I have created a UIScrollView to select the same effect as the picker in that shaded area. , And the user is able to flip between things in it, but I want to clearly point out what it is that he has chosen as a picker.
You can place a semi-transparent UIView over the scrollview at a certain location. Placing an item in ScrollView will actually require a bit more logic in the situation under the custom view, but it is possible that I have not tried this approach before and it is very simple, but it may be that others There will be some better suggestions.
