如何阻止 UIWebView 垂直滚动底部“弹跳”?

How to Stop UIWebView from “bouncing” vertically scrolling bottom?

我的问题与this question相同,但有一处不同。当我滚动到顶部刷新我的网站时,我只想停止弹跳到底部滚动的末尾。我该怎么做?

你可以这样试试:

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)
    }   
}

设置你的webview的delegate并设置webview的scrollview的content offset

引用自:

我想你也可以设置滚动视图的反弹

像这样,很简单

-(void)scrollViewDidScroll:(UIScrollView *)scrollView{
    if (scrollView.contentOffset.y > 0) {
        scrollView.bounces = NO;
    }else{
        scrollView.bounces = YES;
    }
}

个人在Xcode7.3中Swift,我在viewDidLoad函数中简单的添加了这个:

UIWebview.scrollView.bounces = false;
