namespace Mobile.iOS
{
    public class PickerDataModel : UIPickerViewModel
    {
        public event EventHandler<EventArgs> ValueChanged;

        public List<string> Items
        {
            get { return this._items;} 
            set { this._items = value;}
        }
        List<string> _items = new List<string>();

        public string SelectedItem
        {
            get { return this._items[this._selectedIndex]; }
        }
        protected int _selectedIndex = 0;

        public PickerDataModel()
        {   
        }

        public override int GetRowsInComponent (UIPickerView picker, int component)
        {
            return this._items.Count;
        }

        public override string GetTitle (UIPickerView picker, int row, int component)
        {
            return this._items[row];
        }

        public override int GetComponentCount (UIPickerView picker)
        {
            return 1;
        }

        public override void Selected (UIPickerView picker, int row, int component)
        {

            if (this.ValueChanged != null)
            {
                this.ValueChanged (this, new EventArgs());
            }
        }
    }

在ActionSheet ChildagePicker中公开您的agePickerDataModel并将其公开

我也会让你的UIButton doneButton在ActionSheet ChildagePicker中公开

    public UIButton doneButton = UIButton.FromType (UIButtonType.RoundedRect);

注释掉ActionSheetChildAgePicker中的按钮事件，以便我们可以在视图控制器中处理它

    doneButton.SetTitleColor(MonoTouch.UIKit.UIColor.White, UIControlState.Normal);
    doneButton.SetTitle ("done", UIControlState.Normal);
    //doneButton.TouchUpInside += (s, e) => { actionSheet.DismissWithClickedButtonIndex    (0, true); };

然后在视图控制器中，您可以执行以下操作

  actionSheetChildAgePicker.doneButton.TouchUpInside += (s, e) => { 
  string sPickedAge = actionSheetChildAgePicker.agePickerDataModel.SelectedItem;
  actionSheetChildAgePicker.Hide(true);
                    };

    doneButton.SetTitleColor(MonoTouch.UIKit.UIColor.White, UIControlState.Normal);
    doneButton.SetTitle ("done", UIControlState.Normal);
    //doneButton.TouchUpInside += (s, e) => { actionSheet.DismissWithClickedButtonIndex    (0, true); };

  actionSheetChildAgePicker.doneButton.TouchUpInside += (s, e) => { 
  string sPickedAge = actionSheetChildAgePicker.agePickerDataModel.SelectedItem;
  actionSheetChildAgePicker.Hide(true);
                    };
