I have an NSArray arr
. It has a bunch of NSNumber objects. I'm trying to calculate statistics analysis on the array using GNU's GSL. GSL takes parameters as C-style arrays.
Is there any mechanism that can, for example, run 'intValue' on all of the objects in a NSArray object, and convert the results that to a C-style array?
I don't really want to copy the contents of the NSArray to a C-style array, as it's a waste of space and cycles, so I'm looking for an alternative.
