UITableView - scroll to the top

Question

In my table view I have to scroll to the top. But I cannot guarantee that the first object is going to be section 0, row 0. May be that my table view will start from section number 5.

So I get an exception, when I call:

[mainTableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] atScrollPosition:UITableViewScrollPositionTop animated:NO];

Is there another way to scroll to the top of table view?

UITableView is a subclass of UIScrollView, so you can also use:

[mainTableView scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:YES];

Or

[mainTableView setContentOffset:CGPointZero animated:YES];

And in Swift:

mainTableView.setContentOffset(CGPointZero, animated:true)

And in Swift 3 & above:

mainTableView.setContentOffset(.zero, animated: true)

I first tried this with CGRectZero, which is equivalent to CGRectMake(0, 0, 0, 0). This does not work, but oddly the above does. I guess it needs a positive width and height. Thank you. – Keller Jan 14 '13 at 17:57

Note, you will want **animated:NO** if you run this in scrollToRowAtIndexPath: so as to make the table start in the correct position. Hope it helps! – Fattie Jan 27 '14 at 14:25

@hasan83 CGRectMake(0, 0, 0, 0) or CGRectZero isn't a visible rect. I would also say that [mainTableView setContentOffset:CGPointZero animated:YES]; is the prettier expression. – catlan Apr 27 '15 at 05:01

the code sample is too long to post here but basically I am calling a function from viewWillAppear, if some condition is met, I will be scrolling the table view to the top and insert some rows with UIView.animation. The solution from fabb worked but this one did not really scroll – Junchao Gu Jun 17 '15 at 01:47
@JunchaoGu can only suggest to create a stackexchange question with some of the code and maybe a video showing the scroll problem... – catlan Jun 17 '15 at 21:16
`mainTableView.setContentOffset(CGPoint.zero, animated:true)` is more "swifty". – Tim Vermeulen Feb 07 '16 at 23:41
This didn't work for me in a table with multiple sections, each with a header. I had to use tableView.scrollToRow(at: IndexPath(row: 0, section: 0), at: .top, animated: false) – Leon Jul 04 '17 at 14:15
This worked fine for me (Swift 3, XCode 8), but only after I remembered to call `endRefreshing()` before since my UITableView contains an UIRefreshControl. – idrougge Sep 08 '17 at 11:22

Note: This answer isn't valid for iOS 11 and later.

I prefer

[mainTableView setContentOffset:CGPointZero animated:YES];

If you have a top inset on your table view, you have to subtract it:

[mainTableView setContentOffset:CGPointMake(0.0f, -mainTableView.contentInset.top) animated:YES];

This is indeed a clear code, but it does not work when your `tableView` has non-zero `contentInset` from the top. For example: `tableView.contentInset = UIEdgeInsetsMake(5.0f, 0.0f, 250.0f, 0.0f);`. If that is the case, in your code the `tableView` scrolls to `(0.0f, 5.0f)`. – tolgamorf May 08 '13 at 20:36

The solution to my previous comment: `[tableView setContentOffset:CGPointMake(0.0f, -tableView.contentInset.top) animated:YES];` – tolgamorf May 08 '13 at 20:40

Possible Actions:

    self.tableView.scrollToRowAtIndexPath(indexPath, atScrollPosition: .Top, animated: true)
}

func scrollToLastRow() {
    let indexPath = NSIndexPath(forRow: objects.count - 1, inSection: 0)

}

3

func scrollToSelectedRow() {
    let selectedRows = self.tableView.indexPathsForSelectedRows
    if let selectedRow = selectedRows?[0] as? NSIndexPath {
        self.tableView.scrollToRowAtIndexPath(selectedRow, atScrollPosition: .Middle, animated: true)
    }
}

4

func scrollToHeader() {
    self.tableView.scrollRectToVisible(CGRect(x: 0, y: 0, width: 1, height: 1), animated: true)
}

5

func scrollToTop(){
    self.tableView.setContentOffset(CGPointMake(0,  UIApplication.sharedApplication().statusBarFrame.height ), animated: true)
}

Disable Scroll To Top:

func disableScrollsToTopPropertyOnAllSubviewsOf(view: UIView) {
    for subview in view.subviews {
        if let scrollView = subview as? UIScrollView {
            (scrollView as UIScrollView).scrollsToTop = false
        }
        self.disableScrollsToTopPropertyOnAllSubviewsOf(subview as UIView)
    }
}

Modify and use it as per requirement.

Swift 4

  func scrollToFirstRow() {
    let indexPath = IndexPath(row: 0, section: 0)
    self.tableView.scrollToRow(at: indexPath, at: .top, animated: true)
  }

Excellent summary. When you have section headers you'll have to use option4 scrollToHeader. — Vincent, Jan 30 '17 at 08:40

It's better to not use NSIndexPath (empty table), nor assume that top point is CGPointZero (content insets), that's what I use -

[tableView setContentOffset:CGPointMake(0.0f, -tableView.contentInset.top) animated:YES];

Hope this helps.

I have both a plain and a `UITableViewStyleGrouped` (headers scrolls with the contents) and this code works.

DONT USE

 tableView.setContentOffset(.zero, animated: true)

It can sometimes set the offset improperly. For example, in my case, the cell was actually slightly above the view with safe area insets. Not good.

 tableView.scrollToRow(at: IndexPath(row: 0, section: 0), at: .top, animated: true)

On iOS 11, use adjustedContentInset to correctly scroll to top for both cases when the in-call status bar is visible or not.

if (@available(iOS 11.0, *)) {
    [tableView setContentOffset:CGPointMake(0, -tableView.adjustedContentInset.top) animated:YES];
} else {
    [tableView setContentOffset:CGPointMake(0, -tableView.contentInset.top) animated:YES];
}

Swift:

if #available(iOS 11.0, *) {
    tableView.setContentOffset(CGPoint(x: 0, y: -tableView.adjustedContentInset.top), animated: true)
} else {
    tableView.setContentOffset(CGPoint(x: 0, y: -tableView.contentInset.top), animated: true)

I've encountered an issue calling trying some of the methods on an empty tableView. Here's another option for Swift 4 that handles empty tableviews.

extension UITableView {
  func hasRowAtIndexPath(indexPath: IndexPath) -> Bool {
    return indexPath.section < self.numberOfSections && indexPath.row < self.numberOfRows(inSection: indexPath.section)
  }

  func scrollToTop(animated: Bool) {
    let indexPath = IndexPath(row: 0, section: 0)
    if self.hasRowAtIndexPath(indexPath: indexPath) {
      self.scrollToRow(at: indexPath, at: .top, animated: animated)
    }
  }
}

Usage:

// from yourViewController or yourTableViewController
tableView.scrollToTop(animated: true)//or false

This doesn't account for any table header or section header. — rmaddy, Aug 03 '19 at 05:35

For tables that have a contentInset, setting the content offset to CGPointZero will not work. It'll scroll to the content top vs. scrolling to the table top.

Taking content inset into account produces this instead:

[tableView setContentOffset:CGPointMake(0, -tableView.contentInset.top) animated:NO];

Swift 5, iOS 13

I know this question already has a lot of answers but from my experience this method always works:

let last = IndexPath(row: someArray.count - 1, section: 0)
tableView.scrollToRow(at: last, at: .bottom, animated: true)

And this is especially true if you're working with animations (like keyboard) or certain async tasks—the other answers will often scroll to the almost bottom. If for some reason this doesn't get you all the way to the bottom, it's almost certainly because of a competing animation so the workaround is to dispatch this animation to the end of the main queue:

DispatchQueue.main.async {
    let last = IndexPath(row: self.someArray.count - 1, section: 0)
    self.tableView.scrollToRow(at: last, at: .bottom, animated: true)
}

This may seem redundant since you're already on the main queue but it's not because it serializes the animations.

@craft if you have zero rows in your table then you shouldn't be attempting to scroll to the bottom anyway because it's already there. – trndjc Dec 09 '20 at 18:34
@bsod Thanks for the reply. I actually do have a case where it's relevant. I'm scrolling back to the top with section headers but no rows. Also, I think the question is about `top` not `bottom` – craft Dec 09 '20 at 18:45

If you need use Objective-C or you still in love:

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
    [_tableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionTop animated:YES];

Solution with scrollToRow which fixes the problem for empty TableView (needs for search).

import UIKit

extension UITableView {
    
    public func scrollToTop(animated: Bool = false) {
        if numberOfRows(inSection: 0) > 0 {
            scrollToRow(
                at: .init(row: 0, section: 0),
                at: .top,
                animated: animated
            )
        }
    }
    
}

The easiest way that I found to force UITableViewController to scroll-to-the-top under iPhone, iPad and macCatalyst (macOS) is as follows:

prepare to return 0 from [tableView:numberOfRowsInSection:]
call [self.tableView reloadData]
call [self.tableView layoutIfNeeded]
prepare to return the factual row count from [tableView:numberOfRowsInSection:]
call [self.tableView reloadData]

If you i would like move scroll animation in the table, use this code. The scroll move to top with animation in .5 seconds.

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseOut];

[_tableContent scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:YES];

[UIView commitAnimations];

To have a completion when finished, add this extension

// MARK: - UIScrollView

extension UIScrollView {

    /// Animate scroll to top with completion
    ///
    /// - Parameters:
    ///   - duration:   TimeInterval
    ///   - completion: Completion block
    func animateScrollToTop(withDuration duration:  TimeInterval,
                            completion:             @escaping (()->())) {

        UIView.animate(withDuration: duration, animations: { [weak self] in
                self?.setContentOffset(CGPoint.zero, animated: false)
            }, completion: { finish in
                guard finish else {
                    return
                }
                completion()
        })
    }
}

tableView.animateScrollToTop(withDuration: 0.25) { 
    // Finish
}

Here is a simple example of UIScrollView extension that you can use everywhere in your app.

1) First you should create enum with possible scroll directions:

enum ScrollDirection {
    case top, right, bottom, left

    func contentOffsetWith(_ scrollView: UIScrollView) -> CGPoint {
        var contentOffset = CGPoint.zero
        switch self {
            case .top:
                contentOffset = CGPoint(x: 0, y: -scrollView.contentInset.top)
            case .right:
                contentOffset = CGPoint(x: scrollView.contentSize.width - scrollView.bounds.size.width, y: 0)
            case .bottom:
                contentOffset = CGPoint(x: 0, y: scrollView.contentSize.height - scrollView.bounds.size.height)
            case .left:
                contentOffset = CGPoint(x: -scrollView.contentInset.left, y: 0)
            }
        return contentOffset
    }
}

2) Then add extension to UIScrollView:

extension UIScrollView {
    func scrollTo(direction: ScrollDirection, animated: Bool = true) {
        self.setContentOffset(direction.contentOffsetWith(self), animated: animated)
    }
}

3) Thats it! Now you can use it:

myScrollView.scrollTo(.top, animated: false)

This scroll bind to the tableView's content size and it looks more natural than scroll to CGPoint.zero

var cell = tableView.dequeueReusableCellWithIdentifier(“cell”)
if cell == nil {
    cell = UITableViewCell(style: .Value1, reuseIdentifier: “cell”)
}

If you don't want scrolling, you can start and stop the scrolling animation as soon as you start it.

    $('document').ready(function() {
    $("html, body").animate({ scrollTop: 0 }, 500);
    return true;
    });

Also, to animate put values for 'x' and 'y', passing in 0,0 will scroll the page to the top left instantly.

window.scrollTo(x, y);
