You wont see the picker until you set the data source and the delegate correctly. However you provide no code in your question which makes it hard to resolve your problem.

OK, Xcode 4.5 -

Add a pickerview to a view and a button. If AutoLayout is turned on, it will display both... If Autolayout is off - it will only display the button...

UNTIL - you connect up the DataSource and Delegate CORRECTLY...

So, you can check the Autolayout button to see if it appears, then you know that your datasource and delegate are not set up correctly

You have to implement the protocols in the .h file Then there are about 4 methods you have to code - Number of components Number of Rows Title For Row, and a few others to select rows.
