iOS How i can create custom UIPickerView

[pashik]

Hi.
how i can create class from UIPickerView with custom delegate?
So there will be 2 separate delegates for 2 different UIPickerViews which can be created in UIViewController.

So if i use UIViewController: UIViewController <UIPickerViewDelegate, MyCustomPickerViewDelegate>

there will be 2 separate methods, 1 from normal UIPickerDelegate:

-(void)pickerViewUIPickerView *)pickerView didSelectRowNSInteger) row inComponentNSInteger)component;

and another with my custom class

?????? - don't know how to do it

thanx in advance
