Swift版本的易于复制粘贴的接受答案:

let bottomOffset = CGPoint(x: 0, y: scrollView.contentSize.height - scrollView.bounds.size.height)
scrollView.setContentOffset(bottomOffset, animated: true)

扩展UIScrollView添加一个scrollToBottom方法:

extension UIScrollView {
    func scrollToBottom(animated:Bool) {
        let offset = self.contentSize.height - self.visibleSize.height
        if offset > self.contentOffset.y {
            self.setContentOffset(CGPoint(x: 0, y: offset), animated: animated)
        }
    }
}

只是对已有答案的一个改进。

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

它还负责底部的嵌入(以防你在键盘可见时使用它来调整滚动视图)

Swift版本的易于复制粘贴的接受答案:

let bottomOffset = CGPoint(x: 0, y: scrollView.contentSize.height - scrollView.bounds.size.height)
scrollView.setContentOffset(bottomOffset, animated: true)

要滚动到底部，我们必须使用目标视图的最大高度。

import UIKit

extension UIScrollView {

    func scrollToBottomOf(targetView: UIView, animated: Bool) {
        setContentOffset(CGPoint(x:targetView.frame.minX, y:targetView.frame.maxY), animated: animated)
    }
}

//func invocation example 
optionScrollView.scrollToBottomOf(targetView: self.optionsStackView, animated: false)

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);
