'How to open Facebook / Twitter app from my iOS app in Xamarin?

I'm developing an iOS app with Xamarin, in C#.

I have a "contact" UIViewController, with some buttons, including Facebook and Twitter.

I need to open the Facebook and Twitter App with a specific Facebook Page and Twitter profile from my app.

What is the best way to do this?

Try this :

Device.OpenUri(new Uri("fb://page/page_id"));
Device.OpenUri(new Uri("twitter://user?user_id=userid"));

For page_id right click on page and select view source page and find the page_id for facebook and same as for twitter find the userid

In addition to accepted answer, following are my finding to open links in external applications.
To open link in browser:

Device.OpenUri(new Uri("http://example.in/index.html"));

To open group in facebook:

Device.OpenUri(new Uri("fb://group/groupname"));

To open page in facebook:

Device.OpenUri(new Uri("fb://page/page_id"));

To open user in instagram:

Device.OpenUri(new Uri("instagram://user?username=yourUserName"));

To open user in twitter:

Device.OpenUri(new Uri("twitter://userName?user_id=userId"));

To open mail app:

Device.OpenUri(new Uri("mailto:[email protected]"));

You also can use these methods if you are using Xamarin.Forms:

await Launcher.OpenAsync(new Uri("your-link");

await Launcher.TryOpenAsync(new Uri("your-link");

await Launcher.CanOpenAsync(new Uri("your-link");

await Browser.OpenAsync("your-link");

As far as I remember, Browser will try to start the url with it's default application, if installed on the phone when you use:

BrowserLaunchMode.SystemPreferred

For those arriving at this page after me, the Device class has been deprecated. You should now use the Launcher class from the Xamarin.Essentials package.

Here is code that worked for me in 2022, in both iOS and Android. It will open in the Twitter/Facebook apps if they're installed, and in the browser if they're not.

private async void OnTwitterClicked(object sender, EventArgs e)
{
    if(!await Launcher.TryOpenAsync("twitter://user?user_id=762836470772097024"))
    {
        await Browser.OpenAsync("https://twitter.com/RingotanApp");
    }
}

private async void OnFacebookClicked(object sender, EventArgs e)
{
    if (!await Launcher.TryOpenAsync("fb://facewebmodal/f?href=https://www.facebook.com/RingotanApp"))
    {
        await Browser.OpenAsync("https://www.facebook.com/RingotanApp");
    }
}

In iOS, you also need to add the following to Info.plist

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>twitter</string>
    <string>fb</string>
</array>

I used this tool to find my numeric Twitter ID.

Another URI option for Facebook is "fb://page/1761091624175851", where the numeric ID comes from "About --> More Info" on Facebook. However, this URI was janky for me - it would first open the page in the app normally, then switch to the web modal used by facewebmodal. I recommend not using it.
