title: iOS UIWebView not load url after NSURLConnection
body: <p>Create simple app with iOS 7 SDK but test app on both ios 6.x and 7.x and have same result. 
  There are two ViewControllers – first MainScreen and second WebScreen</p>
  
  <p>If i using NSURLConnection on MainScreen for my url, UIWebView not load content from same site.</p>
  
  <p>In the MainScreen i load json as string from url</p>
  
  <pre><code>NSString *urlAsString = [NSString stringWithFormat:@"https://site.ws/api/index/index?method=get_count_new_orders&amp;login=%@&amp;password=%@", @"login", @"pass"];
  NSURL *url = [[NSURL alloc] initWithString:urlAsString];
  [NSURLConnection sendAsynchronousRequest:[[NSURLRequest alloc] initWithURL:url] queue:[[NSOperationQueue alloc] init] completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
  
          if (error) {
              NSLog(@"error ::: %@", error);
          } else {
  
              NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
  
              NSError *jserror = nil;            
              NSDictionary *JSON = nil;
              JSON = [NSJSONSerialization JSONObjectWithData: [string dataUsingEncoding:NSUTF8StringEncoding] options: NSJSONReadingMutableContainers error: &amp;jserror];
  
          }
  
      }];
  </code></pre>
  
  <p>On the second screen i try load page from same site:</p>
  
  <pre><code>NSString *stringUrl = [NSString stringWithFormat:@"https://reserva.ws/?lang=en"];
  [self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:stringUrl]]];
  </code></pre>
  
  <p>and UIWebView load empty page.</p>
  
  <p>But, if i comment [NSURLConnection sendAsynchronousRequest... on first screen, webview work fine.</p>
