Unfortunately not. To create a multi-dimensional NSArray:
NSArray *multiArray = [NSArray arrayWithObjects:
[NSMutableArray array],
[NSMutableArray array],
[NSMutableArray array],
[NSMutableArray array], nil];
// Add a value
[[multiArray objectAtIndex:1] addObject:@"foo"];
// get the value
NSString *value = [[multiArray objectAtIndex:1] objectAtIndex:0];
However, you can use C code in Objective-C (since it is a strict superset of C), if it fits your need you could declare the array as you had suggested.
