iPhone UIWebview — Saving an image already downloaded

Question

I have an iPhone app with an embedded UIWebview (Safari) control. I\'d like to be able to store the images from certain webpages locally.

Can I programmatically acces

Answer 1

I do not know if you can access the preloaded images from Safari's cache...

However you can easily find the image URLs without parsing HTML, by running a bit of javascript instead:

NSString *script = @"var n = document.images.length; var names = [];"
                    "for (var i = 0; i < n; i++) {"
                    "     names.push(document.images[i].src);"
                    "} String(names);";
NSString *urls = [webView stringByEvaluatingJavaScriptFromString:script];
// urls contains a comma-separated list of the image URLs.
