Entry element for mm:ss with MonoTouch.Dialog?

I am giving a try to MonoTouch and MonoTouch.Dialog and was wondering what would be the best way to create a Time entry element for minutes and seconds only. The TimeElement only seems to support hours and minutes.

I am very new to the whole framework, so I am wondering if there a way to create a text entry element with sort of a "##:##" mask and use a numeric keypad to populate the minutes and seconds?

A cooler option would be to use a section that would take the user to a view with two "Picker Views" (rotating wheels) for minutes and seconds, but I am not there yet.

Thanks in advance

MonoTouch.Dialog's source code is available on Github (https://github.com/migueldeicaza/MonoTouch.Dialog/tree/master/MonoTouch.Dialog).

There, have a look at the implementation of the DateElement (https://github.com/migueldeicaza/MonoTouch.Dialog/blob/master/MonoTouch.Dialog/Elements.cs#L1827)

To get you a TimeElementMinutesSeconds, all you have to do is (untested) abuse the count down mode. It will offer hours and minutes, but you can just interpret them as minutes and seconds:

public class TimeElementMinutesSeconds : DateTimeElement {
        public TimeElementMinutesSeconds (string caption, DateTime date) : base (caption, date)
        {
        }

        public override string FormatDate (DateTime dt)
        {
            DateTime dtLocal = GetDateWithKind (dt).ToLocalTime ();
return string.Format("{0:##}:{1:##}"dtLocal.Hours, dtLocal.Minutes);
        }

        public override UIDatePicker CreatePicker ()
        {
            var picker = base.CreatePicker ();
            picker.Mode = UIDatePickerMode.CountDownTimer;
            return picker;
        }
    }

If that doesn't get you near enough, you can create your own picker and return that instead.
