推薦答案
你必須設置 UIScrollView 的 contentSize 屬性.例如，如果你的 UIScrollView 是 320 像素寬(屏幕的寬度)，那么你可以這樣做:
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 只會垂直滾動，因為它已經可以水平顯示所有內容.
The UIScrollView will then only scroll vertically, because it can already display everything horizontally.
