Detect collision of a UIImageView with ANY object

I am writing an application where there is a central UIImageView and many other images are generated dynamically and move around the screen. I want to know when the central UIImageView collides with ANY of the dynamically generated objects. I know there is the CGRectIntersectsRect, but I have to specify the other object and this is not possible since there are many of them. Instead, I want to know when a collision happens with ANY object.

Please take a look at UIKit Dynamics. Here is the awesome Tutorial. Also Refer Apple Documentation

Since most of the elements are subclasses of UIView, you may be able to check for intersection with all elements using this code:

//imageView represents your central UIImageView
for (UIView *view in self.view.subviews)
{
    if (CGRectIntersectsRect(imageView.frame, view.frame) && ![view isEqual: imageView])
    {
        //Implement relevant code here
    }
}
