fading background while UIWebview has focus

Question

Is it possible to fade the background of an app (a lightbox type effect) when a UIWebView has the focus, keeping the UIWebView sharp?

Answer 1

Add another transparent view (to achieve the fading effect) in the superview of the webview:

[self.view addSubview:transparentView];

After that, bring the webview to the front.

[self.view bringSubviewToFront:self.webView];
