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)

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)

最简单的解决方案:

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

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)

你可以使用UIScrollView的setContentOffset:animated:函数滚动到内容视图的任何部分。这里有一些代码可以滚动到底部，假设你的scrollView是self.scrollView:

objective - c:

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

迅速:

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

快速执行:

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

使用它:

yourScrollview.scrollToBottom(animated: true)
