title: Adding a combo box or drop-down list to UIView
body: <p>I need to add a combo box or drop-down list to a UIView. I did not find such an object in the "Library" of the interface builder. How do I add this object to my UIVIEW? Do I have to inherit it from another object (which one?) or do I have to create it from scratch programmatically?
  Please help !!!</p>
