创建编辑表单时，useEffect未更新react-hook-form的默认值

import React, { useEffect } from 'react';
import { useForm } from 'react-hook-form';

const MyForm = () => {
  const { register, setValue } = useForm();

  useEffect(() => {
    // 模拟从后端获取表单数据
    const fetchData = async () => {
      const response = await fetch('API_URL');
      const data = await response.json();
      
      // 使用setValue方法更新react-hook-form的默认值
      setValue('name', data.name);
      setValue('email', data.email);
    };

    fetchData();
  }, []);

  return (
    <form>
      <input {...register('name')} />
      <input {...register('email')} />
      {/* 其他表单字段 */}
    </form>
  );
};

export default MyForm;
