在哪里调用react组件中的方法？

class MyComponent extends React.Component {
  handleClick() {
    // 处理点击事件的逻辑
  }

  render() {
    return (
      <button onClick={this.handleClick}>点击我</button>
    );
  }
}

class ParentComponent extends React.Component {
  handleClick() {
    // 处理点击事件的逻辑
  }

  render() {
    return (
      <ChildComponent onClick={this.handleClick} />
    );
  }
}

class ChildComponent extends React.Component {
  render() {
    return (
      <button onClick={this.props.onClick}>点击我</button>
    );
  }
}

import React, { useState } from 'react';

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

  function handleClick() {
    setCount(count + 1);
  }

  return (
    <div>
      <p>点击次数：{count}</p>
      <button onClick={handleClick}>点击我</button>
    </div>
  );
}
