Handle the http url with my application (if installed)

I would like to handle the url, for example: http://www.something.com/product/3/ as follows:

  • If the application is installed => processes it using the application.
  • Else => handle safari.

Is it possible?

The idea is that I can send this URL by e-mail, and if the recipient has the application installed, the application rises and does something, and if not installed, just open it via safari.

I know about user schemes that work great in an application, but they obviously don't work in safari, because they are not an http protocol.

Yes, you can do it using the URL Schema . First, create your own URL scheme in the Info.plist file

Add a new line by going to the menu and choosing Editor> Add Item. Customize the Types URL element by adding a new element. Expand the URL type key, expand element 0, and add a new URL Schema element. Fill in the "readtext" for item 0 of "URL Schema" and your company identifier for "URL Identifier".

Then parse your URL for a different URL for the same URL pattern to open the application with different screens. Here I showed only a warning, I use it to open your specific page using your link .. And if the application is not installed, it will open in a web browser.

 - (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url { // Display text UIAlertView *alertView; NSString *text = [[url host] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; alertView = [[UIAlertView alloc] initWithTitle:@"Text" message:text delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alertView show]; [alertView release]; return YES; }

application: handleOpenURL: (used for earlier iOS 4.1) application: openURL: sourceApplication: annotation: (used for later iOS 4.1).

1) Create your own URL scheme in your application. Follow the link if you do not know how to create a custom URL scheme: http://www.idev101.com/code/Objective-C/custom_url_schemes.html

2) Then add the following script to the URLs you want to open.

 <script language="javascript" type="text/javascript"> var iOS = (navigator.userAgent.match(/(iPad|iPhone|iPod)/g) ? true : false); var appUrlScheme = "myappscheme://" + document.URL; if (iOS) { window.open(appUrlScheme, "_self"); } </script>

The script is self-evident if it is an iOS device, then it just tries to open the current url with your custom URL scheme, i.e. myappscheme://whateverurl.com'. If you app is installed on the device then iOS is going to launch your app and pass this URL to myappscheme://whateverurl.com'. If you app is installed on the device then iOS is going to launch your app and pass this URL to handleOpenURL function, otherwise mobile safari will silently ignore window.open`, and your web page will load as usual:

3) Add the handleOpenURL callback method to AppDelegate to handle the url:

 - (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url { NSLog(@"url: %@", url); NSLog(@"query string: %@", [url query]); NSLog(@"host: %@", [url host]); NSLog(@"url path: %@", [url path]); //REDIRECT USER TO A VIEW CONTROLLER return YES; }

No, It is Immpossible. However, you can include both links in the mail:
