ios - How to disable horizontal scrolling of UIScrollView?

Question

I have a UIView like iPhone's Springboard. I have created it using a UIScrollView and UIButtons. I want to disable horizontal scrolling on said scrollview. I want only vertical scrolling. How do I accomplish this?

Answer 1

You have to set the contentSize property of the UIScrollView. For example, if your UIScrollView is 320 pixels wide (the width of the screen), then you could do this:

CGSize scrollableSize = CGSizeMake(320, myScrollableHeight);
[myScrollView setContentSize:scrollableSize];

The UIScrollView will then only scroll vertically, because it can already display everything horizontally.
