title: UIPickerView with NSDictionary
body: <p>I am a .NET programmer and new to Objective C. </p>
  
  <p>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. </p>
  
  <p>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. </p>
  
  <p>Please help. </p>
