ios - Deep linking an app in PHP is not working -


i have webpage needs check see if app exists using deep link, doesn't seem work should. have tried following things.

  1. using redirect in php (doesn't work)

header('location: exampleapp://param=test');

  1. using redirect using javascript (doesn't work)

    var appurl = 'exampleapp://param=test'; var appstore = 'https://itunes.apple.com/us/app/...';  var timeout; function preventpopup() {   cleartimeout(timeout);   timeout = null;   window.removeeventlistener('pagehide', preventpopup); } function startapp() {     window.location = appurl;     timeout = settimeout(function(){     if(confirm('you not seem have app installed, want go download now?')){         document.location = appstore;         }     }, 100);     window.addeventlistener('pagehide', preventpopup); }  // app start called in onload

  2. same above replace the line window.location = appurl; document.getelementbyid('deeplink').click(); , adding link in html's webpage. (works) <a id="deeplink" href="exampleapp://param=test">deep link</a>

is there reason why can't redirect using header in php?

the php version doesn't work, because of way http works. http protocol doesn't specify should work redirect different protocol within "location:" header. there nothing specific php here, it's http issue.

the javascript version doesn't work because wanted set windows location. , window cannot show contents of "exampleapp://..." . want link open when user clicks on it. instead of using window.location may use document.location.href. should work.

another problem: in code write exampleapp:// in 1) , 2). , in 3) write testapp:// - make sure use same url in 3 cases, can sure url can work eventually..
