如何在uiwebview上设置滚动位置 [英] how to set scroll position on uiwebview

问题描述

我想在我加载的uiwebview上指定行。
我试过

I want to go to specify line on my uiwebview loaded. I tried

[webView stringByEvaluatingJavaScriptFromString：@window.scrollTo（0.0，
100.0）;

[webView stringByEvaluatingJavaScriptFromString:@"window.scrollTo(0.0, 100.0)"];

但它不起作用。我的网页浏览仍然从页面顶部开始。
我只是想知道它，因为我在 UIView 中加载 UIWebview 。
在我的 UIView上查看我的代码：

but its not working. My webview still start with top of the page. I just wonder its because i load the UIWebview inside UIView. Check my code below on my UIView:

- (void)loadView {
    webview = [[WebViewDetail alloc]initWithFrame:[UIScreen mainScreen].applicationFrame];        //initialize a mainView is a UIWebVIew
    webview.managedObjectContext = self.managedObjectContext;
    webview.kitab = self.kitab;
    webview.currentPasal = self.pasal;
    self.title = [NSString stringWithFormat:@"%@ %d", self.kitab, webview.currentPasal];
    self.view=webview;    //make the mainView as the view of this controller    
}

我放了滚动条定位脚本在我的 UIWebView ：

and i put the scroll positioning script on my UIWebView:

- (void)webViewDidFinishLoad:(UIWebView *)webView
{
    int height = [[webView stringByEvaluatingJavaScriptFromString:@"document.body.offsetHeight;"] intValue];

    NSString* javascript = [NSString stringWithFormat:@"window.scrollBy(0, %d);", height];   
    [self stringByEvaluatingJavaScriptFromString:javascript];
}

在这种情况下我想把我的uiwebview放到页面底部加载视图时
但它完全不起作用，任何想法为什么？
我做错了吗？

in this case i want to put my uiwebview go to the bottom of the page when the view is loaded. But its totally not working, any idea why? Am i doing it wrong?

推荐答案

试试

webview.scrollView.contentOffset = CGPointMake(0, 100);
