How to disable horizontal scrolling of UIScrollVie

Question

I have a UIView like iPhone's Springboard. I have created it using a UIScrollView and UIButtons. I want to disable horizontal scrolling on said scrollview. I want only vertical scrolling. How do i accomplish this?

Answer 1

Use this single line.

self.automaticallyAdjustsScrollViewInsets = NO;

Answer 2

I struggled with this for some time trying unsuccessfully the various suggestions in this and other threads.

However, in another thread (not sure where) someone suggested that using a negative constraint on the UIScrollView worked for him.

So I tried various combinations of constraints with inconsistent results. What eventually worked for me was to add leading and trailing constraints of -32 to the scrollview and add an (invisible) textview with a width of 320 (and centered).

Answer 3

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];

The UIScrollView will then only scroll vertically, because it can already display everything horizontally.

Answer 4

Try This:

CGSize scrollSize = CGSizeMake([UIScreen mainScreen].bounds.size.width, scrollHeight);
[scrollView setContentSize: scrollSize];

Answer 5

In my case the width of the contentView was greater than the width of UIScrollView and that was the reason for unwanted horizontal scrolling. I solved it by setting the width of contentView equal to width of UIScrollView.

Hope it helps someone
