UITextView - 禁用垂直滚动 [英] UITextView - disable vertical scrolling

问题描述

如何在UITextView中禁用垂直滚动？我希望它基本上只是水平滚动。

How can I disable vertical scrolling in my UITextView? I want it to basically just scroll horizontally.

推荐答案

在某些情况下，当我试图压制不需要的UITextView滚动时，我发现将以下内容添加到UITextView委托中是有帮助的（这是一个UIScrollView委托方法，当然，UITextView继承自UIScrollView）。这可能适合你。

In some circumstances, when trying to clamp down on unwanted UITextView scrolling I have found it helpful to add something like the following to the UITextView delegate (this is a UIScrollView delegate method but, of course, UITextView inherits from UIScrollView). This might work for you.

- (void)scrollViewDidScroll:(id)scrollView
{
      CGPoint origin = [scrollView contentOffset]; 
      [scrollView setContentOffset:CGPointMake(origin.x, 0.0)];
}

scrollEnabled属性怎么样？将scrollEnabled属性设置为NO会阻止用户滚动（在两个方向上），但有时系统会将 setContentOffset：animated：消息发送到UITextView。 scrollEnabled属性适用于垂直和水平滚动。鉴于您的问题，您可能希望保持原样的scrollEnabled。

What about the scrollEnabled property? Setting the scrollEnabled property to NO stops the user from scrolling (in both directions), but there are occasions where the system sends setContentOffset:animated: messages to a UITextView. The scrollEnabled property applies to both vertical and horizontal scrolling. Given your question, you might want to leave scrollEnabled as is.
