如何检测 UIWebView 何时完全完成加载?

问题描述

我正在尝试为 UIWebView 构建一个过滤器，并且我正在努力检测 UIWebView 何时完全完成加载.我使用了以下两种方法

I am trying to build a filter for a UIWebView and I am struggiling to detect when the UIWebView has completely finished loading. I have used the following two methods

– webView:shouldStartLoadWithRequest:navigationType:
– webViewDidFinishLoad:

但问题是当页面有框架和其他内容要加载时，这些将被多次调用.

but the issue is that these will be called multiple times when a page has frames and additional content to load.

我需要知道视图何时已完全加载并且没有更多内容要获取.然后，当内容加载完毕后，我可以对照批准的 URL 列表检查页面的 URL.

What I need is to know when the view has completely loaded and there is no more content to fetch. Then when the content has loaded I can check to URL of the page against a list of approved URLS.

有什么想法吗?

推荐答案

使用UIWebViewDelegate协议方法webViewDidFinishLoad和webView的isLoading属性

 - (void)webViewDidFinishLoad:(UIWebView *)webView
 {
    //Check here if still webview is loding the content
    if (webView.isLoading)
       return;

    //after code when webview finishes
    NSLog(@"Webview loding finished");
 }
