将相同类型的多个用户控件添加到页面

import React, { Component } from 'react';

class UserControl extends Component {
  constructor(props) {
    super(props);
    this.state = {
      // 初始化组件状态
    };
  }

  render() {
    return (
      // 渲染组件
    );
  }
}

export default UserControl;

import React, { Component } from 'react';
import UserControl from './UserControl';

class ParentComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      userControls: [
        { id: 1, name: 'User 1' },
        { id: 2, name: 'User 2' },
        { id: 3, name: 'User 3' },
      ],
    };
  }

  render() {
    return (
      <div>
        {this.state.userControls.map((userControl) => (
          <UserControl key={userControl.id} name={userControl.name} />
        ))}
      </div>
    );
  }
}

export default ParentComponent;
