How to handle custom URL scheme in Xamarin Forms

Question

I have a Xamarin Forms Shell app but I'm focusing on the ios platform at the moment.

Example custom url: myawesomeapp:report?id=22

On iOS, I have added the custom URL scheme 'myawesomeapp' to info.plist. And now clicking on the custom url brings up my app successfully and OpenUrl in AppDelegate gets hit.

But how can I process the id=22 to take me to that particular record?

My app structure is using AppShell. I have an ItemsPage.xaml that lists reports and selecting one will bring up that report on ItemDetailPage.xaml. This is the flow that I want to simulate when following the custom url.

Thanks in advance.

Ideal approach would be to create a method in your App.xaml.cs which will accept the given query and then you can call that method from the OpenUrl.

Here's the example:

App.xaml.cs

public void ParseAndPerformNavigation(string query)
{
   //Do string operation and get the parameter
   //Perform Navigation
}

Your updated OpenUrl should be something like this:

public override bool OpenUrl(UIApplication app, NSUrl url, NSDictionary options)
{
   var App = (App)Xamarin.Forms.Application.Current;
   App.ParseAndPerformNavigation(url.AbsoluteString);
   return false;
}
