I have a UIPickerView in my viewController. I can get the value of the row number of the selected value in the picker from the delegate method

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component

But in my case, I need to get the row number of the selected component as soon as the view appears. Is there a way to get the row number/trigger the delegate method as soon as the view appears.
