As @nate mentioned above, you can invoke Javascript in a webview:

UIWebView* webView = [[UIWebView alloc] initWithFrame:CGRectZero];
NSString* secretAgent = [webView stringByEvaluatingJavaScriptFromString:@"navigator.userAgent"];

But invoking new Javascript is a bit hacky and creating a zero-size webView is gratuitous, since you already have a webView you're dealing with.

Alternatively you can simply use native methods on your given webView:

NSString* ua = [webView.request valueForHTTPHeaderField:@"User-Agent"];
NSLog(@"User-Agent = %@", ua);

I just ran into a similar issue and needed to make the user agent sent by an NSURLConnection match the one sent by a UIWebView. My solution was to create a UIWebView and then just use javascript to pull out the user agent.

UIWebView* webView = [[UIWebView alloc] initWithFrame:CGRectZero];
NSString* secretAgent = [webView stringByEvaluatingJavaScriptFromString:@"navigator.userAgent"];
