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);

Valdyr，希望这对你有帮助

CGPoint bottomOffset = CGPointMake(0, [textView contentSize].height - textView.frame.size.height);

if (bottomOffset.y > 0)
 [textView setContentOffset: bottomOffset animated: YES];

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);

如果你不需要动画，这是可行的:

[self.scrollView setContentOffset:CGPointMake(0, CGFLOAT_MAX) animated:NO];

如果contentSize低于边界怎么办?

对于Swift来说，它是:

scrollView.setContentOffset(CGPointMake(0, max(scrollView.contentSize.height - scrollView.bounds.size.height, 0) ), animated: true)

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)
}
