如何检测特定NSMutableArray中的对象触摸？

Question

I have an NSMutableArray filled with different sprites. These sprites are all on the screen. How can I detect if a touch is landing on one of these sprites, and then do something if a touch on the sprite has occurred?

This is what I have now,

CGPoint touchLocation = [touch locationInNode:_physicsNode];

if(CGRectContainsPoint((starInArray.boundingBox), touchLocation))  {

Instead of (starInArray.boundingBox) , I want to be able to say something like (anyObjectInMyArray.boundingBox) .

Any way to go about this?

Thanks!

Something along the lines of this should work.

  - (BOOL) ccTouchBegan:(UITouch *)touches withEvent:(UIEvent *)event 
{

CGPoint touchLocation = [self convertTouchToNodeSpace:touches];    
        for (CCSprite *star in starInArray)
            {
                if (CGRectContainsPoint(CGRectMake(star.position.x - star.contentSize.width/2,
                                                   star.position.y - star.contentSize.height/2, star.contentSize.width, star.contentSize.height), touchLocation))
                {
                    //Do Something
                    break;
                }
            }
}
