Iphone drop down list

Use UIPickerView to select from a list of items. If your list contains a large number of items, UITableView would probably be a better choice.

I recommend using UIActionSheet for this. If you keep adding many items to the actionsheet it turns into a uitable. For me it's the ideal alternative.
