UIWebView - 如何识别“最后一个"webViewDidFinishLoad 消息? [英] UIWebView - How to identify the "last" webViewDidFinishLoad message?

问题描述

webViewDidFinishLoad 消息似乎是在每次页面中的 any 对象被加载时发送的.有没有办法确定所有内容的加载都已完成?

The webViewDidFinishLoad message seems to be sent each time any object in the page has been loaded. Is there a way to determine that all loading of content is done?

推荐答案

有趣，我没想到它会这样工作.虽然我确定还有其他方法可以做到这一点(有没有办法从 webViewDidFinishLoad 消息中提取 URL，以便您可以看到哪个是完成加载的主页?)，但我能想到的主要是使用估计进度来检查页面的进度，并在 100% 完成加载时触发你想做的任何事情，这就是我在我的应用程序中所做的.谷歌iphone webviewestimatedprogress"并点击第一个链接查看我写的关于如何做到这一点的指南.

Interesting, I wouldn't have thought it would work like that. Although I'm sure there are other ways to do it (is there a way to extract the URL from the webViewDidFinishLoad message so that you can see which one is the main page finishing loading?), the main thing I can think of is using the estimatedProgress to check the progress of the page and fire off whatever you want to do when it's 100% finished loading, which is what I do in my app. Google "iphone webview estimatedprogress" and click the first link for a guide I wrote on how to do this.

更新:

请在下面使用 phopkins 的答案而不是我的答案！在您的应用程序中使用私有 API 是个坏主意，您可能会被拒绝，而他的解决方案是正确的.

Please use phopkins' answer below instead of mine! Using private APIs in your apps is a bad idea and you will probably get rejected, and his solution is the right one.
