Disabling vertical scrolling in UIScrollView

Question

There is an option in IB to uncheck vertical scrolling on a scrollview, but it doesnt seem to work.

How can the scrollview be set to only scroll horizontally, and no

Answer 1

- (void)scrollViewDidScroll:(UIScrollView *)aScrollView
{
    [aScrollView setContentOffset: CGPointMake(aScrollView.contentOffset.x,0)];

}

you must have confirmed to UIScrollViewDelegate

aScrollView.delegate = self;
