回答by Guillaume
If you want the source code of an already loaded webview, you can get it like this:
如果你想要一个已经加载的 webview 的源代码，你可以这样得到：
NSString *yourHTMLSourceCodeString = [webView stringByEvaluatingJavaScriptFromString:@"document.body.innerHTML"];
Update:method above works most of the time. But I recently was in a situation where I needed all the code source, not just the body.
更新：上述方法大部分时间都有效。但我最近遇到了一种情况，我需要所有的代码源，而不仅仅是正文。
Here is a better way:
这是一个更好的方法：
NSString *yourHTMLSourceCodeString = [webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.outerHTML"];
(It won't reload the webview).
（它不会重新加载网络视图）。

I am not sure that what exactly you need..........but as per your last comment you will get that html data from google like this...
我不确定你到底需要什么..........但是根据你的最后一条评论，你会像这样从谷歌获得 html 数据......
NSData *companyData = [NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://www.google.com"]];
NSString *responseString = [[NSString alloc] initWithData:companyData encoding:NSUTF8StringEncoding];
self.yourTextView.text = responseString; // response string contains that data
[companyData release];
Good Luck!
祝你好运！
