推荐答案

您可以尝试这样:

override func viewDidLoad() {
    super.viewDidLoad()

    webview.scrollView.delegate = self

}

func scrollViewDidScroll(scrollView: UIScrollView) {

    if (scrollView.contentOffset.y >= scrollView.contentSize.height - scrollView.frame.size.height) {
        scrollView.setContentOffset(CGPointMake(scrollView.contentOffset.x, scrollView.contentSize.height - scrollView.frame.size.height), animated: false)
    }   
}

设置您的Web视图的委托并设置Web视图的滚动视图的内容偏移量

Set the delegate of your webview and set the content offset of the webview's scrollview
