If you look at the docs for a UIWebView, you know your options are limited. You're going to have do it with javascript. Your only weapon is - (NSString *)stringByEvaluatingJavaScriptFromString:(NSString *)script and your ability to load every page as a string (which you can manipulate) before passing it to you UIWebView as a page (using - (void)loadHTMLString:(NSString *)string baseURL:(NSURL *)baseURL).

So... good luck with that. ;)

Ios – Stop UIWebView from “bouncing” vertically

for (id subview in webView.subviews)
  if ([[subview class] isSubclassOfClass: [UIScrollView class]])
    ((UIScrollView *)subview).bounces = NO;

...seems to work fine.

It'll be accepted to App Store as well.

Update: in iOS 5.x+ there's an easier way - UIWebView has scrollView property, so your code can look like this:

webView.scrollView.bounces = NO;

Same goes for WKWebView.

Html – UIWebView loading parsed html string

UIWebView doesn't open target="_blank" links. Certain links don't fire UIWebViewNavigationTypeLinkClicked events. This happens when the link has the target="_blank" attribute.

To work around this problem i used the code below. It injects some javascript after the page load to remove the target attribute from all the links. After using this code i didn;t needed anymore to parse the html source and replace _blank with _self for example.

- (void)webViewDidFinishLoad:(UIWebView *)webView {
        NSString *js = @"\
        var d = document.getElementsByTagName('a');\
        for (var i = 0; i < d.length; i++) {\
            if (d[i].getAttribute('target') == '_blank') {\
                d[i].removeAttribute('target');\
            }\
        }\
        ";

        [webView stringByEvaluatingJavaScriptFromString:js];
}
