title: Keep back to origin position an UIImageView
body: <p>I'm now implementing an <code>app</code>, for <code>iOS devices</code> so in <code>objective C</code>, and i was asking how to keep back to origin position an <code>UIImageView</code> after a rotation ?</p>
  
  <p>For example, i use my <code>UIImageView</code> like this :</p>
  
  <pre><code>CGAffineTransform initialPosition = CGAffineTransformMakeRotation(0);
  CGAffineTransform finalPosition = CGAffineTransformMakeRotation(M_PI/2);
  [UIView beginAnimations: @"Rotate animation" context: NULL];
  MySuperUIImageView.transform = initialPosition;
  [UIView setAnimationDuration:1.0];
  [UIView setAnimationRepeatAutoreverses:NO];
  [UIView setAnimationRepeatCount:1];
  [UIView setAnimationDelegate:self];
  MySuperUIImageView.transform = finalPosition;
  [UIView commitAnimations];
  </code></pre>
  
  <p>But after, i made it desappear for a time, using :</p>
  
  <pre><code>MySuperUIImageView.alpha = 0.0f;
  </code></pre>
  
  <p>And when i re-use it, i want it to be in the first original position, with no rotation. Is it possible easily ?</p>
  
  <p>Thanks in advance !</p>
