class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      object1: { name: 'Object 1', value: 1 },
      object2: { name: 'Object 2', value: 2 }
    };
  }

  // ...
}

class MyComponent extends React.Component {
  // ...

  updateObjects = () => {
    this.setState(prevState => ({
      object1: { ...prevState.object1, value: 3 },
      object2: { ...prevState.object2, value: 4 }
    }));
  }

  // ...
}

class MyComponent extends React.Component {
  // ...

  render() {
    return (
      <div>
        <button onClick={this.updateObjects}>更新对象状态</button>
      </div>
    );
  }
}

this.setState(prevState => ({
  object1: { ...prevState.object1, value: 3 },
  object2: { ...prevState.object2, value: 4 }
