How to disable horizontal scrolling of UIScrollView?

Question

I have a UIView like iPhone\'s Springboard. I have created it using a UIScrollView and UIButtons. I want to disable horizontal scrolli

Answer 1

Disable horizontal scrolling by overriding contentOffset property in subclass.

override var contentOffset: CGPoint {
  get {
    return super.contentOffset
  }
  set {
    super.contentOffset = CGPoint(x: 0, y: newValue.y)
  }
}

Answer 2

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 3

In my case, with Swift 4.2 you can use:

Disable vertical scroll:

func scrollViewDidScroll(_ scrollView: UIScrollView) {
    scrollView.contentOffset.y = 0.0
}

Disable horizontal scroll:

func scrollViewDidScroll(_ scrollView: UIScrollView) {
    scrollView.contentOffset.x = 0.0
}

Answer 4

I had the tableview contentInset set in viewDidLoad (as below) that what causing the horizontal scrolling

self.tableView.contentInset = UIEdgeInsetsMake(0, 30, 0, 0);

Check if there are any tableview contentInset set for different reasons and disable it

Answer 5

Try This:

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

Answer 6

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.
