How to save image to Camera Roll using Expo?

Question

I'm creating an app using Expo to take picture, I'm already possible to save pictures to FileSystem.documentDirectory, but this is not what I want.

我试图将图像保存到 Camera Roll using code like this:

import { CameraRoll } from 'react-native';
...
...
await CameraRoll.saveToCameraRoll(photo.uri);

但它返回一个警告我使用react-native-cameraroll而不是react-native. But as I see in the document of the react-native-cameraroll, it's seems not supporting Expo.

有没有办法将图像保存到相机胶卷中Expo？

Answer 1

我找到了解决这一点，而不是使用CameraRoll您可以使用MediaLibrary来MediaLibrary.saveToLibraryAsync(localUri)
