使用UIScrollView的setContentOffset:animated:函数滚动到Swift的底部。

let bottomOffset : CGPoint = CGPointMake(0, scrollView.contentSize.height - scrollView.bounds.size.height + scrollView.contentInset.bottom)
scrollView.setContentOffset(bottomOffset, animated: true)

用于水平ScrollView

如果你像我一样有一个水平ScrollView，想要滚动到它的结尾(在我的情况下，它的最右边)，你需要改变接受的答案的某些部分:

objective - c

CGPoint rightOffset = CGPointMake(self.scrollView.contentSize.width - self.scrollView.bounds.size.width + self.scrollView.contentInset.right, 0 );
[self.scrollView setContentOffset:rightOffset animated:YES];

斯威夫特

let rightOffset: CGPoint = CGPoint(x: self.scrollView.contentSize.width - self.scrollView.bounds.size.width + self.scrollView.contentInset.right, y: 0)
self.scrollView.setContentOffset(rightOffset, animated: true)

迅速:

你可以使用这样的扩展:

extension UIScrollView {
    func scrollsToBottom(animated: Bool) {
        let bottomOffset = CGPoint(x: 0, y: contentSize.height - bounds.size.height)
        setContentOffset(bottomOffset, animated: animated)
    }
}

Use:

scrollView.scrollsToBottom(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);

滚动到顶部

- CGPoint topOffset = CGPointMake(0, 0);
- [scrollView setContentOffset:topOffset animated:YES];

滚动到底部

- CGPoint bottomOffset = CGPointMake(0, scrollView.contentSize.height - self.scrollView.bounds.size.height);
 - [scrollView setContentOffset:bottomOffset animated:YES];

如果你不需要动画，这是可行的:

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