## zh-CN

延迟显示 loading 效果。当 spinning 状态在 `delay` 时间内结束，则不显示 loading 状态。

## en-US

Specifies a delay for loading state. If `spinning` ends during delay, loading status won't appear.

```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);
  };
  const container = (
    <Alert
      message="Alert message title"
      description="Further details about the context of this alert."
      type="info"
    />
  );

  return (
    <div>
      <Spin spinning={loading} delay={500}>
        {container}
      </Spin>
      <div style={{ marginTop: 16 }}>
        Loading state：
        <Switch checked={loading} onChange={toggle} />
      </div>
    </div>
  );
};

export default App;
```
