my APP installation package can only be displayed by scanning the code in the browser. Wechat of iOS and Android scanned the page and left the page blank untouched.

question 1 Wechat"s built-in browser iOS and Android scan code cannot be downloaded and installed
question 2 Wechat"s built-in browser scan iOS I need to add a prompt box indicating that Wechat is about to leave and open app Stroe download is actually a direct installation of
the case to be copied
iOS 2 2

the key point is that neither its APP package nor my APP package is available on the shelves because both of them need to be downloaded. Settings-Trust to open

what result do you expect? What is the error message actually seen?

consistent with the reference case I provided, scan the iOS prompt box of Wechat"s built-in browser, and then download and install it directly
scan the code in other external browsers and download directly

Today"s update on 2018-8-9: tested the reference materials given by group friends: https://blog.csdn.net/qian_me. (title: itms-services protocol, install IOS applications directly through AppStore,)

but the Safari test cannot open the web page
