Question

I want to make a 2D array like this

[[1,2,3],[94,22],[2,4,6],[1,3,5,6]]

What is the best way to do this for iOS using NSMutable arrays

Answer 1

You cannot create a static 2D array with differently sized rows.

Perhaps you can use NSArrays instead of C arrays to achieve this.

edit:
This is tedious, but you can try:

NSArray *array1 = [[NSArray alloc] initWithObjects:[NSNumber numberWithInt:2],[NSNumber numberWithInt:1],[NSNumber numberWithInt:3],nil]; 

And so on for each array, then

NSMutableArray *mutableArray = [[NSMutableArray alloc] init]; 
[mutableArray addObject:array1];
