Is there a way to get the call status back after a call is made from an app. I am using following to make a call
NSUrl url = new NSUrl("tel://" + phoneStr);
UIApplication.SharedApplication.OpenUrl(url);
It shows a pop up with "Cancel" and "Call" button. If user cancels it stays back in the app, if user clicks call it initiates a call. I would like to get the click action if user made a call or canceled it. Is there a way to get that status
On iOS 10+ We can use CXCallObserver to capture the event when user make a phone call like:
//Make sure both CXCallObserver and ObserverDelegate a strong reference
private CXCallObserver callObserver;
private MyCallObserverDelegate myCallDelegate;
callObserver = new CXCallObserver();
myCallDelegate = new MyCallObserverDelegate();
callObserver.SetDelegate(myCallDelegate, null);
Implement the delegate for CXCallObserver:
public class MyCallObserverDelegate : CXCallObserverDelegate
{
public override void CallChanged(CXCallObserver callObserver, CXCall call)
{
Console.WriteLine(call.Outgoing);
Console.WriteLine(call.HasConnected);
Console.WriteLine(call.OnHold);
Console.WriteLine(call.HasEnded);
}
}
But unfortunately, it will not fire when user click cancel.
After user click the button(cancel or call), the app will fire DidBecomeActiveNotification, so I recommend you create a delay method when DidBecomeActiveNotification fires. Then we can detect which button user clicks:
NSNotificationCenter.DefaultCenter.AddObserver(UIApplication.DidBecomeActiveNotification, async (notification) =>
{
await Task.Delay(500);
detectCalling();
});
In early time we can define a field bool isDialing = false, if CallChanged() fires set it true. At last we can detect the field in detectCalling();.
