  I am using ARC</p>
  
  <p><img src="https://i.stack.imgur.com/64t2r.png" alt="here is the image for the same"> 
  <br>and when dismissing the <code>UIWebViewController</code>[<code>Viewcontroller</code> which contains UIWebView], it doesnt releases the memory.
  Can any body help me how to solve this memory issues as well as please also provide  me pointers of memory bestpractices in <code>ARC</code></p>
  
  <p>For loading the webpage :-</p>
  
  <pre><code>NSURL *nsurl=[NSURL URLWithString:self.url];
      NSURLRequest *nsrequest=[NSURLRequest requestWithURL:nsurl];
      [webview loadRequest:nsrequest];
  </code></pre>
  
  <p>FOr Dismissing the Viewcontroller:-</p>
  
  <pre><code>[self dismissViewControllerAnimated:YES completion:^{
      webview.delegate=nil;
      webview=nil;
  }];
  </code></pre>
