This finds the scrollView and scrolls to the top. We search all subviews because more than one subview responds to setContentOffset, but don't bother checking which one.

- (void)methodThatCreatesTheAlertController
{
    // make the alertController here, add actions, and then...

    [self presentViewController:alertController animated:YES completion:^{
        [self scrollToTopOfAlertControllerView:alertController.view];
    }];

}

- (void)scrollToTopOfAlertControllerView:(UIView *)view
{
    for ( UIView *aSubview in view.subviews ) {
        if ( [aSubview respondsToSelector:@selector(setContentOffset:animated:)] ) {
            // _UIInterfaceActionGroupHeaderScrollView
            // _UIInterfaceActionRepresentationsSequenceView <-- this is the one that scrolls
            [((UIScrollView *)aSubview) setContentOffset:CGPointZero animated:YES];
        }
        [self scrollToTopOfAlertControllerView:aSubview]; // recurse
    }
}
