title: Xcode analyze says 'Potential leak of an object'
body: <p>I'm a beginner and i found this warning here after running 'Analyze' on Xcode:</p>
  
  <pre><code>IphoneFeatureImageDetailViewController *img = [[IphoneFeatureImageDetailViewController alloc] initWithNibName:@"IphoneFeatureImageDetailViewController" bundle:nil];    
  img.imagesArray = [heroArray copy];
  img.index = imgButton.tag; // AT THIS LINE IT SAYS POTENTIAL MEMORY LEAK
  [self.navigationController pushViewController:img animated:YES];
  [img release];
  </code></pre>
  
  <p>Please point me in right direction!</p>
