CGFloat yOffset = scrollView.contentOffset.y;

CGFloat height = scrollView.frame.size.height;

CGFloat contentHeight = scrollView.contentSize.height;

CGFloat distance = (contentHeight  - height) - yOffset;

if(distance < 0)
{
    return ;
}

CGPoint offset = scrollView.contentOffset;

offset.y += distance;

[scrollView setContentOffset:offset animated:YES];

Xamarin的。iOS版本的UICollectionView的接受答案，便于复制和粘贴

var bottomOffset = new CGPoint (0, CollectionView.ContentSize.Height - CollectionView.Frame.Size.Height + CollectionView.ContentInset.Bottom);          
CollectionView.SetContentOffset (bottomOffset, false);

滚动到表的最后一项的解决方案

Swift 3:

if self.items.count > 0 {
        self.tableView.scrollToRow(at:  IndexPath.init(row: self.items.count - 1, section: 0), at: UITableViewScrollPosition.bottom, animated: true)
}

Xamarin的。iOS版本的接受答案

var bottomOffset = new CGPoint (0,
     scrollView.ContentSize.Height - scrollView.Frame.Size.Height
     + scrollView.ContentInset.Bottom);

scrollView.SetContentOffset (bottomOffset, false);

最简单的解决方案:

[scrollview scrollRectToVisible:CGRectMake(scrollview.contentSize.width - 1,scrollview.contentSize.height - 1, 1, 1) animated:YES];

使用(可选)footerView和contentInset，解决方案是:

CGPoint bottomOffset = CGPointMake(0, _tableView.contentSize.height - tableView.frame.size.height + _tableView.contentInset.bottom);
if (bottomOffset.y > 0) [_tableView setContentOffset: bottomOffset animated: YES];
