Get UIScrollView to scroll to the top

How do I make a UIScrollView scroll to the top?

Solution 1:

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];

Solution 2:

Here is a Swift extension that makes it easy:

extension UIScrollView {
    func scrollToTop() {
        let desiredOffset = CGPoint(x: 0, y: -contentInset.top)
        setContentOffset(desiredOffset, animated: true)
   }
}

Usage:

myScrollView.scrollToTop()
