Check out isEqualToArray: in NSArray.
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...)

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
