title: Check UIButton position after rotating UIView
body: <p>I have a buttonsthat I add on a UIImageView. With a method when the user touch the screen
  the UIImageView will rotate, I want to know if there is a way to get the new position of the  button after the rotation is done.</p>
  
  <p>Right now I'm getting all the time the original position with this method :</p>
  
  <pre><code>-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
  
      NSLog(@"Xposition : %f", myButton.frame.origin.x);
      NSLog(@"Yposition : %f", myButton.frame.origin.y);
  
  }
  </code></pre>
  
  <p>Thanks,</p>
