Just a final comment. The cast to (float) here is not required.
ippointer is already declared as a float* so ippointer[index] returns
data of type float as it is. I mention it because while here it's
merely redundant and harmless, your first attempt as posted to me off-
list has this cast as [NSNumber numberWithFloat:(unsigned
long)ippointer[index]]; Where the cast is most definitely not harmless
and in fact prevents the code from working. Throwing in casts without
understanding why you're doing it is a good way to introduce bugs, so
don't do it unless you really have to.
Also, what Nick said about the memory leak.
