This is the solution that i use

NSUInteger contentHeight = [[webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"document.body.scrollHeight;"]] intValue];

Your webview should have a frame smaller than all possible content size

  • Important to know: I had a lot of issues using this on a certain piece of html/css from a 3rd party. After searching I came to the conclusion that you can get into trouble when the html contains viewport-relative sizing in its CSS. The typical "make 0 pixels high, render webview, query height, set webview height to result" does not work, because if e.g. a font-size is defined as 3.4vh the text will change size when you increase the webview height, invalidating the result of your calculation. – Joris Mans Jan 30 '17 at 13:29

Try This, 

- (void)webViewDidFinishLoad:(UIWebView *)webView {
        CGSize contentSize = webView.scrollView.contentSize;
        NSLog(@"Content Size %@", NSStringFromCGSize(contentSize));
    }
