Answer 1

Try this:
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
NSString* title = [webView stringByEvaluatingJavaScriptFromString: #"document.title"];
navbar.title = title;
}

If you don't want to display the webview, make it hidden and use above delegate method to get what you want...

A way you could do it is by downloading the HTML content at the target url and parse it, for example using hpple.
Example (not tested):
NSURL *url = [NSURL URLWithString:#"http://..."];
//Only using this for simplicity of the example.
//You should really use an asynchronous method instead (see `NSURLSession`).
NSData *urlData = [NSData dataWithContentsOfURL:url];
//Parse HTML and search for title element
TFHpple *hppleParser = [[TFHpple alloc] initWithHTMLData:data];
TFHppleElement *titleElement = [hppleParser search:#"//title"][0];
NSString titleString = titleElement.text;
