Thanks for the response. Yea, but its only for comparing arrays to 
arrays.

What I was looking for was if all objects in an array are equal to 
each other.
IOW, are each and every object containing the same equivalent value e.g
an array of NSNumbers all equalling 21.0 would return YES, else NO if 
the
contents' NSNumber objects varied in their value...

(Again, it seems apple hasn't a built-in method for this particular 
aspect...)
