我使用一个特定的选择器设置来模仿Xamarin.iOS中下拉列表的操作。代码为：

public void ConfigureSelectPicker(UITextField pickerTextField, List<string> theData)
    {
        PickerViewModel MyModel = new PickerViewModel();
        MyModel._pickerSource = theData;
        var picker = new UIPickerView
        {
            Model = MyModel,
            ShowSelectionIndicator = true,
            TintColor = UIColor.Blue
        };
        var screenWidth = UIScreen.MainScreen.Bounds.Width;
        var pickerToolBar = new UIToolbar(new RectangleF(0, 0, (float)screenWidth, 44)) { BarStyle = UIBarStyle.Default, Translucent = true };
        var flexibleSpaceButton = new UIBarButtonItem(UIBarButtonSystemItem.FlexibleSpace);
        var doneButton = new UIBarButtonItem(UIBarButtonSystemItem.Done, (sender, e) => pickerTextField.ResignFirstResponder());
        doneButton.Clicked += (object sender, EventArgs e) =>
        {
            pickerTextField.Text = MyModel.SelectedItem;
        };
        pickerToolBar.SetItems(new[] { flexibleSpaceButton, doneButton }, false);
        pickerTextField.InputView = picker;
        pickerTextField.InputAccessoryView = pickerToolBar;
    }

字符串
theData列表包含在选择器中被截断的字符串。有没有一种方法可以改变字体大小，使他们适合也文本颜色？
