Hi folks. I'm looking for a little bit of coding help. Basically, I'm trying
to add a UIDatePicker to a UIPopOever and then display the popover. I've
started with this SO example. Unfortunately, I'm getting the dreaded null
reference exception. Unfortunately, I'm not getting an error. I've been
trying this with different options for a few hours with no success. Any ideas
are appreciated.
Code:
uid = new UIDatePicker();
uid.Mode = UIDatePickerMode.Date; uid.Date =
dateSelected; uid.MinimumDate = DateTime.Now;
uid.Frame = new RectangleF(0, 44, 320, 216);
UIViewController popoverContent = new UIViewController();
UIView popoverView = new UIView();
popoverView.BackgroundColor = UIColor.Black;
popoverView.AddSubview(uid); popoverContent.View =
popoverView; UIPopoverController popovercontroller = new
UIPopoverController(popoverContent);
popovercontroller.PopoverContentSize = new SizeF(320,264);
popovercontroller.PresentFromRect(this.btnDateSelected.Frame, this.View,
UIPopoverArrowDirection.Any, true);
Exception:
System.NullReferenceException: Object reference not set to an instance of an
object at

I put this out at http://pastebin.com/vFMKyYrG if it is of any help.
