Deepak, You can create a Drop down like control with a help of a UIButton and a UITableView indicating the drop down list. But for sure your application would be rejected by Apple.

Most of the iPhone users would be comfortable using a drop down box in an iPhone app, because people got used to Pickers .

So better go for using UIPicker, which is meant for what you are asking.
