UIPickerView with NSDictionary

Question

I am a .NET programmer and new to Objective C.

I am trying to make a UIPickerView which acts like a .NET dropdownlist. User sees the list of text and selects one and the selected value (which is the ID) is used in code.

I have been browsing for almost half a day trying to figure this out. I could add a regular PickerView with list of strings, picker view with mulitple components and picker view with dependent components none of which seems to answer my query.

Please help.
