I'm using a UIPickerView, and it has the first value chosen by default. When the user doesn't move the UIPickerView from this initial selection, however, the value selected comes back as NSNull. How can I make it so either:

  1. The first value is recognized whether the user changes the selection or not.
  2. The UIPickerView contains a blank value that I can check for in the first spot.

You can use 

[_picker selectedRowInComponent:0]

nil means no one move the picker (you can make the first item blank or sth like "--" )
