如何将使用默认formik挂钩的功能组件转换为类组件

import React, { Component } from 'react';

class MyForm extends Component {
  render() {
    return (
      <div>
        {/* Formik form components */}
      </div>
    );
  }
}

export default MyForm;

import { Formik, Form, Field, ErrorMessage } from 'formik';

class MyForm extends Component {
  render() {
    return (
      <div>
        <Formik
          initialValues={{ /* 初始值 */ }}
          onSubmit={/* 提交表单的处理函数 */}
          validationSchema={/* 表单验证规则 */}
        >
          <Form>
            {/* 表单组件 */}
          </Form>
        </Formik>
      </div>
    );
  }
}

<Field type="text" name="fieldName" />

<ErrorMessage name="fieldName" component="div" />

class MyForm extends Component {
  handleSubmit = (values, actions) => {
    // 处理表单提交逻辑
  }

  render() {
    return (
      <div>
        <Formik
          initialValues={{ /* 初始值 */ }}
          onSubmit={this.handleSubmit}
          validationSchema={/* 表单验证规则 */}
        >
          {/* 表单组件 */}
        </Formik>
      </div>
    );
  }
}
