Get UIScrollView to scroll to the top

Question

How do I make a UIScrollView scroll to the top?

Answer 1

iOS 11 and above

Try to play around with the new adjustedContentInset (It should even work with prefersLargeTitles, safe area etc.)

For example (scroll to the top):

var offset = CGPoint(
    x: -scrollView.contentInset.left, 
    y: -scrollView.contentInset.top)

if #available(iOS 11.0, *) {
    offset = CGPoint(
        x: -scrollView.adjustedContentInset.left, 
        y: -scrollView.adjustedContentInset.top)    
}

scrollView.setContentOffset(offset, animated: true)

Answer 2

Swift 3.0.1 version of rob mayoff's answer :

self.scrollView.setContentOffset(
CGPoint(x: 0,y: -self.scrollView.contentInset.top),
animated: true)

Answer 3

UPDATE FOR iOS 7

[self.scrollView setContentOffset:
    CGPointMake(0, -self.scrollView.contentInset.top) animated:YES];

ORIGINAL

[self.scrollView setContentOffset:CGPointZero animated:YES];

or if you want to preserve the horizontal scroll position and just reset the vertical position:

[self.scrollView setContentOffset:CGPointMake(self.scrollView.contentOffset.x, 0)
    animated:YES];

Answer 4

In SWIFT 5 Just set content Offset to zero

scrollView.setContentOffset(CGPoint.zero, animated: true)

Answer 5

For Swift 4

scrollView.setContentOffset(.zero, animated: true)

Answer 6

It's very common when your navigation bar overlaps the small portion of the scrollView content and it looks like content starts not from the top. For fixing it I did 2 things:

• Size Inspector - Scroll View - Content Insets --> Change from Automatic to Never.
• Size Inspector - Constraints- "Align Top to" (Top Alignment Constraints)- Second item --> Change from Superview.Top to Safe Area.Top and the value(constant field) set to 0
