[MonoTouch] Button TitleText Not showing up

[bryan costanich]

hey all, i am creating a custom UIActionSheet and i'm adding some stuff to it, so far everything is working, except i set my button's TitleLabel.Text, and the button shows up blank. i've tried changing the colors thinking that it was just a color issue, but that hasn't helped. this is my code, am i doing something wrong?:

        //========================================================================
        protected void ShowActionSheetPicker (string actionSheetTitle)
        {
            //---- declare vars
            UIActionSheet actionSheet;

            UIButton btnDone = UIButton.FromType (UIButtonType.RoundedRect);
            UILabel lblActionSheetTitle = new UILabel ();
            UIFont titleFont = UIFont.FromName ("helvetica", 18);
            float actionSheetWidth = this.View.Frame.Width;
            float actionSheetHeight = 310;
            float btnDoneWidth = 50;
            float btnDoneHeight = 35;

            //---- setup our picker view
            // it autosizes, so empty is fine
            this._lstPicker = new UIPickerView (RectangleF.Empty);
            this._lstPicker.ShowSelectionIndicator = true;
            this._lstPicker.Model = this._peopleModel;

            //---- configure our label
            lblActionSheetTitle.Text = actionSheetTitle;
            lblActionSheetTitle.BackgroundColor = UIColor.Clear;
            lblActionSheetTitle.TextColor = UIColor.White;
            lblActionSheetTitle.Font = titleFont;

            //---- create + configure the action sheet
            actionSheet = new UIActionSheet ("", null, "Cancel", null) { Style = UIActionSheetStyle.Default };
            actionSheet.Style = UIActionSheetStyle.BlackTranslucent;
            actionSheet.Clicked += delegate(object sender, UIButtonEventArgs args) { Console.WriteLine ("Clicked on item {0}", args.ButtonIndex); };

            //---- configure our "done" button
            btnDone.TitleLabel.Text = "done";
            //btnDone.BackgroundColor = UIColor.DarkGray;
            //btnDone.TitleLabel.BackgroundColor = UIColor.DarkGray;
            //btnDone.TitleLabel.TextColor = UIColor.White;
            //btnDone.TitleLabel.TextColor = UIColor.Black;

            //---- show the action sheet and add the controls to it
            actionSheet.ShowInView (this.View);
            actionSheet.AddSubview (this._lstPicker);
            actionSheet.AddSubview (lblActionSheetTitle);
            actionSheet.AddSubview (btnDone);

            //---- resize the action sheet to fit our other stuff
            actionSheet.Frame = new System.Drawing.RectangleF (0f, UIScreen.MainScreen.Bounds.Height - actionSheetHeight, actionSheetWidth, actionSheetHeight);

            //---- move our picker to be at the bottom of the actionsheet
            float pickerY = actionSheetHeight - this._lstPicker.Frame.Height;
            this._lstPicker.Frame = new RectangleF (this._lstPicker.Frame.X, pickerY, this._lstPicker.Frame.Width, this._lstPicker.Frame.Height);

            //---- move our label to the top of the action sheet
            lblActionSheetTitle.Frame = new RectangleF (10, 5, this.View.Frame.Width - 100, 35);

            //---- move our button
            btnDone.Frame = new RectangleF (actionSheetWidth - btnDoneWidth - 20, 5, btnDoneWidth, btnDoneHeight);

            //actionSheet.SendSubviewToBack (this._lstPicker);
        }
        //========================================================================
