Is there an easy (WO or plain Java) way to derive the union of two
NSArrays?
If you mean as in a set then you should use NSSet...
((new NSSet(arrayOne)).setByUnioningSet(new NSSet
(arrayTwo))).allObjects()
...but if you mean actually a concatenation then...
arrayOne.arrayByAddingObjectsFromArray(arrayTwo)
cheers.
