Finding out if an NSArray's contents are all equal

HI all,

I have category method added to NSArray that checks to see if its 
contents are all equal.
Basically the method just performs isEqual: to each item in the array 
comparing it to the first item, and if none return NO, then I return 
YES.
Otherwise I return NO.

What I'm wondering is, am I replicating any functionality in cocoa, 
that already exists? I'm curious if KVC cant be used to discover if 
an array
has all its objects the same value....

I just want to make sure, though I've looked around, I don't want to 
maintain code that is already been done by apple...

Thanks

Andre
