How to use c-type array as ivar?

Question

I need a nice old-fashioned 2-dimensional array of integers in my program, but no matter how I try to declare it as ivar and then use @ property / @ synhesize, I get one compiler complaint or the other.

I declare

int spotLocations[10] [10] 

like ivar.

This works, but then the @ property / @ synhesize process never passes.

Answer 2

:

spotLocations = malloc(100 * sizeof(int));

:

int aValue = spotLocations[x + y * 10];
