How to prevent left-right panning in UIScrollView - iphone

Question

I have built an iPhone app with a page to show the contents of a .txt file in UIScrollView. For some reason my plain txt file causes the Scrollview to allow it to pan slightly to the left and right, I want it to be solid up down scrolling only.
Really need help with this one..
Thanks

Answer 1

CGRectMake(0, 0, 330, (self.view.bounds.size.height - 90))];
Replace 330 with 320. That should do the trick.
Edit: As written in the comments you should prefer self.view.bounds.size.width

Answer 2

The problem likely has to do with this line:
[scrollView setContentSize:[ctView suggestedSizeConstrainedToSize:CGSizeMake(scrollView.bounds.size.width, CGFLOAT_MAX)]];
I don't know what that method does, but it's probably giving you a contentSize with width > 320. Adding the following lines after that would fix it, I think:
if (scrollView.contentSize.width > self.view.bounds.size.width)
[scrollView setContentSize:CGSizeMake(self.view.bounds.size.width,scrollView.contentSize.height)];
