Disabling vertical scrolling in UIScrollView

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 not vertically in the code rather than IB?

since iOS7:

first: the content size width must be equal to the width of your scrollview

second: in your initWithNibName:

self.automaticallyAdjustsScrollViewInsets = NO;

That´s it.

Try setting the contentSize's height to the scrollView's height. Then the vertical scroll should be disabled because there would be nothing to scroll vertically.

scrollView.contentSize = CGSizeMake(scrollView.contentSize.width,scrollView.frame.size.height);
