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

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

UPDATED   After  EranMarom pointed out on his comment   You can stop horizontal scrolling or vertical scrolling in the ScrollViewDelegate Method  Here it is how   Stops Horizontal Scrolling   If you want to scroll horizontally  then you need to increase the contentOffset x  Preventing that stops the scrollview scroll in horizontal direction   -  void scrollViewDidScroll  UIScrollView   sender       sender contentOffset x   0 0     Stops Vertical Scrolling   If you want to scroll vertically  then you need to increase the contentOffset y  Preventing that stops the scrollview scroll in vertical direction   -  void scrollViewDidScroll  UIScrollView   sender       sender contentOffset y   0 0     Above code prevents the changes in x and y of a scrollview contentOffset and it leads to stop the scrolling in scrollViewDidScroll  method

Swift solution   Create two outlets  one for your view and one for your scroll view    IBOutlet weak var myView  UIView   IBOutlet weak var scrollView  UIScrollView    Then in your viewDidLayoutSubviews you can add the following code   let scrollSize   CGSize width  myView frame size width                           height  myView frame size height  scrollView contentSize   scrollSize   What we ve done is collected the height and width of the view and set the scrollViews content size to match it  This will stop your scrollview from scrolling horizontally      More Thoughts   CGSizeMake takes a width  amp  height using CGFloats  You may need to use your UIScrollViews existing height for the second parameter  Which would look like this   let scrollSize   CGSize width  myView frame size width                           height  scrollView contentSize height
