title: How to access subviews in iOS6
body: <p>I create dynamically subviews in my ViewController like this:</p>
  
  <pre><code>CGRect imageFrame = CGRectMake(0.0, 0.0, 1024.0, 748.0);
  UIImageView *backgroundImage = [[UIImageView alloc] initWithImage:bgImage];
  backgroundImage.frame = imageFrame;
  [self.view addSubview:backgroundImage];
  </code></pre>
  
  <p>(Basically, I add various subviews to my view, which are containers for different types of content.)</p>
  
  <p>I am looking for a proper way now, to access these subviews later on, for e.g. fade them out.
  Is there a way to add these subviews with an identifier, so I can call them directly ?</p>
