Objective-C IOS development: Animations 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 after the animation has reversed the UIView jumps back to the frame set in the animation block. I want the UIView to grow and "ungrow" and stop at it's original position.

is there a solution without programming 2 consecutive animations.

Thanks!
