在UseEffect中设置状态后如何更新状态？

import React, { useState, useEffect } from 'react';

function Example() {
  const [count, setCount] = useState(0);

  useEffect(() => {
    // 在UseEffect中设置状态
    setCount(1);
  }, []);

  // 更新状态
  const updateCount = () => {
    setCount(count + 1);
  };

  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={updateCount}>Update Count</button>
    </div>
  );
}

export default Example;
