An app that I recently submitted to the Apple App Store was rejected, due to the following reason: If the WeChat app is not installed and the user clicks a button "Login with WeChat", a dialog pops up telling the user they must install the WeChat app to log in with it. (if the app is installed, the user is bumped over to the WeChat app to finish login)
Apple suggested that we instead use a Web View to log the user in via WeChat, however the WeChat guide for mobile login states that mobile apps must log in through the WeChat app:

I'm a little confused here because a previous app I had submitted was approved using this setup. In the app I'm currently trying to submit, the user is able to skip WeChat login if they wish, so WeChat installation is not required to use the app. However, it would be nice to be able to tell the user that WeChat is a login option, and that they need to install the WeChat app if they'd like to use it as a login option.
Does anyone know if it's allowable and/or possible (wrt WeChat's system) for an iOS app to log a user in via WeChat using a Web View? It seems that telling the user that WeChat is an available login option might not be possible otherwise...
To answer your question, We don't have any other Webview options to login with Wechat. (as of dated Jan 2018)
I had the same rejection from Apple some time back. After a lot of front and back questions and answers with Apple team, We finally hide the button to login with Wechat when Wechat App is not installed and the review passed. Most of the Chinese apps following the same method AFAIK.
Wechat iOS framework does provide an option to check app installed or not.
