I found a very simple solution; by setting UIpickerview background as clear color then add a new UIView (MiddleRowBackground named) at both center horizontal and vertical position of UIPickerView. set height of MiddleRowBackground the same the Cell's height of UIPickerView which defined in optional func pickerView(_ pickerView: UIPickerView, rowHeightForComponent component: Int) -> CGFloat. Width is the same with UIPickerView.
