IPhone - conflict between UIScrollView and UIDatePicker with scrolling: one intervenes in the second

Question

I have a UIDatePicker inside a UIScrollView. But UIDatePicker does not respond to scrolling. This is a scroll that scrolls. While reading some online documents, I set the “Delay Content Touches” to NO, now I can see the datepicker launching a small scroll, but still there is a scrollview that takes the final word. I have a place on the screen where the user can tap to scroll the view. So, how can I separate the two kinds of scrolls and make the datepicker scroll in the usual way?

thanks for the help

    if ([view isKindOfClass:[UIDatePicker class]] || [@"UIPickerTable" isEqualToString:[[view class] description]] ) {
        //|| [view isKindOfClass:[UIPicker class]]
        return YES;
    }
    return [super touchesShouldBegin:touches withEvent:event inContentView:view];
}

- (BOOL)touchesShouldCancelInContentView:(UIView *)view {
    if ([view isKindOfClass:[UIDatePicker class]] || [@"UIPickerTable" isEqualToString:[[view class] description]] ) {
        return NO;
    }
