</html> 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
