title: iOS 7 UIWebView clear cache does not work
body: <p>In my project I use UIWebView and after some time I should clear cache. I use this code to do clearing:</p>
  
  <pre><code>[[NSURLCache sharedURLCache] removeAllCachedResponses];
  </code></pre>
  
  <p>But in iOS 7 this code doesn't work (in earlier versions everything is OK). It seems, that cached page still loads. For testing cache I use <a href="http://www.lagado.com/tools/cache-test" rel="nofollow">this page</a>.
  And another issue is when I use cache policy. It doesn't work too:</p>
  
  <pre><code>NSURLRequest *request = [NSURLRequest requestWithURL:
      [NSURL URLWithString:@"http://www.lagado.com/tools/cache-test"] 
      cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:30.0];
  [self.webView loadRequest:request];
  </code></pre>
  
  <p>This code also always uses cached page.</p>
  
  <p>Does anyone have any ideas about this? Thanks for any help!</p>
