## zh-CN

可以直接把内容内嵌到 `Spin` 中，将现有容器变为加载状态。

## en-US

Embedding content into `Spin` will set it into loading state.

```tsx
import { Alert, Spin, Switch } from 'antd';
import React, { useState } from 'react';

const App: React.FC = () => {
  const [loading, setLoading] = useState(false);

  const toggle = (checked: boolean) => {
    setLoading(checked);
  };

  return (
    <div>
      <Spin spinning={loading}>
        <Alert
          message="Alert message title"
          description="Further details about the context of this alert."
          type="info"
        />
      </Spin>
      <div style={{ marginTop: 16 }}>
        Loading state：
        <Switch checked={loading} onChange={toggle} />
      </div>
    </div>
  );
};

export default App;
```
