iPhone:通过IB添加项目时，UIScrollView不滚动 [英] iPhone: UIScrollView not scrolling when adding item via IB

问题描述

我正在尝试通过IB创建一个非常简单的滚动页面.我得到的是顶部是 UIImageView ，底部是2个 UIImageViews ，中间是 UITextView .我已禁用了 UITextView 中的滚动，因为我不会整个页面上下滚动，包括 UIImageViews .

I'm trying to make a very simple scrolling page via IB. What I've got is a UIImageView at the top and 2 UIImageViews at the bottom, with a UITextView in the middle. I've disabled the scrolling in the UITextView as I won't the whole page to scroll up and down including the UIImageViews.

谁能告诉我为什么 UIScrollView 不能上下滚动?上面的所有项目都是 UIScrollView 通过 IB 的子视图.

Can anyone tell me why the UIScrollView won't scroll up and down? All of the items above are subviews of UIScrollView via IB.

推荐答案

如果 contentSize 大于框架，则只能在 UIScrollView 中滚动.你设置好了吗?

You can only scroll in a UIScrollView if the contentSize is larger than the frame. Have you set this?
