Follow the iOS build setup guide in the docs, which involves adding the WeChat SDK via CocoaPods or manual linking, and configuring the app ID. Ensure you have Xcode and the correct SDK version installed.

Question 2

Why does sharing an image URL fail in react-native-wechat?

Question 3

react-native-wechat vs other WeChat libraries: which one should I use?

Question 5

Is react-native-wechat compatible with Expo?

Accepted Answer

No, it requires linking native modules, so it's not compatible with the Expo Go client. You would need to eject to a bare workflow or use a development build to integrate it.

Use the shareToSession method with type 'file', providing the filePath and fileExtension. Save the file locally using a package like react-native-fs, as detailed in the README examples for both iOS and Android paths.
