javascript - iOS9: Try to open app via scheme if possible, or redirect to app store otherwise -

my question ios9 only!

i have html landing page, , try redirect user to app via url scheme if app installed, or redirect appstore otherwise.

my code is:

document.addeventlistener("domcontentloaded", function(event) {    var body = document.getelementsbytagname('body')[0];   body.onclick = function () {     openapp();   }; });  var timeout;  function preventpopup() {      cleartimeout(timeout);     timeout = null;     window.removeeventlistener('pagehide', preventpopup); }  function openapp(appinstanceid, platform) {    window.addeventlistener('pagehide', preventpopup);   document.addeventlistener('pagehide', preventpopup);    // create iframe   var iframe = document.createelement("iframe");   document.body.appendchild(iframe);   iframe.setattribute("style", "display:none;");   iframe.src = 'myscheme://launch?var=val';    var timeouttime = 1000;   timeout = settimeout(function () {      document.location = 'https://itunes.apple.com/app/my-app';    }, timeouttime); } 

the problem iframe trick doesn't work in safari ios9.

any idea why?

my iframe trick based on this answer.

the iframe trick no longer works -- guess apple knows encourage more developers implement universal links, more quickly.

you can still set window.location='your-uri-scheme://'; , fallback app store after 500ms. there "dance" between popups if take approach, @ branch (we fallback if universal links don't work).

window.location = 'your-uri-scheme://'; // result in error message if app not installed settimeout(function() {    // link app store should go here -- fires if deep link fails                    window.location = "https://itunes.apple.com/us/app/myapp/id123456789?ls=1&mt=8"; }, 500); 

i wish had better answer you. ios 9 more limited.
