UIView animations with autoreverse

I have a problem with the setting UIViewAnimationOptionAutoReverse. Here is my code.

CALayer *aniLayer = act.viewToChange.layer;
[UIView animateWithDuration:2.0 delay:1.0 options:(UIViewAnimationCurveLinear | UIViewAnimationOptionAutoreverse) animations:^{
                    viewToAnimate.frame = GCRectMake(1,1,100,100);
                    [aniLayer setValue:[NSNumber numberWithFloat:degreesToRadians(34)] forKeyPath:@"transform.rotation"];
                } completion:nil ];

The problem is that, after the animation has reversed, the view jumps back to the frame set in the animation block. I want the view to grow and "ungrow" and stop at its original position.

Is there a solution without programming two consecutive animations?
