You can check:

[request.URL isFileURL];

More information here.

Check the URL's scheme. Assuming you have an NSURL* instance called myURL:

if ([[myURL scheme] isEqualToString:@"file"]) {
    NSLog(@"URL %@ is local", myURL);
}

Read Apple's NSURL specification to learn more about accessing different parts of an URL.

Assuming you have a UIWebView* called myWebView, you might call something like:

[[myWebView request] URL]

to get the NSURL* of what the web view currently has loaded. Then you can call that object's scheme as described above.

Check for the file:// protocol in the URL.
