In Xamarin and C#:

var alert = new UIAlertView ("Your title", "Your description", null, "Cancel", new [] {"OK"});
alert.AlertViewStyle = UIAlertViewStyle.PlainTextInput;
alert.Clicked += (s, b) => {
    var title = alert.ButtonTitle(b.ButtonIndex);
    if (title == "OK") {
        var text = alert.GetTextField(0).Text;
        ...
    }
};

alert.Show();
