Reading HTML content from a UIWebView

Is it possible to read the raw HTML content of a web page that has been loaded into a UIWebView?

If not, is there another way to pull raw HTML content from a web page in the iPhone SDK (such as an equivalent of the .NET WebClient::openRead)?

if you want to extract the contents of an already-loaded UIWebView, -stringByEvaluatingJavaScriptFromString. For example:

NSString  *html = [webView stringByEvaluatingJavaScriptFromString: @"document.body.innerHTML"];

To get the whole HTML raw data (with <head> and <body>):

NSString *html = [webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.outerHTML"];

I use a swift extension like this:

extension UIWebView {
    var htmlContent:String? {
        return self.stringByEvaluatingJavaScript(from: "document.documentElement.outerHTML")
    }

}

To read:-

NSString *html = [myWebView stringByEvaluatingJavaScriptFromString: @"document.getElementById('your div id').textContent"];
NSLog(html);

To modify:-

html = [myWebView stringByEvaluatingJavaScriptFromString: @"document.getElementById('your div id').textContent=''"];
