I am trying to add a bounce effect to the animation below. Here is my code:

[UIView animateWithDuration:1.0
                       delay:.0
      usingSpringWithDamping:0.5
       initialSpringVelocity:2.0
                     options:UIViewAnimationOptionCurveEaseOut
                  animations:^{
                      // Coming from a value of CGAffineTransformMakeScale(0.001, 1.0)
                      self.myView.transform = CGAffineTransformMakeScale(1.0, 1.0);
                  }completion:nil
          ];

It's not working correctly. It becomes wider at the end of the animation then it goes back to normal. I want the width to bounce to a lesser value than 1.0, not more than 1.0.
