UIWebView：什么时候页面真的完成加载？ [英] UIWebView: when did a page really finish loading?

问题描述

我需要知道，当UIWebView完全加载网页时。我的意思是，非常完全，当所有重定向完成并且动态加载的内容准备就绪时。
我尝试注入javascript（查询 document.readyState =='完成'），但这似乎不太可靠。

I need to know, when a web page has completely been loaded by UIWebView. I mean, really completely, when all redirects are done and dynamically loaded content is ready. I tried injecting javascript (querying for document.readyState == 'complete'), but that does not seem to be very reliable.

是否有来自私人api的事件会给我带来结果？

Is there, maybe, an event from the private api that will bring me the result?

推荐答案

<我一直在寻找答案，我从塞巴斯蒂安的问题中得到了这个想法。不知怎的，它对我有用，也许对那些遇到这个问题的人来说。

I have been looking for the answer for this, and I got this idea from Sebastian's question. Somehow it works for me, maybe it will for those who encounter this issue.

我将一个委托设置为UIWebView，在webViewDidFinishLoad中，我检测到webview是否真的完成了通过执行Javascript加载。

I set a delegate to UIWebView and in the webViewDidFinishLoad, I detect if the webview has really finished loading by executing a Javascript.

- (void)webViewDidFinishLoad:(UIWebView *)webView {
    if ([[webView stringByEvaluatingJavaScriptFromString:@"document.readyState"] isEqualToString:@"complete"]) {
        // UIWebView object has fully loaded.
    }
}
