a 2 dimension array is just an array of arrays correct?
No. It isn't.
so it'd be something like
- (void)arrayManipulator:(NSArray *)aTwoDimensionArray;
You're mixing metaphors. The original poster isn't using NSArray, but, rather, C arrays.
+ (void) reValueInArray: (int[][] ) labelValue replaceValue: (int) oldValue withValue: (int) newValue;
In C, a multi-dimensional array is just one big, single-dimensioned array that uses fixed sizes for all but one of the component arrays to find a particular element. That means that you can't ever do something like:
There are several workarounds.
1) Use NSArray, as suggested in the first reply. That will solve this problem and lots more. With NSArray, you really an have arrays inside of arrays.
2) Treat the array as just a plain old pointer in the function signature, then cast it back to the properly dimensioned array.
3) Create a true array of arrays in C, using dynamic allocation. More trouble than it's worth.
4...N) Other options that are probably more trouble than they're worth.
