You could try mass conversion of the arrays to strings like so:
NSArray arStr = NSArray.componentsSeparatedByString
(arLong.componentsJoinedByString("|"), "|");
I think that'll work.

Hi all
I have a slight problem which I am looking for the most efficient
solution:
I am comparing 2 NSArrays containing numbers, with the aim of
removing the numbers in one array from the other array.
The first array is obtained by rawRowsForSQL which returns the
numbers as Longs.
The second array is obtained by valueForKeyPath which returns the
numbers as Integers.
NSArray.removeObjectWithArray or NSSet.subtractSet don't work
because the objects are not equal.
The arrays can be very large, ie. 100,000 objects.
What is the best way to handle this?
thanks
mich
