Redirect to application if installed, otherwise to App Store

Question

I know it\'s possible to link directly to an app in iOS by registering a custom scheme (e.g. so://) and it\'s also possible to link to the app in the appstore via itunes.

Answer 1

There are few simple steps to achieve this Action

Step 1

Go -> Project (select target) -> info -> URL Types

Create URL Scheme in Xcode Like this

here URL Scheme is myApp (it is better to have all character in lowercase).

Step 2

Setup Delegate if you have plan to receive parameters/Query strings from URL

Here is the code :

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
            options:(NSDictionary *)options {

     NSLog(@"APP : simple action %@",url.scheme);

    if ([url.scheme hasPrefix:@"myapp"]) {

        NSLog(@"APP inside simple %@",url.absoluteString);


        NSURLComponents *urlComponents = [NSURLComponents componentsWithURL:url
                                                    resolvingAgainstBaseURL:NO];
        NSArray *queryItems = urlComponents.queryItems;
        NSString * abc = [self valueForKey:@"abc"
                           fromQueryItems:queryItems];
        NSString * xyz = [self valueForKey:@"xyz"
                           fromQueryItems:queryItems];


        NSLog(@"Sid up = %@", abc);

        NSLog(@"PID up = %@", xyz);

      // you can do anything you want to do here



        return YES;
    }
return NO;
}

End of Xcode side Work.

Step 3

Referring @BananaNeil Code here as i am not Front end guy

(function() {
  var app = {
    launchApp: function() {
      window.location.replace("myApp://share?abc=12&xyz=123");
      this.timer = setTimeout(this.openWebApp, 1000);
    },

    openWebApp: function() {
      window.location.replace("http://itunesstorelink/");
    }
  };

  app.launchApp();
})();

Hope it will HELP you all
