问题
Im using a navigation controller and a normal view. In the view I'd like a UIPickerView with custom values in it. It would have one column with about 15 values in it. And I want the ability to add an action to each value.
Is there any way I can do this using Xcode? I can't seem to find the corrent help.
Cheers.

You need to look at the documentation for UIPickerViewDelegate.
In order to have an action for each value you will implement pickerView:didSelectRow:inComponent: and have a different action based on which row was selected.
For the contents of the rows you can implement pickerView:titleForRow:forComponent: if your contents are simple text.
If you want custom drawn contents you can provide a custom view for each row with the pickerView:viewForRow:forComponent:reusingView: method.
See the UICatalog example that is available in the iPhone Developer examples.
