Xamarin.forms ios open dialer without alert box - xamarin.forms

Question

I am using Xamarin.Essentials Phone Dialer in my xamarin forms app to make calls. In android when we click call it will directly open dialer. In ios when we click call it will firstly show a alert box that will ask Call or cancel. Is it possible to open the dialer in ios without showing the popup? If it is not possible can we get the alert box cancel or call click event?

Answer 1

Unfortunately, this is not possible in iOS.
From Apple's documentation:
openURL
When a third party application invokes openURL: on a tel://,
facetime://, or facetime-audio:// URL, iOS displays a prompt and
requires user confirmation before dialing.
For security reasons, iOS requires users to confirm they want to perform the call before dialing in.

No, it is by design.

You have to detect the state of phone call by yourself in the iOS project, you can write below codes in the AppDelegate:
CXCallObserver callObserver = new CXCallObserver();
callObserver.SetDelegate(new myDelegate(), DispatchQueue.MainQueue);
And in the delegate, you can check the call state:
public class myDelegate : ICXCallObserverDelegate
{
public IntPtr Handle => throw new NotImplementedException();
public void CallChanged(CXCallObserver callObserver, CXCall call)
{
if (call.Outgoing==true && call.HasConnected ==false)
{
Console.WriteLine("Dialing");
//use Messaging Center to send the state to Xamarin.forms Project.
}
if (call.Outgoing ==false && call.HasConnected == false)
{
Console.WriteLine("disconnect");
//use Messaging Center to send the state to Xamarin.forms Project.
}
//you can use other state to check the state...
//call.OnHold; call.HasEnded;
}
public void Dispose()
{
}
}
