Passing an int array of variable length as a function parameter in Objective C

Question

I have the following code which works fine...

int testarr[3][3] = {
  {1,1,1},
  {1,0,1},
  {1,1,1}
};   
[self testCall: testarr];

Which c

Answer 1

Why don't you just use NSArray or NSMutableArray with NSIntegers? Those array classes are of variable length, and much easier to use.

This would result in

- (void)testCall: (NSArray *) arr {
    NSLog(@"cell value is %u", [[arr objectAtIndex:1] objectAtIndex:1]);
}

(Of course, you would also have to define testarr using NSArray.)

If you really want to use C arrays, making the method argument a pointer to an int with

- (void)testCall: (int*) arr {

will probably work (with the rest of the code staying the same).
