webViewDidFinishLoad：过早开火？ [英] webViewDidFinishLoad: Firing too soon?

问题描述

我正在尝试通过在加载页面时隐藏webView来加载不同的网页。但是，我看到一些图像密集型网站导致webViewDidFinishLoading过快启动，当我在那时显示webView然后一瞬间你得到上一页的视图。关于如何解决这个问题的任何想法？

I'm trying to transition between loading of different web pages by hiding the webView while it is loading a page. However, I'm seeing that some image intensive websites are causing webViewDidFinishLoading to fire too soon and when I show the webView at that point then for a split second you get a view of the previous page. Any ideas on how to resolve this?

推荐答案

如果页面上有Javascript，您可能需要等待它完成。最简单的方法似乎是将一些javascript发送到要执行的页面：

If there's Javascript on the page, you may need to wait for it to finish. The easiest way seems to be to send some javascript to the page to be executed:

-(void) webViewDidFinishLoad:(UIWebView *)webView
{
    NSString *javaScript = @"<script type=\"text/javascript\">function myFunction(){return 1+1;}</script>";
    [webView stringByEvaluatingJavaScriptFromString:javaScript];

  // done here
}

话虽如此，我似乎仍然看到在webViewDidFinishLoad中webview没有完全更新的情况。

Having said that, I seem to still see cases where the webview isn't quite updated within webViewDidFinishLoad.
