title: Add Slide In from Left to Right animation(transition) in addSubView
body: <p>I Try to imitate the <code>NavigationViewController</code>, very similar to default <code>MailApp</code> in <code>iPhone</code></p>
  
  <p>When clicking on a Mail summary, it should <em>slide-in</em> the mail details, and when <em>BACK</em> button is clicked, Mail Summary view is to be <em>slided-in</em> back again.</p>
  
  <p>This is what I have to animate the transition from Summary To Detail (<code>removeFromSuperView</code>)</p>
  
  <pre><code>CGRect temp = self.view.frame;
  temp.origin.x = 300;
  [UIView animateWithDuration:0.5
                        delay:0.0
                      options: UIViewAnimationCurveEaseOut
                   animations:^{
                       self.view.frame = temp;
                   }completion:^(BOOL finished){
                       [self.view removeFromSuperview];
                   }];
  </code></pre>
  
  <p>This is what I have to animate the transition from Detail To Summary (<code>addSubview</code>)</p>
  
  <pre><code>    CATransition *transition = [CATransition animation];
      transition.duration = 0.5;
      transition.type = kCATransitionFromRight;
      transition.subtype = kCATransitionFade;
      [parentView.layer addAnimation:transition forKey:nil];
      [parentView addSubview:myVC.view];
  </code></pre>
  
  <p>Now, that My First part of code is working well! Where-as the second part, I am just able to achieve the Fade-in animation. How can I bring in the slide transition?</p>
