {
    return <View style={{ marginTop: 50 }}>{this.state.settingInfo.errorMsg}</View>
  }
}

function中用法:
import React, { useEffect, useState } from 'react'

const Index = () => {
  const [driver, setDriver] = useState(false)
  useEffect(() => {
    setDriver(false)
  }, [])
  return <View className={styles.backgroundIcon}>{driver}</View>
}

export default Index
