推荐答案

你必须设置 contentSize UIScrollView 的属性。例如，如果您的 UIScrollView 是320像素宽（屏幕宽度），那么您可以这样做：

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.
