Is it possible to register a http+domain-based URL Scheme for iPhone apps, like YouTube and Maps?

I\'d like to have iOS to open URLs from my domain (e.g. http://martijnthe.nl) with my app whenever the app is installed on the phone, and with Mobile Safari in case it is no

    In iOS9 Apple finally introduced the possibility to register your app to handle certain http:// URLs: Universal Links.

    A very rough explanation of how it works:

    • You declare interest in opening http:// URLs for certain domains (web urls) in your app.
    • On the server of the specified domains you have to indicate which URLs to open in which app that has declared interest in opening URLs from the server's domain.
    • The iOS URL loading service checks all attempts to open http:// URLs for a setup as explained above and opens the correct app automatically if installed; without going through Safari first...

    This is the cleanest way to do deep linking on iOS, unfortunately it works only in iOS9 and newer...

    I found that the selected answer works for the browser apps but I was having issues with the code working in non browser apps that implement a UIWebView.

    The problem for me was a user on the Twitter app would click a link that would take them to my site through a UIWebView in the Twitter app. Then when they clicked a button from my site Twitter tries to be fancy and only complete the window.location if the site is reachable. So what happens is a UIAlertView pops up saying are you sure you want to continue and then immediately redirects to the App Store without a second popup.

    My solution involves iframes. This avoids the UIAlertView being presented allowing for a simple and elegant user experience.

    jQuery

    var redirect = function (location) {
    $('body').append($('<iframe></iframe>').attr('src', location).css({
        width: 1,
        height: 1,
        position: 'absolute',
        top: 0,
        left: 0
    }));
};

setTimeout(function () {
    redirect('http://itunes.apple.com/app/id');
}, 25);

redirect('custom-uri://');

    Javascript

    var redirect = function (location) {
    var iframe = document.createElement('iframe');
    iframe.setAttribute('src', location);
    iframe.setAttribute('width', '1px');
    iframe.setAttribute('height', '1px');
    iframe.setAttribute('position', 'absolute');
    iframe.setAttribute('top', '0');
    iframe.setAttribute('left', '0');
    document.documentElement.appendChild(iframe);
    iframe.parentNode.removeChild(iframe);
    iframe = null;
};

setTimeout(function () {
    redirect('http://itunes.apple.com/app/id');
}, 25);

redirect('custom-uri://');

    EDIT:

    Add position absolute to the iframe so when inserted there isn't a random bit of whitespace at the bottom of the page.

    Also it's important to note that I have not found a need for this approach with Android. Using window.location.href should work fine.

    You can't, as far as I know, make the entire OS understand an http:+domain URL. You can only register new schemes (I use x-darkslide: in my app). If the app is installed, Mobile Safari will launch the app correctly.

    However, you would have to handle the case where the app isn't installed with a "Still here? Click this link to download the app from iTunes." in your web page.

    If you add an iframe on your web page with the src set to custom scheme for your App, iOS will automatically redirect to that location in the App. If the app is not installed, nothing will happen. This allows you to deep link into the App if it is installed, or redirect to the App Store if it is not installed.

    For example, if you have the twitter app installed, and navigate to a webpage containing the following markup, you would be immediately directed to the app.

    <!DOCTYPE html>
<html>
    <head>
    <title>iOS Automatic Deep Linking</title>
    </head>
    <body>
        <iframe src="twitter://" width="0" height="0"></iframe>
        <p>Website content.</p>
    </body>
</html>

    Here is a more thorough example that redirects to the App store if the App is not installed:

    <!DOCTYPE html>
<html>
    <head>
    <title>iOS Automatic Deep Linking</title>
    <script src='//code.jquery.com/jquery-1.11.2.min.js'></script>
    <script src='//mobileesp.googlecode.com/svn/JavaScript/mdetect.js'></script>
    <script>
      (function ($, MobileEsp) {
        // On document ready, redirect to the App on the App store.
        $(function () {
          if (typeof MobileEsp.DetectIos !== 'undefined' && MobileEsp.DetectIos()) {
            // Add an iframe to twitter://, and then an iframe for the app store
            // link. If the first fails to redirect to the Twitter app, the
            // second will redirect to the app on the App Store. We use jQuery
            // to add this after the document is fully loaded, so if the user
            // comes back to the browser, they see the content they expect.
            $('body').append('<iframe class="twitter-detect" src="twitter://" />')
              .append('<iframe class="twitter-detect" src="itms-apps://itunes.com/apps/twitter" />');
          }
        });
      })(jQuery, MobileEsp);
    </script>
    <style type="text/css">
      .twitter-detect {
        display: none;
      }
    </style>
    </head>
    <body>
    <p>Website content.</p>
    </body>
</html>

    In seeking to fix the problem of pop-up, I discovered that Apple had a way around this concern.

    Indeed, when you click on this link, if you installed the application, it is rerouted to it; otherwise, you will be redirected to the webpage, without any pop-up.

    BUILDING Again on Nathan and JB's Answer:

    How To Launch App From url w/o Extra Click If you prefer a solution that does not include the interim step of clicking a link, the following can be used. With this javascript, I was able to return a Httpresponse object from Django/Python that successfully launches an app if it is installed or alternatively launches the app store in the case of a time out. Note I also needed to adjust the timeout period from 500 to 100 in order for this to work on an iPhone 4S. Test and tweak to get it right for your situation.

    <html>
<head>
   <meta name="viewport" content="width=device-width" />
</head>
<body>

<script type="text/javascript">

// To avoid the "protocol not supported" alert, fail must open another app.
var appstorefail = "itms://itunes.apple.com/us/app/facebook/id284882215?mt=8&uo=6";

var loadedAt = +new Date;
setTimeout(
  function(){
    if (+new Date - loadedAt < 2000){
      window.location = appstorefail;
    }
  }
,100);

function LaunchApp(){
  window.open("unknown://nowhere","_self");
};
LaunchApp()
</script>
</body>
</html>
