For your UISegmentedControl, you'll need to register target-action methods. For example:

[segmentedControl addTarget:self
                 action:@selector(updatePicker:)
       forControlEvents:UIControlEventValueChanged];

Inside of updatePicker, set a variable that corresponds to whatever you want to show in your picker. Then, to your picker instance (you should only have one instance of this class), send the reloadAllComponents message. This will update the picker by querying the delegate for new data. In your delegate (which can probably all be the same class), you'll want to check the value of the variable you set in updatePicker to determine what data to return to the picker.
