看了下 usb-c 线的 spec 貌似没问题「 all certified USB C cables support 60W charging 」

看来还是只有靠捷径了，少数派也有个帖子「巧用快捷指令清理 iOS 剪贴板」

我又搜了一下，找到了如下这段描述

```
Secure Paste
Let’s start with a new feature that went totally under the radar. Secure Paste in iOS 15 lets you copy text or other content from one app and paste it to another in a more secure way.

A couple of years ago, any iOS app could access the clipboard and read sensitive information that you’d copied, perhaps from a password manager. However, apps won’t get access to whatever is on the clipboard in iOS 15 until the moment you hit the Paste button.
```

但也没有找到相应设置的地方，那这是默认打开的？但的确如 ls 所说，一些 app 进入后还是会弹出"pasted from..."的消息，而且我测了下，的确是读到了剪切板中的内容的

好了！我把拆开的 Video 组建用 React.memo 包住就可以了！谢谢！

@coderfuns 我将他们拆开了还是一样问题...

```jsx
import React, { useState } from 'react';

function CurrentTime({ currentTime }) {
return <p>{currentTime}</p>;
}

function Player({ video, onTimeUpdate }) {
return (
<video
controls
onTimeUpdate={(e) => onTimeUpdate(e.target.currentTime)}
src={URL.createObjectURL(video)}
width="250"
/>
);
}

export default function App() {
const [video, setVideo] = useState();
const [currentTime, setCurrentTime] = useState();

return (
<>
<input type="file" onChange={(e) => setVideo(e.target.files?.item(0))} />
{video && <Player video={video} onTimeUpdate={setCurrentTime} />}
<CurrentTime currentTime={currentTime} />
</>
);
}

```

不好意思，“向公众" 把我看笑了 😂

顺带想问问，有没有办法能够方便看到数据库的变化呢？我想的是，监控变化，跑去页面做个操作，然后看数据库发生了什么变化，从而理解该部分的逻辑。

@Rocketer 说得太好了！
