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?

推荐答案

你必须设置 UIScrollView 的 contentSize 属性.例如，如果你的 UIScrollView 是 320 像素宽(屏幕的宽度)，那么你可以这样做:

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];

UIScrollView 只会垂直滚动，因为它已经可以水平显示所有内容.

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