this is not good solution but im using NSTimer for updating status of buttons:

- (BOOL)webView:(UIWebView *)_webview shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
    if (!_timer && [request.URL.absoluteString rangeOfString:@"youtube.com"].length != 0) {
        _timer = [NSTimer scheduledTimerWithTimeInterval:0.5
                                                  target:self
                                                selector:@selector(checkNavigationStatus)
                                                userInfo:nil
                                                 repeats:YES];
    }

    return YES;
}

//....
//....
//....

- (void)checkNavigationStatus
{
    // Check if we can go forward or back
    backButton.enabled = self.webView.canGoBack;
    forwardButton.enabled = self.webView.canGoForward;
}
