Creating a class to run a single action on multiple sprites

Question

I'm trying to rotate numerous sprites (about 48 different ones) around an arbitrary point (using this article: http://indiedevstories.com/2012/08/14/custom-cocos2d-action-rotating-sprite-around-arbitrary-point/ ) and I managed to create the custom category for it, but it only works on a single sprite. I've looked around on the site and tried to use runAction:[action copy] but it makes the copies rotating points crazy numbers for some reason. Then I tried to create a method for the actions and just call the method, but I keep getting errors for that as well. I've tried so many different solutions but no luck. So my question is, is there a way I can create another class that holds all of my sprites, and then run a single method to run an action on all of the sprites of the class?

Assuming you have an array called spriteArray containing all sprites you wish to rotate, it's as simple as:

for(CCSprite *sprite in spriteArray)
{
    CCRotateAroundBy *rotateAround = [CCRotateAroundBy actionWithDuration:1.0 angle:90 rotationPoint:screenCenter];
    [sprite runAction:rotateAround];
}
