Objective-c: executing multiple transition animation blocks with ViewView

I am trying to make a simple Simon game (an increasing sequence of colors flashes, and the user should try to repeat this sequence). The way I do this is 4 UIViews with 8 images. So, UIView for red, blue, green and yellow. And I have gifs dark green, light green, dark red, light red, etc.

So, in my code, I use UIView transitionWithView: UIView imageView.image is used by default with a dark color image, and this unit goes to a light color image, and when finished returns to a dark color image (so that it looks “illuminated”).

- (void) animateColor:(NSString *)color
{
    ...
    //do stuff to default the dark and light image name and which UIView to animate based on the color parameter
    ...
    [UIView transitionWithView:imageView
                  duration:.5
                   options: UIViewAnimationOptionTransitionCrossDissolve | UIViewAnimationOptionAutoreverse
                animations:^{
                    imageView.image = [UIImage imageNamed:lightImage];
                } 
                completion:^(BOOL finished){
                    if (finished){
                        imageView.image = [UIImage imageNamed:darkImage];
                    }
                }];
}

This works great when I call it a single color method of this code.
