UITextView - disable vertical scrolling

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

Answer Source

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)];

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.
