Create a method in app.xaml.cs as mentioned above.
1. In platform specific ios project, right click Components> Get Components and install Rivets component.
2. Override OpenUrl method in AppDelegate.cs
3. Save instance of App object created in FinishedLaunching() as a private variable (_app). In OpenUrl use the following code to retrive values from url.
Example code:
// url is NSUrl param which is passed to OpenUrl
var rurl = new Rivets.AppLinkUrl(url.ToString()):
var page ="";
if (rurl.InputQueryParameters.ContainsKey("page"))
page= rurl.InputQueryParameters["page"];
_app.ConfigureParams(/* params*/);
return true;
4. Open info.plist and go to Advanced tab. Configure a Url Type with required Identifier a UrlScheme. This will allow app to recognize different urls schemes.
5. You can test application by running in simulator and open the url with configured scheme in safari.
