The warning and error are two different things.

Error:

The invalid selector on the TouchUpInside can be caused be a few different things, since you did not post code on how you are setting it up, but I would look at if you have any additional actions for the button assigned in the Storyboard, if the button (or its ViewController) is going out of scope, etc..

Warning:

Warning CS0618: 'UIAlertView.UIAlertView(string, string, UIAlertViewDelegate, string, params string[])' is obsolete:

UIAlertView is deprecated in iOS 8, so if you are targeting iOS 9+, you should use UIAlertController

var uiAlert = UIAlertController.Create("Touch2", "TouchUpInside handled", UIAlertControllerStyle.Alert);
uiAlert.AddAction(UIAlertAction.Create("OK", UIAlertActionStyle.Default, (alertAction) => { 
    alertAction.Dispose(); 
    uiAlert.Dispose(); 
}));
await PresentViewControllerAsync(uiAlert, true);
