Is there any way to get webview displaying contents froma big html file.

If you want to extract the contents of a UIWebView you can use -stringByEvaluatingJavaScriptFromString .

Example:

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

Hope it helps you.
