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

iosiphoneurl

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 not.

I read it is possible to create a unique protocol suffix for this and register it in the Info.plist, but Mobile Safari will give an error in case the app is not installed.

What would be a workaround?

One idea:

1) Use http:// URLs that open in any desktop browser and render the service through the browser

2) Check the User-Agent and in case it's Mobile Safari, open a myprotocol:// URL to (attempt) to open the iPhone app and have it open Mobile iTunes to the download of the app in case the attempt fails

Not sure if this will work… suggestions? Thanks!

I think the least intrusive way of doing this is as follows:

Check if the user-agent is that of an iPhone/iPod Touch
Check for an appInstalled cookie
If the cookie exists and is set to true, set window.location to your-uri:// (or do the redirect server side)
If the cookie doesn't exist, open a "Did you know Your Site Name has an iPhone application?" modal with a "Yep, I've already got it", "Nope, but I'd love to try it", and "Leave me alone" button.
1. The "Yep" button sets the cookie to true and redirects to your-uri://
2. The "Nope" button redirects to "http://itunes.com/apps/yourappname" which will open the App Store on the device
3. The "Leave me alone" button sets the cookie to false and closes the modal

The other option I've played with but found a little clunky was to do the following in Javascript:

setTimeout(function() {
  window.location = "http://itunes.com/apps/yourappname";
}, 25);

// If "custom-uri://" is registered the app will launch immediately and your
// timer won't fire. If it's not set, you'll get an ugly "Cannot Open Page"
// dialogue prior to the App Store application launching
window.location = "custom-uri://";

Ios – How to link to apps on the app store

Edited on 2016-02-02

Starting from iOS 6 SKStoreProductViewController class was introduced. You can link an app without leaving your app. Code snippet in Swift 3.x/2.x and Objective-C is here.

A SKStoreProductViewController object presents a store that allows the user to purchase other media from the App Store. For example, your app might display the store to allow the user to purchase another app.

From News and Announcement For Apple Developers.

Drive Customers Directly to Your App on the App Store with iTunes Links With iTunes links you can provide your customers with an easy way to access your apps on the App Store directly from your website or marketing campaigns. Creating an iTunes link is simple and can be made to direct customers to either a single app, all your apps, or to a specific app with your company name specified.

To send customers to a specific application: http://itunes.com/apps/appname

To send customers to a list of apps you have on the App Store: http://itunes.com/apps/developername

To send customers to a specific app with your company name included in the URL: http://itunes.com/apps/developername/appname

Additional notes:

You can replace http:// with itms:// or itms-apps:// to avoid redirects.

Please note that itms:// will send the user to the iTunes store and itms-apps:// with send them to the App Store!

For info on naming, see Apple QA1633:

https://developer.apple.com/library/content/qa/qa1633/_index.html.

Edit (as of January 2015):

itunes.com/apps links should be updated to appstore.com/apps. See QA1633 above, which has been updated. A new QA1629 suggests these steps and code for launching the store from an app:

Launch iTunes on your computer.
Search for the item you want to link to.
Right-click or control-click on the item's name in iTunes, then choose "Copy iTunes Store URL" from the pop-up menu.
In your application, create an NSURL object with the copied iTunes URL, then pass this object to UIApplication' s openURL: method to open your item in the App Store.

Sample code:

NSString *iTunesLink = @"itms://itunes.apple.com/app/apple-store/id375380948?mt=8";
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:iTunesLink]];

iOS10+:

 [[UIApplication sharedApplication] openURL:[NSURL URLWithString:iTunesLink] options:@{} completionHandler:nil];

Swift 4.2

   let urlStr = "itms-apps://itunes.apple.com/app/apple-store/id375380948?mt=8"
    if #available(iOS 10.0, *) {
        UIApplication.shared.open(URL(string: urlStr)!, options: [:], completionHandler: nil)
        
    } else {
        UIApplication.shared.openURL(URL(string: urlStr)!)
    }

You cannot install these apps on the simulator, you are going to have to test on the device instead.
