如何获取 UIWebView
的 HTML
源代码并将其存储在 NSString
中?
How can I get the HTML
source code of a UIWebView
and store it in NSString
?
如果你想要一个已经加载好的webview的源代码,你可以这样获取:
If you want the source code of an already loaded webview, you can get it like this:
NSString *yourHTMLSourceCodeString = [webView stringByEvaluatingJavaScriptFromString:@"document.body.innerHTML"];
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,我需要所有代码源,而不仅仅是正文.
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.
这里有一个更好的方法:
Here is a better way:
NSString *yourHTMLSourceCodeString = [webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.outerHTML"];
(它不会重新加载 webview).
(It won't reload the webview).
