Consider the question:

Typically, we develop an app that has an Android version and an iOS version.

But only one QR code? What do we do?

How to let iOS user scan qr code download iOS version, android user scan QR code to download to Android version?

Implementation ideas:

    • First of all, we need to create a new HTML file, through JavaScript to determine the user's mobile phone system (iOS or Android), after judging, according to the different mobile system, jump to different links to download.
    • We then use the address of this HTML file to generate a two-dimensional code image.
    • Finally, the user can scan a two-dimensional code image for the corresponding download.

the code:down.html
